Matt...one of the best videos ever put out on suspension. It's been such a mind boggle to understand this. This makes it totally comprehensible. thank you.
Good presentation ...Matt I have query about shackle length design. Spring span length 480 and spring height 145 mm,no of leaves 6 May I know what length required for shackle and installed angle minimum.
Wow!!! Why didn't I find this video before!!! This is gold to me!!! My old F350 rides like an old wild west chuck wagon. Thanks so much for this video!!! 👍👍👍
Finally getting around to trying to order new leafs. One thing I'm finding frustrating is that few mfg's list the same specs. For example Doorman tells you : pack thickness, capacity, and arch height. (example: 4 leafs, 1 overload, 1.75" thick, 1150lbs cap.) while many other aftermarket mfg's only say "3-4in lift springs" and don't have any arch thickness or capacity rating... It's hard to compare springs from Rough Country, BJ's offroad, Skyjacker or BDS without any actual specifications.
Appreciated! Only improvement (suggestion) would be to have used a scale to measure the change in resistance (spring rate) between each of the mounting locations. Expressed as a percentage (rather than in pounds for the sake of the model). Great demonstration and the bloopers were cool too!
Hi Matt, Enjoyed the info, one thing to help test spring compression and angles Is to disassemble the both spring packs, using only the main spring and make a small block to replace all the other springs that have been removed, so if it 3 inches of spring that have been remove add in a 3 inch block put your bolt back though the block and main spring mock both springs on the vehicle than with a jack you can compress and release and let hang and get your angles of the shakles and find your bottoming points with your tires on and off as well and side to side relaesd and compressed with out the resistance of all the srings as well as measurements for shocks and brakes line mods, drive line lengths and so on Thanks for the video!
Outstanding video Matt! I have been building leaf spring Jeeps for years and only 'educatedly guess'ed' the shackle length and location. But now I have some good reliable math to use to take out the guesswork! (Yes, I can do math!) Loved the part "but wait!" I have watched this video about 5 times to make sure I understood and laughed every time!!
Great video, not a lot of people running leaf springs in off-road anymore. Ive got some custom made national springs in my chevy 4wd super long and super soft . I love them.
Wow thanks! Isn’t it crazy? That’s why I made the video. I actually reached out to some TV personalities and asked them to make but heard nothing so I just decided to figure it out myself.
Thanks Ben! Yes it was a lot of work but it’s also one of my most watched videos so totally worth it considering how many guys have gotten something from it.
Very helpful! My truck has a front axle swap. And the ride is awful, while the spring may just be too big. The shackle is 90° at ride height. Time to go make some new mounts and shackles!
Thanks! Yeah that’s why I made the video. It’s shocking how little information there is out there. I was kind of hoping it would spark others to make better videos.
Thanks for the leaf spring demonstration, I just checked the 55 truck rear leaf spring shackle I put on 10 years ago, it's straight up & down, there's another hole on the bracket that will change the angle to more movement. Now I know why I hit my head on the ceiling when I drive over a dip too fast. Thanks
As long as the information is correct then this is a great video. Gave me a expanded understanding and reinforcement for my spring suspicions. There are still a lot of questions I have about how various leaf pack mods and setup alterations will achieve different application goals. I think the main scenario that comes to mind is how a longer shackle will affect perceived on-road ride comfort when installed on the same leaf pack and using the same mounting points. This would be ideal for a DIY mechanic with basic tools and a limited budget that wants a more comfortable on-road experience with zero to little (driver+personal items/tools in cab=200-300lbs) additional payload. The problem I've been having is trying to get a smoother on-road ride quality out of a 2003 PreRunner TRD Double Cab. It has thick 3/1 two stage over-spring leaf packs. I'm unsure of the spring rates. Every aftermarket suspension component available for this truck is for lift, load, and/or off-roading/overlanding which all seem to equal a harsh on-road experience unless you're willing to drop $3k+ on 2- or 3-way adjustable reservoir coil overs and shocks and another $1k+ on progressive leaf packs, but even then you'll end up with a 3"+ lift with a 500-1klb payload increase which will then require new control arms, brake lines, diff drop kit, panhard correction kit, new ball joints, an alignment...the list goes on and on. You can do all that to this truck, but so far I haven't found one stitch of information about how to improve the ride quality for a daily driver aside from the snarky comment of "leave it factory". I refuse to accept this.
Andrew James thanks Andrew. Good luck! I had a guy pull up in a lifted Scout yesterday to bus some parts I was selling. As soon as he got out I’m like “does that thing ride really rough?” And he’s like “yes, how’d you know?” :-)
But I have a question in my mind🤔 ıf we replace the leaf springs to a closer point towards to fixed point ,Will it raise the cars rear because of curve on the leafs. I don’t wanna raise the rear of my car I just want more flexible rear leaf springs.
This has been the most educational video I've ever seen about leaf spring tuning and shackle angles effecting the ride. Im running pro comp springs and there isn't enough desired flex i need. Might be i just need to adjust or buy shackles before changing out springs. Thanks again
Great video on all fronts! This is what TH-cam was made for if you ask me ... edutainment. Thank you for taking the time to do this. I stopped in the middle of the video tho make sure I wouldn't forget to trip that "wonderful"(agk I just threw up in my mouth a little) algorithm for ya, but I might have some questions at the end ...
Hi Matt, 1986 Isuzu Trooper 10 bolt rear end/drum brakes/ leafs with non pressed eye bushings/ 70mm shackles. Upgraded to 89 Trooper RS leafs/pressed front eye/ 2” longer leafs than ‘86/90mm shackles/ about 150lbs greater load capacity. So I noticed my shackles were at a steeper angle due to using the stock 86 mounting points on frame. A bolt on upgrade. So I got a smoother ride and can load up the trooper with an equal weight loaded without bottoming out over rough stuff. Thanks for the video! Now I know exactly what my instincts were telling me why to do the mod in the first place!
I know this is an old video but thanks. I have argued with people many times about this. I changed the angle on my yj with waggys and the springs got softer. Had people saying that doesn't change the rate. At least now I can point them to real world calculations. It's a leverage arm people!
The internet is a spooky place Just before Christmas I ordered new rear leaf springs for my Jeep XJ I watch this video 3 years ago This morning I wake up and it's back up on my feed so I'm watching it again I did not look for it I did not look for other leaf spring videos
For the win!! A couple years of searching for how to figure shackle angle and I’ve found it!! I moved my springs inboard the frame on my Ranchero for more tire clearance. Doing so with a kit. A kit for a Falcon car not a Falcon Ranchero. The Ranchero wheel base is longer. Think station wagon with no rear top. Anyways had to fab my own mounts for shackles and they are wrong. To steep under the weight of the car. No hardly and action at all. Not good for hooking up on the track. I have traction bars still no action for a launch. Stiff as a board. I’m so glad I’ve found this. Now I can cut that old shit off and do it up right!
AWSOME VIDEO! Thanks so much for making this. I love seeing stuff like this. I’m currently planning out a front a rear axle swap on my Jeep. I’m also putting in a new sua rubicon express lift. This information was hugely useful and encouraging for me. I can give myself an improved shackle angle and stretch my wheel base a little at the same time! Thanks again!
I just did this with a 12 inch lift leafs on my square body suburban up front moved my shackle eye hanger forward up on frame and longer shackles definitely true in facts .and the 12 inch leaf springs actually work by doing that . instead of just bolting them to the factory location.i got video up on here under my name
I have all my parts together to do a leaf spring swap on my CJ and wanted info on shackle angle. Best I could find so far was avoid inverting. This helps a lot. Thanks.
Great video. I bought my truck with a lift already on it. Monster lift kicks like a mule. No shackles. That math is going to be handy to solve my mystery.
Thanks matt, really learned a lot from your thorough explanation! Planning to build my Jeep Roadster here in the Philippines, your lecture would be a great help for its proper leaf spring mounting
There's another variable - the more leafs you have, the more friction between each leaf in the pack creating resistance on compression to make a smoother ride.
If ride quality & performance of your vehicle is important to you, then you should NEVER have to deal with Removing a Leaf from your Leaf Pack to Decrease your spring rate for a softer ride. That's the Beauty of buying Custom Leaf Springs from DEAVER SPRING INC. They make sure that the springs they make are absolutly perfect for each vehicle before they leave the front door. Obviously they are not perfect and stuff happens from time to time, but everyone I have spoken too about Deaver says that their Customer Service is next level... ( like your at Grandma's house waiting for the 2nd batch of cookies in the oven because the 1st batch was cold. ) And the awesome part is that Deaver Springs are 100% USA Made, so they will rework and remove a leaf from the leaf pack themselves all Free of Charge if you weren't happier than a kid with fresh baked cookies from Grandma's house. The things I have heard about Deaver and what they do to help a customer are things you don't her about companies doing anymore. Good Values I guess. I just know that the guys at Deaver Spring would have plenty of better ideas than simply removing a leaf & done..... that was my point. I Definitely enjoyed the Video Matt & I love the Bronco! Thank you!
Very, very helpful video Matt. Very easy to follow and you did a great jog. I am one of your slow learners, and I would appreciate it if you could list the steps for calculating shackle mount location.
thank you very much, been restoring my 68 scout for a while now, come to this point now ,just want to get it right it will be hard to undo it if it is not right, huge help with the info, please take care .
Awsome job, you can almost feel the spring rates as you move the springs. Question everything! Just don't get paralysis from analysis - get out and wheel, when it brakes, fix it and get back out 😉
Don't apologize for the color! That pale yellow is rad!
Matt...one of the best videos ever put out on suspension. It's been such a mind boggle to understand this. This makes it totally comprehensible. thank you.
Matthew Mugar wow what a compliment! Thanks Matthew!

No one could explain my question but you did .
Thanks for that paractical example. With out it i couldn't decide what to do.
Excellent demonstration on how leaf springs and shackles work!
Thank you for to the point and no off topic ramblings! Logic was telling me that diagram was wrong.
You cracked the real puzzle of leaf spring stiffness relationship wrt shackle angle.
Thank you. you really illustrated how the leafs and shackles interact on a leaf suspension. learned a lot

Great video bud. i have always eye balled the shackle angle and run flatter springs. Usually works really well.
I’m not a leaf spring guy at all, but now I feel prepared to become one of the day comes! Thanks professor.
whole video went over my head. I'll come back to it when I can give it my full attention...
For sure. You need to grab a coffee and squint real hard, but there’s good information in there.
Very good clear explanation. Thank you so much
Thanks Caesar!
Appreciated! Only improvement (suggestion) would be to have used a scale to measure the change in resistance (spring rate) between each of the mounting locations. Expressed as a percentage (rather than in pounds for the sake of the model). Great demonstration and the bloopers were cool too!

You did so amazing on this video. I Will save this video to watch multiple times. Lot of work went into this and I appreciate it so much
Parker Wilstead thanks Parker! Sorry it took so long for my reply. Been swamped lately.
Matt's Garage no worries, keep up the good work!
Great explanation. Found this by accident and learned the answer to questions i didn't know i had about my ranger. LOl😂
Great video, I watched it a few times to realize I can change leaves to fix that shackle angle! Great job, thanks! :)
This is very interesting. I am in the process of doing a 63" spring swap on my Tacoma so this information is very useful. Thank You!
mike diltz cool, let me know how it turns out. Good luck!
How did it go? I am in the process of doing that on my 1st gen 4runner. What angle did you end up going with? And how do you like them so far?
@@jesusakadice sorry but I never ended up doing it. I sold the truck when I saw how bad the frame was rotted.
Great video, not a lot of people running leaf springs in off-road anymore. Ive got some custom made national springs in my chevy 4wd super long and super soft . I love them.
Thank you! I learned so much about my favorite kind of spring. Gives me a good idea on what to look for when working on my 73' C10

I watched this working on a truck. Came back to it while contemplating lifting a firebird for slicks. Im seeing a longer shackle will change my angle
Great lesson on shackles. I've searched the whole internet to know how exactly these things works.

When you order Dever lift springs for a stock vehicle do they automatically make the leaves longer to compensate for shackle angle?

“Wait wait, you can do this” xD legend thank you for the informational and emotional support
Amazing demo , I concept of shackles is a lot clearer now👍👍
Thanks so much!!! I'm doing a solid axle swap and it was very nice to see the angles.
Perfect video. Im new to leaf springs. And this was very helpful. Got a thumbs up from me
This is the best video on TH-cam
Very informative. Great video. Great explanation.
Thanks for helping me understand effective spring rate as it relates to leaf type suspension. Subbed.
Phenomenal explanation! Thank you. 👏
The equation is awesomely helpful, thanks for the video!
Thankyou for all your effort to help others mate. Cheers. Great vid

joshua Atkins exactly. You can’t talk rate without considering EFFECTIVE rate!
@@MattsGarage Can you do a video on calculating effective rate?
The internet is a spooky place
Just before Christmas I ordered new rear leaf springs for my Jeep XJ
I watch this video 3 years ago
This morning I wake up and it's back up on my feed so I'm watching it again
I did not look for it I did not look for other leaf spring videos
Spooky indeed. I don’t pay for promotion or anything. That’s the algorithm
Aesome explanation.
Ppl thought i was stupid for having a 30°angle shackles. I told them its ok, not everyone is good at math.

Great video. I bought my truck with a lift already on it. Monster lift kicks like a mule. No shackles. That math is going to be handy to solve my mystery.
Thanks Ken. When you say “no shackles” do you mean that both ends of the spring are literally bolted to a fixed mount!?! That would be lunacy.

Very cool. Thank you very much.
Excellent video. Good job
Awesome video !!! Very helpful
I agree with Matt, very educational indeed, salamat po -from Philippines here.
There's another variable - the more leafs you have, the more friction between each leaf in the pack creating resistance on compression to make a smoother ride.
Jay R yes but it’s pretty negligible. most of those leaf springs have plastic pads between them
Thank you, very informative 👏👏👏
This is awesome. Thanks for making this video. Confirmed a lot of what I was thinking and also learned a lot.
