I bought a used 2018 GMC Sierra 1500 4wd and it had the 3.5 Rough Country Lift already installed (Who can Fix this Fxxxking truck.. ????? keep reading) but the truck had factory rims and tires so i assumed the prior owner wanted his custom wheels and tires and i figured i would get what i wanted and bought the truck. Same day i bought the truck I put toyo open country AT 33x12.5x20 with fusion wheels on and it looks freaking awesome. Immediately blew out the right front CV joint. I replaced it and 6 weeks later blew again. The next time (3rd) the extension axle from the differential broke at/between the CV plate and the differential extension housing. wow. that meant dropping transmission and taking apart differential and replacing the axle shaft and axle shaft housing and the CV axle for the 3rd time. the mechanic recommended welding bump stops back on because the CV joints were at a terrible angle and were basic in bind with the slightest deflection of the struts. so we welded them on. problem was now i could not get the front end to align because the tires were in at the top and were maxed out on the cams.. so back to the guys who did the other work and they figured out the spindles were not installed on the kit when the kit was installed making the CV angle way to much. So i installed the spindles and cut the make shift crappy bump stops off and thought finally i should be good to go. NOPE... blew out the same damn shotgun side CV joint on the way home !!!! I am writing this in today the same day that i just blew out the CV joint on the way home. I am so freaking tired of this.. PLEASE what is the deal here? Who can Fix this Fxxxking truck.. ?????
Did you ever figure out what the actual problem was & got it fixed? Seems it’s more good reviews than bad. I myself about to order the kit after an extensive research & I haven’t come across a lot of negative reviews so far
@@nkonie7177 Yes I did finally get resolved after even more drama. So finally after 2 more 4 wheel drive shops including 4 Wheel Parts I called Rough Country again and this time one of the reps actually knew what he was talking about. He asked me to send pictures, and give measurements of how far the fenderwell was from the ground. As it turns out.. whoever installed the original 3.5 lift kit added spacers at the top of the shock housing which pushed the entire (IFS)system down farther to increase the angle of front drive cv axle shafts. But more than that was the shocks had failed and were allowing droop way beyond the allowable angles. So they sent me the new complete M4 Strut - coil assembly and I took the spacers out and with that the whole IFS system stayed at proper droop when the truck was unweighted in the front causing droop. WOW.. HUGE difference in ride quality and steering control and since the new M4 setup I have put over 40,000 miles without issue including going hunting in very rough terrain and hitting a few whiskey curbs along the way etc. I would definately recommend this new kit version. Call Rough County customer service if you have any doubt about installation. make sure you follow directions and dont let 4 wheel drive shop add or take away anything because they think they know something and just dont understand what they think they know. Good Luck
@@vikkleo I’m thinking about installing the same lift from RC, I have a 2012 1500 4x4 with 5.3L, what kind of MPG loss did you get after install? Since you had installed about a year, you experience any problems with it?
Just finished mine on my 2015 Silverado, looks great. One question: can I add a 3/4" thick front lower strut spacer, in order to lift the front an additional approximate 1.5" ? I know I would need another alignment, just wondering if this works with this exact lift I just installed. Thank you!
Yes... i did this to mine and it really helped bump up my lift to fit 35's in those square wheel wells. Very little trimming was necessary in the rear part of the wheel well. Hope it works out for you as well.
This suspension system was developed using a 33 x 11.5 tire with factory wheels. Examples of tire sizes that can be used are 285/75R17, 285/65R18, or 285/55R20. Note if wider tires are used, offset wheels will be required and trimming may be required. This one has the 33x11.50-18 on it.
I only have a 2 inch level on my 2014 and fit 305 55 R20s with 20X9 +0 offset. It fits fine but does just barely rub. Anything bigger you need to run a 5 inch of bigger lift. The brand new GM trucks however have the round wheel wells so those might be different
The knuckle kit widens the track width by 4" and requires the rear wheel spacers and aftermarket offset wheels. The bracket kit retains stock track width and allows you to run the stock wheels.
@Rough Country I just bought a truck with I believe this kit. I see the strut spacer on top and I see the skid plate under diff. How can i tell if it has RC Knuckles vs stock?
If I'm not mistaken the knuckle is slightly taller at the points where the ball joints go in. For sure the part that receives the upper ball joint is at an angle so it's less stress on you ball joint compared to the stock knuckle that isn't at an angle
The strut spacers in this kit are 2.06" tall. You get the lift from what the spacer does to the geometry of the suspension and not the dimension of the spacer.
Great video, straight to the point. Installing this exact kit in 2015 Silverado next week, I am beyond excited!
Did you do this on stock struts ?
@@317_vrod yes
This kit kicks ass im running it on my 2018 done few videos on it
Justin 315 what size tires do you have??
Are using the wheel spacer they recommend
Why do you have to cut the bump stop if you are getting more clearance with the new knuckle??
They also used a strut spacer

What size tires and rims are on it
Take a shot every time he says remove
Just finished install mine on my 2016 silverado awesome kit love how easy it was to put on looks great thank rough country
Hows the kit holding up? Any problems?
@@jtitybeatzb1349 no problems everything running OK
Did you have to cut a notch in the cross member and cut the cooling fins off the differential?
@@daviddavis418 l did both and still no problems with truck

I just got mine and the kit comes with 4 1 inch spacers for the diff do I have to use all 4 or just the 2 in the back of diff
How do you remove the Ball socket bolts? I can't get a wrench or socket on 3 of the 4?
How big of tires can you run with this 3.5 lift kit
Are you supposed to put the spacers in the all four side a of the different or just the back
Do you have install vid for a 6 inch lift ?
Does this avoid factory and extended warranty?
Will this kit work with your 3.5 shock and strut ?
What size tires and wheels are used on this truck?
This suspension system was developed using a 33 x 11.5 tire with factory wheels. Examples of tire sizes that can be used
are 285/75R17, 285/65R18, or 285/55R20. Note if wider tires are used, offset wheels will be required and trimming may be

What brand are those wheels? I’ve been searching for hours lol
What does the drop knuckle actually do differently? Why not buy an UCA? Does the knuckle or UCA change the camber/caster?
No it changes the angle of the upper ball joint so it’s not in a bind.
@@stevenwitt2555 That’s also what UCAs do. That’s not a differentiator. Hence my question.
What size tire and wheels are in the video? That setup is perfect.
I want to know also
has anyone done this with just a floor jack err what?
Do you still have to notch the crossmember and front diff if using the the roughy country lifted strut instead of the spacer???
Yes because you’re dropping the diff 1”
Besides parts what is the difference between the knuckle lift kit and the control arm lift? I’m debating which one to get.
The knuckle kit widens the track width by 4" and requires the rear wheel spacers and aftermarket offset wheels. The bracket kit retains stock track width and allows you to run the stock wheels.
Rough Country Which one would you consider better suited for a ranch truck? I typically have a quad in the bed.
They require negative or positive offset?
How would 12 inch -44 offset look on this lift?
Are wheel spacers needed if running factory wheels. I saw where it was and option
I'd like to know this as well. I've seen some conflicting information.
yes .025 spacer is required for the front if using stock wheels
Will this set up work well with 295/70/18
Will this kit fit without the drop knuckle?
Any body know the tires spec on this video ?
What are the side steps used on this truck
Do I need to buy the upper control arms too if I buy this kit?
Yes
No, the spindle eliminates the need for changing the upper control arms by providing a better angle.
@Rough Country I just bought a truck with I believe this kit. I see the strut spacer on top and I see the skid plate under diff. How can i tell if it has RC Knuckles vs stock?
Crib knuckles are 3.5 inches taller than the stock one
@@eastsidee9435 wrong lol
@@eastsidee9435 lift is achieved via the 2.06" thick top strut spacer. Knuckle just fixes the upper bj angle and allows CV axle to clear lower arm
Thanks for video! What exact brand and size are those tires??
285/65-18 Nitto Trail Grapplers.
Too many cuts
Is the knuckle kit only for 4wd? Or could it be on 2wd?
This is the 4WD only option
Eduardo Perez why would you lift a 2wd truck in the first place? 🤷🏻♂️
Will I be able to run factory 18/10.4 wheels with 33” tires
Yes you can on this kit.
Do you need wheel spacers in both front and rear if putting Max recommend tire size on stock rims? Website doesn't specify?
No just the PN# 1065 for the 1/4" front wheel spacers on the stock wheels. Those 3.5" knuckles do not widen the track width.
Imagine installing all this on a rolling recall.
Will this kit fit a 2017 Sierra Denali with the magneride?
Does NOT fit GMC Denali models with Magnetic Ride Control.

how come these dont need upgraded upper control arms
You would with just a spacer
However that’s where the new knuckle comes into play
It corrects the geometry
Does the knuckle raise the vehicle, or is it just the coil spacer on top of the strut ?
The lift comes from the strut spacer not from the knuckle/spindle.
@@RoughCountryTV What does the new knuckle provide then, in other words what does the new knuckle do? Thanks!
@@dsmith584 I have the same question...I bought the kit with the new upper control arms and full lifted strut but no knuckles.
If I'm not mistaken the knuckle is slightly taller at the points where the ball joints go in. For sure the part that receives the upper ball joint is at an angle so it's less stress on you ball joint compared to the stock knuckle that isn't at an angle
You get the knuckle or you get the forged upper control arms . Either option is to reduce stress on ball joints
How tall is the strut spacer ?
The strut spacers in this kit are 2.06" tall. You get the lift from what the spacer does to the geometry of the suspension and not the dimension of the spacer.
Will there be a version of this 3.5 inch lift for denali models soon?
We will be expanding our line later this year. No ETA at the moment.
Can I ask what brand the rims are?
No
All that for 3.5 inches! Im good

Can I add 1.5 body kit with it
Yes you can add a body lift with the 3.5" suspension lift to make it a 5" combo kit.
Yes you can add a 1.5" body lift with any suspension or level kit.
oh ok then Piece of cake then gotcha.
Cutting the bump stops hard pass from me
I did every step and now my truck is lower than a 95 Honda civic 😂

Buy a $300 upper arms? Naaaah cut the bump stop
It rides like crap
Lift comes from the strut spacer. What does the new knuckle provide then, in other words what does the new knuckle do? Thanks!
The knuckle is lifted to help maintain proper geometry and angles on the upper ball joint, tie rod, etc.
Can I use a 35x12.5x20 tires with this system?
295/55-20 is max size you can run on this kit
1234ahhh1 I have 33x12.5x22 but I had to do some minor cutting
I have 35x12.5s on this kit. No problems at all. But you can’t have offset rims. I have stock rims.
Will this work on a 2wd truck?
No this is the 4WD kit. We don't offer a 2WD option at this time
in the knuckle kit. Just the upper arm kit
