Overlanding, like life, is full of ins and outs, lot of what have you, lots of bumps along the way, and you might be thinking that something to put an end to some of those bumps or at least to smooth them out a bit might be a useful thing to add to your vehicle.
One popular option would be to add a second set of shocks that you only use if you hit a bump way too fast causing your truck to leave the ground in a risky maneuver called, in the parlance of our times, "sending it."
But all cars come with bump stops and if you're wondering if you need them I have a little story.
My first car was a 1999 Jeep CJ-7 and when I drove it home and drove into the driveway the gutter compressed the springs, and the shocks and the metal of the axle slammed into the metal of the frame and made a very loud and jarring noise. If the windshield hadn't already been cracked, that might have done it.
For a cheap fix I shoe gooed a tennis ball to the axle and that worked OK, but the tennis ball first popped, then fell off and I was back to banging.
Fortunately they make a bolt with a dome of rubber on the end that is designed to bolt to the axle or the frame and make a soft, yet still fairly abrupt stop to a big bump preventing the jarring of metal on metal. So I found one at the Jeep Dealer, bolted it on and down the road I went.
Now, I have this 2017 Toyota Tacoma with perfectly good factory installed bump stops. I had the idea to put on these Timbren Active Off Road Bump Stops to improve the ride, stop the bumps and really tie the truck together.
There are several videos here on TH-cam about how to install these, and if that's all you're after, have at it. Here, I'm going to answer the question, Do You Need Timbren Active Off Road Bump Stops on your Stock Tacoma.
First of all this is a Toyota, and as such, if it's loaded, it's overloaded. For some reason the springs they put on these are optimized for for unloaded performance even though they have this big cargo area in the back.
This truck came with a fiberglass topper, and I cary around a few things, not much really, but when I put the trailer on, the kids in the back and camping gear, it was hitting the bump stops a lot. So after Lightning Dragon and I went on an overnighter in the Pine Nuts to shoot some video for Roxor where we bumped down the roads with the Roof Top Tent on top hitting the stock bumps constantly, I decided to upgrade the bump stops first.
The stock bump stops are just a little cone of rubber that stands off the axle only a few inches and absorbs impacts when the axle gets close to the frame of the truck. The Timbren consists of all the parts you see here. and stands at least twice as far off the axle.
Assemble is pretty self explanatory, so I'll keep talking about whether you actually need these.
This kit came with the u bolts and shackles necessary to do a u-bolt flip as well. Stock, the u bolts point down and the ends of the bolts hang below the axle where they can scrape and get hung up on rocks. When I'm done here, they'll be sticking up with only the bends of the Us below.
This kit removes the brackets and bolts you can see hanging below the axle tubes here. Incidentally, when you're done the space between the u bolts will be a perfect spot to place the jack stands when you lift the truck.
You can see all the parts that are coming off here. The Lower bracket, the U-Bolts and the stock bump stop. An impact makes short work of this part.
Now, here's where the question at the start of this video comes in. The stack height of the Timbren bump stop and the u bolt flip plate is greater than the gap between the axle tube and the bump pad on the frame. Although it's worth noting that the truck has a topper on it and at the time of this mod, also had a Roof Top Tent on top of that.
I actually had to jack the truck up more to make space for it.
But that's OK, because since the U-bolts not point UP, you need a lot more space to get the impact in to tighten the nuts down.
Once you've got them torqued down you can mount the bump stop assembly and get the tire back on.
And as you can see, once I let it back down there was very little room between the bump stop and the frame. So little that once it was loaded, the bump stop was the suspension.
So, should you install the Timbren Bump Stops?

"You could use a ratchet if you hate yourself" LMAO I feel this. I will always always try to use my impact even if that means extensions and swivels
I’m using these bump stops on my 19 Taco. Very happy with them. Great video. Thank you.
Hey, really nice review and top notch outdoor filming as usual!
Best explanation why I do not need these aftermarket bump stops. I’ll invest in more robust leafs and shocks eventually.
Interesting and insightful. Been pondering this myself recently. Thanks.
Thanks, it's exactly what I needed to see and hear.
Super helpful video and commentary. I have a stock TRD Off-road and was thinking of installing these before going the AAL or full suspension upgrade route. Now I might just go the AAL route.
That would be my recommendation.
We have a 2018 Tacoma Off Road. On average we do approx 60-90 days per year of fully loaded tripping. The load out is approx 1000lbs, canopy, RTT, fridge, food, water, gear etc. After 1 year of use we installed this product as the truck was sagging in the back and they definitely helped. After 2 years and one blown out set of rear shocks (Bilstiens) we finally installed an Old Man Emu suspension system giving us a 2 inch lift. We found that the stock rear springs were done, totally worked out. Stock rear springs have 3 main leafs and one overload leaf. The OME kit has 4 main leafs and 2 overload leafs, not to mention that the shocks in the OME kit are a huge upgrade as well. The difference was night and day. Before the upgrade, when fully loaded, the truck felt like it was wallowing through rough terrain. It now handles it with ease and has greatly improved handling and capability. While I feel the Timbren product is a good stop gap, it just can't compete with installing a proper suspension to address the type of loads and use our overlanding truck requires. Doing it over again I would do the suspension immediatley as the stock suspension just isn't up to the task beyond mild load outs. For those with budget constraints these are an excellent, cheaper alternative to a full suspension upgrade but will not replace or duplicate what a proper suspension upgrade can do.
The best option though would be to have timbren or another set of good bumpstops and new suspension. The bumpstops and suspension work together as a unit so that when bottom out comes it is not as harsh. The stock bumpstops are hard as rock if you hit it, you feel it. While on the other hand timbren or other brands slowly ramp up to take the force therefore giving a smoother engagement and bottomless feeling with low to no bottom out jarring feeling
True on the suspension, but when the timbrens are so close to the axle they’re just as harsh.
Why are even comparing a $200 product to a $5000 suspension upgrade? Not relevant to this video!
A happy new year!! From japan.
That helps.. thanks.. I’m lifting my long bed 3 inches and will be running a camper shell and bed drawers so I’m on the fence on changing the bump stops.
Just installed Firestone air bags and they make a difference depending on the air pressure. I welded a tab clot connect the base cups to the axle on the inner side and this allows for articulation
My son has a 2017 Tacoma TRD Sport and was going to tow a 23’ Airstream. We installed it before actually towing and when he did there was no sag and it tows like a dream, almost forget its back there.
Good explanation!
Ok something else to add to the never ending Mod List!
I run the Active Offroad Bumps. Just had to costume fit for the 6in lift with Atlas leaf springs. Timbren has other bump stops for those people carrying heavy loads. Different part number!
thank you
These where to stiff for my Taco Air bags didn’t work either. But the SumoSprings where the way to go for me the blue ones where perfect !
At 4:04 never had that fit on my Tacoma running OME 2in lift.
Been using timbrens for years now.
I wish more people who make videos would give this much good info when they review something. I'm subscribed now ;)
Using these with the stock bilstein 4600's and leaf pack is delaying the inevitable axle wrap. They may save you a little time, but the og suspension should be upgraded to suit your needs to really enjoy these
Tis system is to help with the extra load. Like an air suspension. And so that the truck wont slant with the exta load.
These are bump stops, not overload springs.
I'm having a 2.25 add a leaf three pack put on my '23 tacoma to help with the load of all my work tools and contractor cap and was wondering if I should add the Timbrens as well. When I trailer things the added weight of the trailer tongue puts an extra 200 lbs...so it seems like it would be worthwhile.
I would do air bags.
As to overload springs you may get a permanent stiff ride but with the timbren it may feel stiff or firm only with something being towed or a very heavy load. If you have oversize tires you will likely not feel any difference in ride quality
What is a “what have you”?
Other bump stop options out there as well that are not as tall
Should I get bump stops for overall longevity of my truck even with no load?
Currently on 33s with 3’ front/2’ rear lift.
Thank you in advance!
I don’t think it’s necessary.
I have installed a 2 inch lift Dobinsons IMS.
On the driver's side i feel metal sound at very sharp turn while driving over dunes. Should i get the extended bumpstop?
Did you get huge tires too? Could be rubbing.
@AllTerrainFamily it's not tires...I installed bump stops...now its ok
shoegooed a tennis ball!! that's hilarious!!
It’s funny because it’s true.
I LOVED MY 1979 CJ 7. BOUGHT IT IN 1993, SOLD IT IN 2013 SO I COULD "UP GRADE" TO A 2005 RUBICON WITH ONLY 20K MILES AND AN AC....BIG MISTAKE. COMPUTER PROBLEMS, WIRING PROBLEMS, ETC. Thanks for reading....good vid by the way.
I run these bump stops on my truck with a 2” lift in the rear 3” in the front and I’m not a fan. When you do hit the bump stops it is smoother than the factory. But... you hit them so much more. I hit them so much that I’m thinking about going back to stock.
that's the point of them
Lmao that’s what they’re supposed to do
1.5 block is okay with the stock bump stops ?
I don’t know.
I just put kings 2.5 on my Tacoma and it’s lifted at least 2inches now. Wondering if I should buy a pair. The stock bump stops feel really harsh off roaring.
Sounds like you need to address the rebound valving first.
@@AllTerrainFamily had not even considered that. I found a guy selling the same kit you reviewed for $200, wonder if that alone is worth it on top of revalving
Maybe, but slowing down your compression dampening should do a lot.
Are you supposed to cut off the extra ubolt length when done installing?
You can.
@@AllTerrainFamily do you think maybe you are contacting those when cycling the suspension?
I don’t. The bump stop is much longer.
You definitely should
🙏😇👍🇵🇷
Timbrens are not bump stops! Timbrens replace the factory bump stops and are a active suspension component when the truck suspension is loaded.
That is the timbren SES, different thing.
These are the off-road timbrens bro there a different lol
Thank you for your correction.
Like me I think most of your subs started watching your channel for the content you already do. If you change it up you might lose subs as people may lose interest.
Unfortunately, tech reviews get more subs and views than the narrative content. However, I’m not going to stop posting the narrative content. Thanks for watching!
"I don't recommend these because your frame will sit on them if you have a load." That is literally the purpose of these...
No, it isn’t. They’re bump stops.
@@AllTerrainFamily Lol...
I’m confused
@@eliharper8669 You must be thinking of air bags. These bump stops are for 3" spring lift or more. Not for stock.
Pretty much you will need to replace your leaf springs. I have a 19 trd off-road and I have a cab high dog box on my bed. When I load all of my dogs in my truck, my leaf spring buckle(instead of smiling or being flat, they frown) my tailgate will be at my knees. A lot of people online say that the leaf springs suck and they sure do
There are several misunderstandings and misleading statements in this video. There is apparently a lack of engineering- and suspension knowledge here...
1. First of all, what you installed on your vehicle is NOT a bump stop BUT it's a helper spring. To be more specific it's a DOUBLE CONVOLUTED HOLLOW RUBBER SPRING that works together with your leaf spring suspension as a "spring assistant".
2. Hollow rubber springs have PROGRESSIVE spring rate especially a double convoluted hollow rubber spring like this example.
3. There are different types of hollow rubber springs providing different progressive spring rates. The spring rate and progressiveness is influenced by the diameter, height, wall thickness, core profile of the hollow rubber spring. Furthermore depending on, how you want to use your vehicle, the gap between hollow rubber spring and vehicle frame should be set accordingly.
4. For a helper spring the question is always, how the load should be distributed between factory leaf spring and helper spring. This can be answered based on the usage of the vehicle.
Summa summarum: if you felt that your hollow rubber spring is too hard, harsh and not progressive enough and you need more gap between spring and frame, you should simply select an other (softer, smaller, etc.) hollow rubber spring.
One more information about vulcanised natural rubber (raw material of hollow rubber spring): it's a material that can not be destroyed by any (static or dynamic) load and works fine for a decade without any problem on a vehicle. At the same time synthetic materials like PU, TPE, TPA, etc. can wear off much quicker.
P.S.: I'm former engineer of Hendrickson International responsible for commercial vehicle suspension systems in Europe.
Wonderful story: these are in fact called bump stops and are advertised as preventing harsh bumps. They are not overload springs or helper springs. But thanks for the comment anyway.
You are wrong. Those are in fact bump stops. Timbren actually sales helpers as well .
Mmm k.
There is a significant, yet subtle difference between the active off-road bump stops, as installed in the video and a helper spring such as the Timbren SES. The parts look very similar, but design intent is quite different. The "active" bump stops are there to reduce/soften the impact for the final suspension travel, plus reduce rebound energy... both aspects help with the handling, performance of the vehicle and the rear shock in dealing with these extreme compression/rebound cycles as experienced in off road conditions, particularly at speed. A Taco TRD off-road 4x4, V6 with double cab has an approx payload of 1155lbs (2021 model). If you carry heavier loads on road, the SES system is designed to reduce sag, and provide a stiffer progressive spring rate (under heavy load). If you carry heavy loads off road, then you should consider upgrading suspension/shocks (front and rear) to eliminate sag, squat, wheel hop, and sway.
