Timbren's Active Off-Road Bumpstops provide off-road enthusiasts with greater control over their vehicle's suspension travel. Using progressive-rate springs means that instead of a hard stop at the end of axle travel, the axle energy will be absorbed when bottoming out, producing smooth, predictable, and quiet axle engagement and disengagement. The progressive rubber springs absorb the harsh jolt at the end of axle travel, giving you a gentle ride the whole time.


Unlike your factory bumpstops, Timbren's bumpstops are constructed of a superior natural rubber compound, ensuring the bumpstops will continue to operate even after a lifetime of off-road abuse. And the steel brackets and disks are laser cut before they are painted with a durable, long-lasting powder coat finish to ensure protection and long life.

Video Transcript for Timbren Manufacturer Spotlight - Suspension Enhancement

Hey guys, it's Jake here with etrailer. Today we've got John with us from Timbren. He's gonna tell us a little bit more about what separates Timbren from the competitors. I appreciate it, I'm glad to be here. Timbren is a suspension specialist. We're based in Whitby, Ontario, so we are a true manufacturer in Canada and we offer a wide range of suspension products from light duty, from commercial all the way up to Overlander, Sprinter applications and trailers.

Now we've talked about a few of the options you guys have and we have plenty of options on our website. Right. We've got the SES kits. We've got the axle-less suspension. Right.

We've got your new coil inserts that just came out recently. But what would you say is your bread-and-butter at Timbren Yeah, no, our SES, suspension enhancement system, is definitely our bread-and-butter. Came out in 2011, won a SEMA New Product Award for best truck suspension. And really, the evolution you just mentioned here, you know, starting in 1968 all the way through now, 2024. But the SES kits are really the core of who we are.

And if you, if you would say at, in the level of stiffness on the market, what would you, would you put yourself in more in a heavy duty side for the SES kits or is it more of a lighter duty Yeah, great question. Lighter duty, we certainly can have a product for commercial and heavy duty, but in '82 when SES was introduced, it was purposely introduced for that, that light duty market. So we start with 1500 and again, go all the way up, but by far really popular with that 1500, 2500 crowd. That kinda leads me into my next question. So we talked about, your specialty is kind of in the lighter duty, but do you have an option for the heavier duty for your sprinter vans and maybe for your truck bed campers Yeah, absolutely.

We do have SES kits for truck beds, truck campers with a higher center of gravity. That creates a new kind of set of problems with the sway side to side. So we have severe duty kits for those. And it uses a single convoluted AON versus a double convoluted to tackle that problem of side to side. And the same thing with the sprinter van. It uses a rectangular shape Aon, but it's there to do the same deal that side to side sway because they're so top heavy, it'll eliminate that. Okay. And then we've had an instance here at etrailer that we had a van that was very, very heavy on the one side. Is there anything that you guys can do personally to help, I would say, I guess customize that kit for that particular user Yeah, by all means we would want that individual to contact us. We would ask a couple questions, see where that weight is distributed and we can actually produce an AON with either a stiffer hardness or durometer or a softer durometer and that will help level it out. So yes, we can take care of that for 'em. And I think that'll really, really help people to get their rigs dialed in because who knows what they're putting in the campers afterwards, after they buy 'em. They come from the manufacturer already heavy on that side and they're trying to load stuff on the other side to try to even it out. But knowing that there's a solution that you can customize for your rig no matter what the weight is on either side is really, really cool. Yeah, absolutely. We're happy to take care of 'em and again, there's no charge for that. Awesome. Now to kind of wrap things up, what sets Timbren apart from a lot of other manufacturers out there Well, I think there's a couple things. We're a family run company and our longevity, you can't deny, 1968 to 2024 and our warranty, we have a lifetime warranty regardless of how old it is. We will take care of it, replace it, limited lifetime warranty, and the hundred day money back guarantee. Very cool. And that's whether or not you're the first owner Right. And yeah, we're not asking for receipt, who'd you buy it from It'll be taken care of. Just give us a ring and we'll take care of it for you. Very cool. Well thank you again for meeting with us. Appreciate it. It was a pleasure to work with you. Thank you.

  • Recommended Suspension Enhancement for a 2024 GMC Canyon Pulling a Trailer
    Personally I wouldn't go with Timbren's for your needs. They're essentially rubber bump stops that prevent your suspension from flexing when weights placed on the rear of your Canyon. The major issue with them is comfortability when you are not towing your trailer. These significantly affect the range of your suspension which can leave you with a stiff rigid feeling in the rear end. Plus if you hit a bump while there's weight on them they tend to bounce. Instead, I recommend the SumoSprings...
