Timbren Active Off-Road Bumpstops - 2nd/3rd Gen Toyota 4Runner (Rear Kit)

Sale price$316.90



Factory bumpstops just can’t handle hard slams from off-roading. Harsh bottoming out, bone-rattling bumps, and dangerous uncontrolled handling can ruin your off-roading or overlanding trip by destroying your suspension and shocks.

But with Active Off-Road Bumpstops, you can hit the trails without taking damaging hits to your suspension.

How? These bumpstops dampen blows from bottoming out — making for a softer, safer ride over the biggest bumps, dips, and whoops.

Instead of a jarring stop when bottoming out, energy is absorbed through our Active Off-Road Bumpstops, producing smooth, quiet axle engagement. This is thanks to the progressive spring rate of our Aeon® springs.

That means reduced stress on your suspension and decreased driver fatigue. So you can explore more, comfortably and in control.

And unlike hydraulic bumpstops which require frequent servicing, Active Off-Road Bumpstops allow for DIY installation and need zero maintenance.
