Active Off-Road Bumpstops provide off-road enthusiasts greater control over their vehicles’ 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. Unlike OEM bump stops, Active Off-Road Bumpstops are made from natural rubber. Just like our Timbren SES line, Active Off-Road Bumpstops carry a lifetime warranty and a satisfaction guarantee.

ABSTOR4R replaces the rear OEM bump stops on the 3rd gen (1990-2002) Toyota 4Runner. Upgrade to Active Off-road Bumpstops and experience the difference.

Active Off-Road Bumpstops are a bump stop upgrade that will improve your off-road experience in several ways:

Instead of the harsh jounce you get from regular bump stops, enjoy a much softer, smoother stop when your vehicle bottoms out.

Active Off-Road Bumpstops will not limit axle travel, but allow full articulation of the suspension system.

Remain in control of your off-road vehicle during hard-to-handle situations on extreme terrain and at high speeds.

Remove the stress to your body and your off-road vehicle. Active Off-road Bumpstops absorb the harsh slams when your vehicle bottoms out, allowing you to stay out on the trail much longer doing what you love to do.

Unlike hydraulic bump stops, Timbren Active Off-Road Bumpstops require zero maintenance. Zip. Zilch. Nada. This is a set-it-and-forget-it upgrade. No tweaks or refills required! Once you install your Timbren bump stop upgrades, they won’t need any supervision whatsoever.

You receive a lifetime warranty with every purchase of Active Off-Road Bumpstops. We have been designing and manufacturing Aeon® rubber springs for over 50 years and confidently stand behind our products.
