Timbren Suspension Enhancement Systems

Timbren Active Off-Road Bumpstops replace your factory bump stops with progressive units that cushion the impact when the suspension bottoms out. Timbren describe them as cushioning blows from bottoming out so you can hit the trails without taking damaging hits to your suspension and shocks.

Worth being clear about which Timbren product this is: the kits here are the Active Off-Road line, aimed at trail impacts. They are a different product from Timbren's SES Suspension Enhancement System, which is aimed at load support and rear sag when towing or hauling. This collection covers Tacoma, 4Runner and Tundra applications.

About Timbren Active Off-Road Bumpstops

Factory bump stops are a block of rubber whose job is to stop metal hitting metal. They do that, but harshly. Timbren Active Off-Road Bumpstops replace them with progressive units that absorb the hit gradually instead, which is what saves your shocks and suspension components on rough ground.

Which Timbren product this is

Worth being precise, because Timbren make two things that get confused. The SES Suspension Enhancement System is for load - it stops the rear end sagging when you tow or haul. Active Off-Road Bumpstops, the kits in this collection, are for impact - they protect the suspension when the truck bottoms out on a trail. If your problem is a sagging rear under a heavy load, this is not the right kit.
