Suspension Enhancement System (SES) Rear Bump Stops 4Runner (2010-2024)

Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles. Whether you’re towing your RV across the country or hauling hay down the highway, our Timbren SES kits level your load, making for a safe, controlled ride so smooth, you might forget you’re towing altogether.

How? Our Aeon® rubber springs deliver a progressive spring rate. As load increases, our rubber springs push back harder, eliminating squat, sway, and roll. After installation, there should be a ½” to 1 ½” gap between the rubber spring and vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride, too. What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, our kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.

Note: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.

Our Timbren SES kits are built to last. We back this up with a lifetime warranty.

Covered under this warranty are defects in material and workmanship, under normal use and service for the life of the vehicle on which the kit was originally installed.
