Rear Kit
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 kit is a premium suspension enhancement system designed to improve stability and ride quality under load. It keeps your truck and suspension level, ensuring 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 traditional air bag systems, which require ongoing maintenance and a lengthy installation process, Timbren’s suspension enhancement system offers a zero-maintenance solution. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.
This kit is compatible with multiple vehicle models, including full-size pickups. Check fitment details to ensure compatibility with your vehicle.
