The RAM 2500 is built for serious work — but even heavy-duty trucks can squat and sway under max loads. The Timbren Suspension Enhancement System (SES) DR2500D Rear Kit is engineered for contractors, ranchers, and tow-rig owners who rely on their RAM 2500 every day. Whether you’re pulling equipment, hauling material, or towing a fifth wheel, this kit provides progressive load support that kicks in automatically, keeping your truck level, stable, and ready to work without the hassle of air systems or maintenance downtime.
Key Features & Benefits:
- Aeon® hollow rubber springs that stiffen under load—reducing sag, sway, and rear roll.
- Comfortable ride when unloaded thanks to a designed gap (~½-1½") between spring and frame.
- DIY-friendly installation with all necessary hardware and steel mounting brackets.
- Lifetime warranty, zero post-installation maintenance.
- Rated Capacity: 8,600 lbs
- Kit height without spacer: 5.75 in; with 1″ spacer: 6.75 in
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.
