FR250SDG

The Ford F-250 is trusted by contractors, farmers, and RV owners — but stock suspension isn’t built for constant heavy-duty use. The Timbren SES FR250SDG Rear Kit adds progressive Aeon® rubber springs that provide thousands of pounds of support for Ford F-250 Super Duty models. It prevents rear squat, reduces sway, and preserves ride comfort when unloaded, all with a quick bolt-on installation and zero ongoing maintenance.

Key Features & Specs:

• Progressive Aeon® rubber springs stiffen under load

• Stops squat, sway, and roll when towing or hauling

• Smooth unloaded ride quality

• Simple DIY install with included brackets & hardware

• Heavy-duty durability with a lifetime warranty

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.
