Product Description

The Timbren FR150RC SES Rear Kit is engineered specifically for the 2021-2025 Ford F-150 Raptor 4WD and delivers a substantial improvement in load carrying stability and ride quality. When the rear of the truck is heavily loaded—such as towing a trailer, loading up adventure gear, or hauling payload—the factory suspension can sag and compromise handling. The FR150RC adds a pair of progressive-rate rubber springs that engage as load increases, maintaining a level stance and restoring proper axle geometry.

Installation is straightforward and requires no special equipment -the kit mounts directly into the factory rear bump-stop points and carries on silently. Whether you’re using your Raptor for weekend toy hauling or serious overland gear, this helper kit ensures you’ll maintain a controlled, comfortable ride both loaded and unloaded. It also contributes to safer driving by reducing rear-end squat, ensuring the front tires stay properly planted and the head­lights aim correctly.

Ideal for owners who tow trailers, carry heavy gear, or simply want to enhance their vehicle’s stability under load, the FR150RC helps deliver confidence on the road. Note: While ride height remains unchanged when unloaded, this kit does *not* increase the Gross Vehicle Weight Rating (GVWR) of your truck—always adhere to manufacturer-specified limits for payload and towing.
