Product Description

The Fox Factory 985-24-043 Performance Series 2.0 Smooth Body Internal Floating Piston (IFP) Rear Shock is a direct-fit performance replacement for 1999-2007 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, including the 2007 Silverado 1500 Classic. Designed for stock ride height or vehicles with a slight rear lift up to about 1", this rear shock uses IFP technology to keep shock oil and high-pressure nitrogen separate, helping reduce aeration and providing consistent damping performance across varied road and off-road conditions.

Constructed with a durable 6061-T6 aluminum smooth body and application-specific valving, the 985-24-043 delivers improved handling and ride quality over factory shocks while resisting corrosion and dissipating heat efficiently. Quiet nitrile rubber bushings enhance comfort by reducing vibration and noise, and the direct bolt-on design ensures a straightforward installation on compatible Silverado and Sierra models. Sold individually, it's ideal for owners seeking a performance-minded rear shock upgrade within the 0-1" lift range.
