Product Description

The Rancho RS55384 RS5000X Rear Shock Absorber is engineered as a direct replacement for the rear suspension on stock-height 4WD *Ford F-150* trucks from 2009 through 2014. Built with Rancho's RS5000X performance valving, this gas-charged twin-tube shock uses Progressive Engagement Valving and a tuned compression control valve to smooth out road irregularities and maintain stability during daily driving or light off-road use.

Featuring a robust 2.25" shock body and nitro-carburized piston rod, RS55384 delivers durability and heat-resistant fluid performance while the protective dust boot and rubber bushings help minimize noise and protect internal components. Designed to bolt into factory rear shock locations without modification (excluding SVT Raptor models), this shock enhances rear suspension performance while maintaining a comfortable ride. Always check your specific year, trim, drivetrain, and shock mount style for exact match before installation.
