Detailed Description
Rancho RS551767 is engineered as an all-in-one front suspension strut and coil spring assembly for Ford F-150 and Lincoln Mark LT fitments. The RS5000X Loaded design combines the strut assembly into a single service unit, helping reduce assembly time during front-end suspension repair. Rancho’s Cross Tuned technology is used to improve control and ride balance across everyday driving and rougher terrain, while the gas-charged construction supports consistent damping response. This part cross-references Monroe Shocks & Struts (e.g., 153031, 171361) for the same application.
What It Helps Address
- Front-end sag or loss of factory ride height
- Worn strut performance that affects steering control
- Excessive bounce or unsettled ride quality
- Reduced handling stability on-road and off-road
- Time-consuming strut and spring assembly work
