Fitment and Application Details
Built for Ford Super Duty trucks, the Rancho RS66555R9 is a front suspension kit for drivers who want a leveled stance without changing the truck’s core suspension layout. This part number, RS66555R9, is listed for 2011-2024 Ford F-250 Super Duty and Ford F-350 Super Duty front applications, with configuration notes that vary by model year.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Issues This Kit Can Address
- Front-end rake on Ford F-250 Super Duty and Ford F-350 Super Duty trucks
- Uneven stance after adding front-end accessories or load
- Need for a 2.5-inch front leveling change
- Front shock replacement during a leveling upgrade
- Ride control concerns when moving to a performance-oriented suspension setup
Installation Notes and Tips
For 2011-2021 Ford F-250 Super Duty and Ford F-350 Super Duty applications, the kit notes that OE radius arms must be used. Review the vehicle’s year-specific fitment before installation, since the included notes differ between 2011-2021 and 2022-2024 trucks. RS66555R9 is a front-position suspension kit only.
Quality Assurance
Rancho lists this as a performance-grade suspension kit and pairs the leveling components with RS9000XL front shocks for a controlled ride on pavement and off-road terrain.
