RanchoThe all-new, fully adjustable Rancho is available for most domestic and import light trucks and SUVs. The RS9000X allows drivers to dial in the ride, and they feature a tri-tube (reserve/intermediate/primary) design that yields maximum fluid area and ensures exceptional performance under a full range of load and temperature conditions. The shock significantly increases the precision of tunable compression and rebound damping through nine metered settings. The RS9000X also can be adjusted on the fly through an updated in-cab remote control kit. The self-adjusting shock combines a nitrogen-charged, twin-tube design and a patented Reflex valve.

This rear system comes complete with shocks and eliminates all the guesswork.

AdjustableFirestoneFirestone Ride-Rite and Sport-Rite air spring suspension systems provide increased ride comfort and superb handling. Ride-Rite uses double-convoluted air springs for leveling and load carrying capacities between 3,000 and 5,000 pounds per set. Sport-Rite uses a new-technology tapered air spring for supporting as much as 3,000 pounds per set. Both style systems dramatically improve ride and load-carrying capacities. They mount between the frame and the suspension and are easily installed in less than two hours. Applications are available for most vehicles.
