Packed with innovative features, Rancho's RS5000X shocks deliver improved overall on and off-road handling and performance thanks to Rancho's exclusive Cross Tuned technology. Developed by the ride engineers at Rancho, this unique and exclusive rebound valving system and advanced compression phase of the shock absorber is at the heart of the RS5000X. Not just for ride comfort, shocks and struts are a key part of your vehicle's suspension system. Designed to maintain vertical loads placed up on the tires, shocks and struts help ensure consistent tire-to-road contact. This is important because if your car doesn't maintain firm contact with the road or trail, steering, handling and braking can all be affected. Shocks and struts also help maintain a balanced ride by providing resistance to vehicle bounce, roll, and sway, as well as brake dive and acceleration squat. Performance shocks and struts can help your vehicle handle the impacts, bumps and rough terrain that comes with off-roading or rock crawling. Replacing stock shocks with aftermarket shocks comes with many advantages. Do you drive a truck or SUV that you take on the trail for a day of off-roading or rock crawling? Have you made other improvements to your rig like installing larger tires or adding a suspension lift kit? If you answered yes to either of these questions, you may want to replace the factory shocks and struts on your vehicle with performance shocks. Making this change may improve the ride and handling of your rig.
