Developed with the off-road enthusiast in mind, the NEW ORV Suspension program from Rugged Ridge gives you the ultimate in both off-road and on-road handling performance. Our staff of off-road experts has created a suspension program using only the finest materials and components. Each ORV Kit includes component parts that work in unison to provide the ride you are looking for. Whether you are on the street or on the trail, the ORV suspension line has you covered! All springs are made of ductile iron (memory metal) and are shot-peaned for additional strength. By shot-peaning the leafs before assembly, you are assured that the leaf springs will not sag over time. All shocks are Nitro charged with self-adjusting valving for a smoother ride on and off the road.
