These 2.5” Radflo air shocks are specifically designed and tuned to give you the best stability, performance, and ride quality on your rock buggy. The single rebound bypass tube gives you a comfortable ride but also allows the shock to have extremely stiff rebound valving to prevent unloading. Ideal for buggies in the 3000-3700 lbs range. Sold in a set with two 16” and two 18” shocks. Shipping included in price.
