Shock Therapy Can-Am Defender Spring KitCan Am Defender spring kits are here! Rigorously tested and perfected over the past few months, our spring kit for the Can Am Defender is incredible! The springs in this kit are made in the USA from the highest grade CrSi material (which is more expensive than the other springs but are exactly the intended spring rate every time and they dont fade). This spring system will give you a smoother more plush ride than stock and better bottom out resistance
