the most customizable adjustable shocks are the RC2 from fox. They are sick, you get to set rebound, and stroke, so your ski shocks preform how you want from start, adjust through the stroke, and then adjust how it finishes.... great for all types of riding styles! add in the Toms Emotion skid with fox and your really able to dial your sled to handle exactly how you want. plus this skid eliminates the coil springs so its a little lighter and full air ride. smooth adjustable, and epic..... if your upgrading suspension then this is the way!
