The adjusted compression and rebound options allow you to dial that in for your own style and preferences. 350# spring great for aggressive MX style riding. 100mm of travel (22mm bump stop). Installation Note - Please inspect your OEM shock bolts, linkage bolts, and bushings/bearings. If they are worn or bent your suspension will not function properly and it will cause excessive wear.
Also be sure all linkage bolts stay torqued to spec. These are common issues we see that can easily be avoided, they ensure a smooth feel and long life out of your rear shock.
