"This unique new concept in protection guards the shock clevis and shock linkage from rock damage and enables the linkage to glide over logs and boulders. Without the Slavens Link Skid, the shock clevis will catch on logs and stop the bike or throw the rider forward. Because the clevis and linkage extends well below the swingarm, it is very susceptible to expensive damage. The Slavens Xtreme Link Skid is for those that ride rocky conditions and demand the best coverage possible. The new loop design bottom plate gives added protection and durability."
