Here at Chirco performance we offer several styles of Sand Rail king pins in Link Pin sets, for longer and wider Sand Rail off-road trailing arms we offer our part number 401201 Link Pin that utilizes the standard bushing size but the Link Pin itself is about an inch and a half longer and has a threaded nut on the end to prevent the arm from coming loose on the Link Pin, we do suggest using our bronze off-road racing Link Pin bushings part number 401201B for hard off-road abuse.
