ya here. this is out of Hagen article, You will need a ring and pinion retainer sleeve kit. This can be purchased from Hawk Strictly Suzuki or Spidertax. This kit is designed to put a Tracker/kick ring and pinion into a Samurai axle. This kit is a two-piece kit. Since we are putting a Samurai carrier in a Tracker/kick housing, we will only need the barrel from this kit. The barrel is to hold the pins for the locker in place so they do not hit the pinion. Assemble into the Steel housing. lata stu
