- Yukon or Nitro Spool (30 or 40 spline)
- 4.56/4.88/5.13/5.38 thick cut gear
- Master install kit
NOTE:
Solid pinion spacers prevent loosening of the gear setup preload. Solid spacer and shims replace the crush sleeve. It takes a little longer to set up but you won't have to retorque the pinion nut down the road.
