So you tore apart your AAM 11.5 rear axle for a new gear installation and find out the spider gears are worn. No worries, Yukon has you covered. Yukon Gear & Axle spider gear kits feature higher quality materials and better manufacturing techniques than OEM to ensure a longer lasting spider gear set. Kit delivers everything needed for a complete and proper spider gear set replacement.
IMPORTANT FITMENT NOTE:- 11.5" cases and spiders came in two different sizes, with large and small hub sizes on the side gears. Small hub diameter is 1.816" and came in '07 & down GM differentials. Large hub diameter is 2.060" and came in '08 & up GM differentials and all Dodge differentials. This is a universal spider gear kit with adapters to fit either design. The early cross pin shaft included in the kit works with snap ring design carrier only.
