There are several kit options, please check if your differential uses this type of gear before ordering! This will only fit differentials with six mounting holes. OEM 10/36 Rear Differential Gear Kit Gear and pinion kit. The gears are straight cut as shown in the picture. Complete with high quality aftermarket bearings and dual lip axle seals. This kit should be installed by an experienced technician. Gear spacers are included, since the gears will need to be adjusted in your applications, the gear spacers must remain the same. Note: O-rings are not included in the kit, this is a cost saving measure as they are typically reusable. Open up the differential! Check for two bearings (one on each side) on the ring gear. If you only have two, proceed to the next measurement. Measure the outside diameter of the axle seals! They should be close to 1 3/4 (47mm) To further check the fit you can measure the pinion guide shaft, it should be 9/16 (14mm). This is very clear in the pictures. Please take the time to measure the parts before purchasing, this will save time and restocking costs.
