Our SPL SOLID aluminum differential mounting bushings eliminate the stock mushy rubber bushings on the differential pumpkin when adapting J30, Z32 (NA), S14, S15 or Skyline rear differential pumpkins to the S13 rear subframe. These bushings will hold the differential solidly to the subframe, reducing wheel hop and improving power transfer to the ground.
Our SPL SOLID series bushings are precision CNC machined from T6061 billet aluminum for an accurate fit. Includes new mounting bolts.
Note: Stock S13 differentials do not have bushings. These are for a S14, Q45, or a Z32 differential swap.
