The GKTECH Polyurethane diff bushes are a direct replacement of the standard items and ensure that movement of the diff is kept to a minimum within the subframe which is quite common under hard driving conditions.- Polyurethane 80sHA construction- Available to order as front, rear or front and rear kit Front, rear or front and rear? Front only:The front diff bushes are to be used when installing an S14/S15/R33/R34 diff in an S13/R32 subframe. The S14/S15/R33/R34 diffs have bushes on both the front and rear of the diff whereas the S13/R32 diffs do not. You use the original rear diff cover and then to get the front of the diff positioned correctly and then these bushes are to be installed.NOTE: Longer front mount bolts are required when installing an S14/S15/R33/R34 diff in an S13/R32 subframe (20mm longer = 80mm thread length).
