PERRIN Rear shifter bushings help eliminate any loose and sloppy feel during gear changes! Give your shifter a feeling of precision not found with stock bushings! The PERRIN Rear Shifter Bushing removes the soft rubber bushing on the back of the shifter rod. This vital connection point joins the shifter mechanism to the chassis. Installing the stiffer PERRIN Rear Shifter bushing makes the shifter feel even more connected to your transmission. The PERRIN Rear Shifter bushing is constructed from stiff 88a durometer, polyurethane. This material is flexible enough to allow for normal drivetrain movement, but stiff enough to eliminate the large amounts of deflection from the stock part.
