ISR Performance Solid Differential Mount Bushings - S14/S15 - Gold

The factory rubber diff mounts on the S14 and S15 deflect under load, which is exactly what you don't want when the rear end is trying to put power down. Solid billet and Delrin bushings eliminate the slop, tighten up power delivery, and lock the diff exactly where it should be.

What It Does

Replaces all six factory rubber diff mount bushings with a CNC-machined aluminum and Delrin combination. The Delrin handles the load transfer with minimal flex while the aluminum provides the structural housing. Direct drop-in replacement, no fabrication required. Expect a noticeable increase in driveline harshness, that's the tradeoff for the tighter response.

Fitment

Nissan 240SX S14 (1995 to 1998) and Silvia S15 (1999 to 2002). Direct replacement for the factory rubber pieces.
