The GKTECH Polyurethane transmission mount is a direct replacement of the standard item and helps reduce engine and transmission movement and get power to the ground. Particularly useful in a drift car where the car is off and on the throttle although all forms of motorsport will see an improvement in feel of the car but without the drastic increase in vibrations that the solid mounts see. - 80ShA Polyurethane - Fits all RWD KA24, SR20, RB20 and RB25's - Replacement part for Nissan part numbers: 11320-35f01, 11320-41L03, 11320-65F01, 11320-85F01, 11320-70T01 - Replacement part for Nismo part numbers: 11320-RS541, 11320-RS585, 11320-RSR40 - Fits the Gktech Z33 350z/ Z34 370z Crossmember with slight shaving to one side Vehicle Compatibility: R32 SKYLINE GTS-T S13 CA18 240SX HATCH S13 CA18 240SX/SILVIA S13 SR20 240SX HATCH S13 SR20 240SX/SILVIA S14 240SX/SILVIA S15 SILVIA
