Whiteline Performance Rear Axle Differential Mount - Front Bushing Kit - 350Z / 370Z
W93189
Over time, the factory front differential mount bushings soften and allow the diff to shift under load, dulling throttle response, introducing driveline vibration, and causing inconsistent power delivery. The Whiteline W93189 solves this without removing the factory bushing, four synthetic elastomer inserts simply fit inside the existing rubber to eliminate the compliance that causes the problem.
Engineered specifically for the rear differential front mount on the 350Z, 370Z, and the full Z/Skyline/Stagea family, these inserts work with your factory bushings rather than replacing them. Whiteline's synthetic elastomer compound fills the compliance void in the OEM rubber, maintaining correct pinion angles and improving power transfer, backed by a lifetime warranty.
