01Overview
This is the differential mounting bush, in polyurethane.
The diff hangs on rubber from the factory. Once it perishes the whole unit rocks on power, which you feel as a bang on gear changes and slack in the driveline.
90 ShA polyurethane — the yellow SPORT compound. StrongFlex build this grade for tuned and lowered cars: the suspension gets noticeably stiffer, the geometry stops moving under load and the car holds its line when you push it.
Polyurethane takes that movement out. Shifts land cleanly and the drivetrain stops shunting.
Every StrongFlex product ships with the correct grease for fitting.

Fitting notes
01A car takes 2. This listing is 1 piece, so order accordingly.
02Replace them in pairs. A new bush on one side and a tired one on the other leaves the axle sitting crooked.
03Grease the bush surfaces on assembly. StrongFlex include the grease.
