The RalliTEK Anti Wobble Insert replaces the soft factory rubber insert in your Subaru Crosstrek's automatic transmission mount, tightening up drivetrain movement without the harshness of a solid mount. It reduces the clunk and shunt that builds up as the OEM insert wears, restoring crisp throttle response and a more connected feel under acceleration and deceleration. Choose the Soft Insert for street driving with a minimal increase in noise and vibration, or the Hard Race Insert for track use where firmness matters more than refinement. Fits automatic transmission Crosstrek models only. Canada-wide shipping from Flat 4 Offroad in Calgary.
