The RalliTEK Anti Wobble Insert replaces the soft factory rubber insert in your Subaru Outback'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. The Outback spans multiple engine and transmission combinations, so select the correct variant below. Fits automatic transmission Outback and Legacy models only. Canada-wide shipping from Flat 4 Offroad in Calgary.
