A Subaru Outback's factory automatic transmission mount uses a soft rubber insert that wears over time, letting the drivetrain shift and clunk under acceleration and deceleration. RalliTEK's Anti Wobble Insert replaces it, tightening up that movement without the harshness of a solid mount. Choose the Soft Insert for street driving with minimal added noise, or the Hard Race Insert where firmness matters more than refinement. The Outback spans multiple engine and transmission combinations, so select the correct variant below. Automatic transmission Outback and Legacy models only.
