Purpose-built rubber: natural and Styrene Butadiene rubber that resists wear and stays stable as it ages for long service life; durometer (hardness) is matched to the vehicle application.
Bonded for strength: Chemlock® bonding agent creates a superior rubber-to-metal bond.
Signs this rear mount may need replacing include a clunk on acceleration, deceleration or shifting, vibration felt at idle, or cracked and separated rubber. Diagnose the cause before replacing.
