- Supports and isolates: cradles the transmission and dampens vibration to limit movement and noise.
- Purpose-built rubber: only natural and Styrene Butadiene rubber, which resists wear and stays stable as it ages for long service life.
- Strong bond: a Chemlock® bonding agent creates a superior rubber-to-metal bond.
- Application-tuned: rubber is manufactured to a specific durometer (hardness) based on the vehicle application, and is engineered to OE standards using a CAD/CAM process.
Any included fasteners are hardened steel, heat-treated Grade 5 bolts. Worn signs include vibration at idle, and clunk or thump on acceleration, deceleration, or shifting as the rubber cracks or separates.
