A-Premium Engine & Transmission Mount Kit, Set of 4 for 2003–2008 Corolla/Matrix/Vibe — OEM-fit, Vibration-Reducing

A-Premium's 4-piece mount kit securely supports the engine and transmission for 2003–2008 Toyota Corolla, Matrix and Pontiac Vibe 1.8L FWD automatics, reducing vibration and road noise.

If your vehicle shakes at idle, shutters during acceleration, or transmits drivetrain clunks into the cabin, worn mounts are often the culprit. This kit includes the front, front-right, rear engine mounts and the transmission mount engineered to match the OEM mounting points for a straightforward replacement. Built from reinforced materials, the set restores proper alignment between the engine and transmission while minimizing harshness for a quieter ride.

How does installing this kit improve driving comfort and drivetrain performance?

New mounts reestablish secure engine and transmission mounting points, limiting excessive movement under load and reducing the transfer of vibration into the cabin. You’ll notice fewer bangs during gear changes and less vibration at idle or under acceleration. Proper mounts also keep driveline components aligned, which reduces stress on other parts like axles and exhaust hangers.

• Reduces cabin noise and pedal-to-seat vibration
• Prevents engine/transmission misalignment under torque
• Helps protect related components from premature wear

Are these mounts durable and what warranty is included?

The mounts are made from reinforced rubber bonded to metal housings to withstand typical engine torque and road conditions. A-Premium backs the kit with a one-year unlimited-mileage guarantee for manufacturing defects, giving added confidence after installation. Proper installation and vehicle use will affect longevity, so inspect mounts periodically.

• Constructed from durable rubber and metal materials
