AMT Motorsport Double Barrel Differential Mount for C5 Corvette
The AMT Motorsport Double Barrel Differential Mount, part number 265032, fits all 1997–2004 C5 Corvette models, including Base Coupe, Convertible, Fixed Roof Coupe, and Z06 with the LS1 or LS6 5.7L engine. Designed for performance street driving, autocross, drag racing, and track use, its dual-pivot construction helps control side-to-side twisting and front-to-back drivetrain movement while rubber and steel internal elements provide more vibration isolation than a fully solid differential mount.

Important Notes
- This is a performance-oriented differential mount and may transmit more drivetrain sound or vibration than the softer factory rubber mount.
- The mount is not fully solid; rubber and steel internal elements help manage vibration while controlling drivetrain movement.
- Inspect the surrounding differential, transmission, torque-tube, and engine mounts during installation for wear or damage.
- AMT Motorsport recommends pairing this mount with properly functioning engine mounts for balanced drivetrain control.
- Professional installation is recommended if you are not experienced with Corvette drivetrain and suspension components.

Use Overview
The factory C5 Corvette differential mount prioritizes low noise and vibration for everyday street use. During aggressive acceleration, braking, or cornering, the drivetrain can move against that softer rubber mounting structure. The AMT Motorsport Double Barrel Differential Mount uses two reinforced pivot points to limit that movement, helping the rear drivetrain remain more controlled during launches, rapid throttle changes, autocross runs, and track sessions.
What Corvette Customers Say
C5 Corvette owners using the AMT Motorsport Double Barrel Differential Mount commonly describe a more direct drivetrain feel, cleaner throttle transitions, and greater confidence in the rear of the car during performance driving. Because it is stiffer than the factory mount, some owners also notice additional drivetrain sound, making the upgrade best suited to drivers who value improved control over factory-level isolation.
Why Buy This AMT Motorsport C5 Corvette Differential Mount?
The Double Barrel Differential Mount is designed specifically for the C5 Corvette rather than adapted from a universal drivetrain mount. Its dual-pivot layout, machined 6061-T6 aluminum construction, rubber and steel internal elements, lightweight design, and included performance-grade hardware create a balanced upgrade for Corvette owners who want better drivetrain control without moving to a completely solid mount.
