C5 Corvette AMT Motorsport Double Barrel Differential Mount (1997-2004)

AMT Motorsport Double Barrel Differential Mount for the C5 Corvette Drivetrain (1997–2004)

The AMT Motorsport Double Barrel Differential Mount is designed to reduce unwanted differential movement in a 1997–2004 C5 Corvette under acceleration, braking, and cornering loads. By controlling the differential at its mounting points, this mount helps the rear drivetrain feel more consistent when the car is driven hard. AMT Part Number: 265032.

This mount uses a dual-pivot “double barrel” design with rubber and steel internal elements to resist side-to-side and front-to-back twisting while still managing vibration compared to fully solid mounting strategies.

Why This Brand Leads

• Purpose-built mount strategy for C5 drivetrain control rather than universal “one-size” hardware
• Dual-pivot architecture is designed to resist twist in multiple directions under load
• Machined construction and hardware details are built around repeatable installs and serviceability

Benefits

• Reduces differential “pendulum” movement that can show up during aggressive transitions
• Helps launches and throttle changes feel more consistent by controlling drivetrain motion
• Improves repeatability in corners by resisting twist at the differential mount point
• Balances control with vibration management through rubber and steel internal elements

What to Expect After Installation / Use

After installation, the rear drivetrain typically feels more controlled under load, especially in quick on/off throttle transitions. Noise and vibration levels can change compared to softer factory rubber mounts, but the internal isolation elements are designed to avoid the harshness associated with fully solid mounts.
