AMT Motorsport Vulcan Differential Mounts for the C6 Corvette Drivetrain (2005–2013)
The AMT Motorsport Vulcan Differential Mounts are designed to reduce unwanted differential movement in a 2005–2013 C6 Corvette under hard acceleration, braking, and cornering loads. By controlling movement at the differential mounting points, these mounts help the drivetrain feel more consistent when traction and load change quickly. AMT Part Number: 265030.
Unlike simple “solid” solutions, this design uses a captured rubber isolation section inside a two-piece aluminum assembly so the mount can control movement while still managing noise and vibration in performance-oriented street builds and track-day setups.

Why This Brand Leads
- Billet-style construction strategy (machined aluminum parts rather than bent sheet metal assemblies)
- Captured rubber section is designed to resist deformation and extrusion under load
- Hardware and access details are built around repeatable installs and serviceability
Benefits
- Reduces drivetrain “pendulum” movement that can show up in aggressive transitions
- Improves consistency on hard launches and during quick on/off throttle changes
- Helps the rear drivetrain feel more planted in corners when load changes quickly
- Balances control with vibration management through a captured isolation section
What to Expect After Installation / Use
Installation is straightforward for most C6 Corvette owners with basic tools, and the sunk-in fastener design helps with access. After install, expect a drivetrain that feels more consistent under load. Noise and vibration levels can change compared to softer factory rubber mounts, but the isolation section is designed to avoid the harshness that comes with fully solid mounting strategies.
