AMT Motorsport Vulcan Motor Mounts – C6 Corvette
The AMT Motorsport Vulcan Motor Mounts are built to replace the factory-style motor mount strategy on a 2005–2013 C6 Corvette when heat, age, and repeated load cycles make mount control a priority. AMT’s design uses two machined 6061 aluminum cups capturing 90 durometer rubber pucks with a center spacer, intended to reduce unwanted engine movement compared to deteriorated stock mounts.
This setup is commonly chosen for C6 street performance builds and track-day cars where throttle transitions, hard launches, and cornering load can expose excessive drivetrain movement. AMT Part Number: 265021. AMT offers Standard and a Race version (3/8 inch shorter than stock) for specific clearance needs.

Why This Brand Leads
- AMT Motorsport designs parts around real track load, heat, and repeatability goals
- Two-piece captured design targets controlled engine positioning under hard use
- In-house manufacturing focus supports consistent tolerances and repeatable builds

What to Expect After Installation / Use
A C6 with performance-oriented motor mounts typically feels more consistent during aggressive throttle transitions and repeated hard driving. Moving from soft or worn mounts to firmer mounts can make NVH more noticeable compared to a comfort-focused daily setup. After installation, follow standard best practice: re-check fasteners after initial heat cycles and periodically if the car is driven hard.
