Vulcan Motor Mounts for the C5 Corvette
The AMT Motorsport Vulcan Motor Mounts are designed for a 1997–2004 C5 Corvette to help reduce unwanted drivetrain movement under load while keeping the mounting system durable for repeated heat and hard driving. This kit uses billet aluminum cups with vulcanized rubber puck isolators to support a more controlled engine position than worn factory mounts.
These mounts are commonly chosen when a C5 owner wants a more consistent feel during throttle transitions and hard acceleration.
