AMT Motorsport Vulcan Motor Mounts for C6 Corvette
The AMT Motorsport Vulcan Motor Mounts, part number 265020, fit 2005–2013 C6 Corvette Base, Grand Sport, Z06, ZR1, and 427 Convertible models with the LS2, LS3, LS7, or LS9 engine. These performance motor mounts replace the factory oil-filled mounts with machined aluminum cups and heat-resistant vulcanized rubber to help control unwanted engine movement during acceleration, shifting, cornering, and track use. Choose the standard-height version for normal replacement installations or the 3/8-inch-shorter Race version when additional engine and intake clearance is specifically required.

Important Notes
- The Standard version is the correct choice for most C6 Corvette installations.
- The Race version is 3/8 inch shorter than the factory mount and should be selected only when the additional clearance is specifically required.
- The shorter Race mounts were developed to help provide clearance for installations such as a FAST 102 intake.
- Race mounts may create clearance concerns around the crank damper, oil pan, transverse leaf spring, or other components. Verify the complete installation before ordering.
- These mounts are substantially firmer than the factory oil-filled mounts and may increase engine sound, vibration, and harshness inside the Corvette.
- Installation may require moving or removing headers or exhaust components to access the engine-mount brackets.
- Support the engine properly and follow the supplied AMT Motorsport installation instructions.

Use Overview
Factory C6 Corvette motor mounts use soft oil-filled rubber to isolate engine vibration. Heat, age, and repeated drivetrain movement can cause those mounts to soften, crack, or leak, allowing the engine to move excessively under load. AMT Motorsport Vulcan Motor Mounts provide a firmer captured-rubber design for Corvette owners who want better engine control during hard acceleration, fast shifts, autocross, drag racing, road-course driving, or spirited street use.
Why Buy These AMT Motorsport C6 Corvette Motor Mounts?
AMT Motorsport Vulcan Motor Mounts combine machined 6061 aluminum components with heat-resistant 90-durometer vulcanized rubber to deliver firmer engine control without using a completely solid mount. The Standard and Race configurations allow C6 Corvette owners to choose factory replacement height or additional clearance for a specialized engine setup, while included mounting hardware and AMT Motorsport’s lifetime replacement guarantee support long-term performance use.
