AMT Motorsport Vulcan Motor Mounts for C5 Corvette

The AMT Motorsport Vulcan Motor Mounts, part number 265020, fit 1997–2004 C5 Corvette Base Coupe, Convertible, Fixed Roof Coupe, and Z06 models with the LS1 or LS6 5.7L engine. Sold as a pair, these performance motor mounts replace the factory oil-filled mounts with machined aluminum cups and heat-resistant 90-durometer rubber isolators to help control unwanted engine movement during acceleration, shifting, cornering, and track use. Choose the Standard configuration for most C5 Corvettes or the 3/8-inch-shorter Race configuration only when additional engine or intake clearance is specifically required.

Benefits

Replaces factory oil-filled motor mounts that can deteriorate, crack, and leak
Helps reduce unwanted engine movement during acceleration, shifting, and cornering
Provides more consistent drivetrain control during spirited street and track driving
Uses heat-resistant vulcanized rubber rather than standard polyurethane isolators
Captured two-piece construction helps keep the engine securely positioned under load
Provides firmer control than worn factory mounts without using a completely solid design
Includes Grade 10 mounting hardware and installation instructions

Important Notes

The Standard configuration is the correct choice for most C5 Corvette installations.
The Race configuration is 3/8 inch shorter than the factory mounts and should be selected only when additional clearance is specifically required.
The shorter Race mounts can provide additional clearance for installations such as a FAST 102 intake.
Race mounts may create clearance concerns around the crank damper, oil pan, transverse leaf spring, headers, or other nearby components.
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 included installation instructions.

Use Overview

Factory C5 Corvette motor mounts use soft oil-filled rubber to isolate engine vibration. Heat, age, and repeated drivetrain movement can cause the 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 C5 Corvette Motor Mounts?

AMT Motorsport Vulcan Motor Mounts combine machined 6061 aluminum components with heat-resistant 90-durometer rubber to provide firmer engine control without using a completely solid mount. The Standard and Race configurations allow C5 Corvette owners to choose factory-replacement height or additional clearance for a specialized engine setup, while included Grade 10 hardware and a lifetime replacement guarantee support long-term performance use.

Frequently Asked Questions

Do AMT Motorsport Vulcan Motor Mounts fit every C5 Corvette model?

Yes. AMT Motorsport Vulcan Motor Mounts fit 1997–2004 C5 Corvette Base Coupe, Convertible, Fixed Roof Coupe, and Z06 models with the LS1 or LS6 5.7L engine.

Do AMT Motorsport Vulcan Motor Mounts fit a C5 Corvette Z06?

Yes. These motor mounts fit 2001–2004 C5 Corvette Z06 models with the LS6 5.7L engine, as well as C5 Corvettes equipped with the LS1 5.7L engine.

What is the difference between Standard and Race AMT motor mounts for a C5 Corvette?

The Standard version maintains the factory motor-mount height and is correct for most C5 Corvette installations. The Race version positions the engine 3/8 inch lower and should be selected only when a specific engine or intake setup requires the additional clearance.

Do I need the shorter Race motor mounts for a FAST 102 intake on a C5 Corvette?

The 3/8-inch-shorter Race mounts can provide additional clearance for a FAST 102 intake installation. Before ordering, verify clearance around the crank damper, oil pan, transverse leaf spring, headers, and other nearby components.

What are the symptoms of worn factory motor mounts on a C5 Corvette?

Common signs include leaking fluid from the factory mounts, excessive engine movement, clunking during acceleration or shifting, and an inconsistent drivetrain feel when getting on or off the throttle.
