C5 Corvette HINSON Urethane Engine Mounts (3/8" Shorter) - Corvette C5 C6 GTO

Hinson Motorsports Shorter Urethane Engine Mounts – Precision. Performance. Clearance.

Eliminate drivetrain movement while optimizing fitment with Hinson Motorsports Shorter Urethane Engine Mounts (Part #4051). Designed for high-performance V8 applications, these mounts provide the perfect balance between engine control and vibration dampening—ideal for both daily-driven street cars and track-ready machines.

Built with the same high-quality medium-durometer urethane as our standard mounts (Part #4050), this shorter version is specifically engineered to resolve clearance issues in high-performance builds. Whether you’re running a FAST/MSD intake on your Corvette or need additional supercharger hood clearance on your GTO, these mounts ensure a proper fit without sacrificing performance.

Featuring an interlocking stainless steel core, these mounts allow the engine to “float” within the urethane, reducing drivetrain movement while minimizing excessive NVH (noise, vibration, harshness). The result? Sharper throttle response, more precise shifts, and improved power transfer—all while maintaining comfort for street driving.

Why Choose the Shorter Mounts?

? Corvette Cowl Clearance – Ideal for setups running a FAST, MSD, or other large intake.
? GTO Steering Shaft-to-Header Clearance – Prevents interference in tight engine bay configurations.
? Additional Hood Clearance for Supercharger Installations on Corvette & GTO.
