LS Engine Mounts for 1984-1991 Chevy Corvette
For builders tackling an LS engine swap in a C4 Corvette the 1984-1991 Corvette LS Engine Mounts deliver precise alignment and secure fit without any chassis trimming. Featuring heavy gauge steel plates and durable polyurethane bushings these mounts absorb vibration and reduce engine movement under load. Installation requires no tunnel changes and includes a complete hardware kit with clear step by step instructions to preserve the Corvette's original handling characteristics.
Precision Alignment for C4 Corvette LS Swaps
These engine mounts are machined to the exact factory dimensions for 1984 to 1991 Corvette frames, ensuring the LS engine sits at the ideal drivetrain angle without any chassis trimming. By preserving the original mounting points, they maintain the Corvette's engineered weight distribution and suspension geometry. This precise fit-up not only saves time during installation but also upholds the vehicle's handling balance under acceleration, cornering, and braking. Clear step-by-step instructions guide you through bolt-in attachment, eliminating guesswork and preserving the car's structural integrity.
Heavy Gauge Steel and Polyurethane Bushing Design
The core structure employs heavy gauge steel plates that resist flex and torque forces generated by high-output LS engines. Welded with TIG precision, these mounts form a rigid cradle that keeps the powerplant firmly in place under all driving conditions. Integrated polyurethane bushings absorb and dissipate vibration without compromising rigidity, reducing drivetrain lash and fatigue over time. This combination delivers long-term durability and consistent alignment even in spirited driving or track use.
Seamless Transmission Integration with Vibration Isolation
Specifically engineered to accept LS engines and OE 4L60E or 4L80E transmissions, these mounts require no tunnel modifications and bolt directly into the factory transmission crossmember. The included hardware kit and illustrated instructions ensure a straightforward swap, while the polyurethane isolators minimize engine movement and noise. By controlling NVH at the source, you preserve a quiet cockpit and the Corvette's signature ride quality. American-made craftsmanship underscores the reliability and performance you expect from a precision mounting solution.
