Complete MuscleRods LS Engine Swap Kit for 1963-1967 Chevy Corvette C2 Stingray
For C2 Corvette owners planning an LS powertrain swap, the MuscleRods 1963-1967 Corvette LS Conversion Kit provides precision engineered mounts that ensure accurate drivetrain geometry and eliminate transmission tunnel modifications. Its precision cut steel brackets tie directly into the factory frame rails holding the LS engine in the exact position required for a smooth vibration free ride. Included transmission crossmember hardware covers both 4L60E and 4L80E bolt patterns without tunnel or steering changes. By clearing power assist steering pumps and high clearance or F Body oil pans this kit lets builders install most Gen III and Gen IV LS engines without extra fabrication.
Precision Engine Mount Alignment for LS Powertrains in C2 Stingray
The conversion kit's engine brackets are laser cut from thick steel plate to align with the Corvette's factory frame rails. This attention to geometry maintains the original drivetrain angle and delivers a vibration free ride by minimizing uneven loading on the mounts. By securing the LS motor in the exact position required, the system reduces flex under load and preserves steering feedback for more consistent handling. Installers benefit from exact hole patterns that eliminate trial fitting and avoid altering the tunnel or body panels. The use of welded brackets paired with precision cut mounting points reduces installation errors and provides repeated accuracy when servicing or replacing engine components.
Versatile Transmission Crossmember with Modular Spacer System
The heavy gauge crossmember bracket accommodates both 4L60E and 4L80E transmissions using the included spacers for proper bolt pattern alignment. This modular system secures the transmission without cutting or reshaping the tunnel and works with factory or aftermarket steering configurations. Spacer placement also creates clearance for high clearance and F Body style oil pans, letting builders choose any Gen III or Gen IV LS engine without additional fabrication. The crossmember delivers a straightforward retrofit and maintains factory clearance for steering boxes and power assist components. With its bolt on approach, the crossmember preserves the Corvette's original undercarriage appearance while accommodating modern driveline components.
Resilient Polyurethane Transmission Mount for Reduced Noise and Harshness
The polyurethane insert in the transmission mount balances rigidity and shock absorption to filter driveline vibrations before they reach the chassis. This material resists oil and coolant exposure and retains properties through repeated heat cycles in the engine bay. When installed into the crossmember, it dampens harshness and lowers cabin noise levels for a more comfortable driving experience. The mount seats precisely into the bracket, allowing a clean fit with no tunnel modifications or additional adapters. Technicians will value the mount's resistance to deformation, which helps maintain consistent alignment even under aggressive acceleration or braking.
American Craftsmanship from Design to Delivery
All brackets and mounts are engineered and manufactured in the United States, ensuring strict quality control and consistent performance across each kit. Laser cutting and CNC bending techniques produce precise fitment for all Corvette frames built from 1963 to 1967. Domestic sourcing of materials guarantees reliable mechanical properties and simplifies replacement if needed. Each kit is backed by a thorough inspection process so builders receive parts that integrate seamlessly with the Corvette chassis without secondary machining. By concentrating manufacturing in local facilities, lead times are reduced and support remains accessible for both professional shops and home builders.
