MuscleRods LS Engine Swap Kit for 1963-1967 Chevy Corvette C2 Stingray
When fitting a modern LS motor into a classic C2 Corvette, precise placement is key to maintain handling and avoid tunnel modifications. With the 1963-1967 Corvette LS Conversion Kit, you gain a set of laser cut steel brackets and crossmember spacers that tie directly into the frame rails to preserve drivetrain geometry. Beyond ensuring proper alignment for both 4L60E and 4L80E transmissions, this design also clears high clearance and F Body oil pans. Installers will find factory steering layouts remain intact and pre drilled hole patterns streamline installation, saving hours in the garage.
Precision Fit Brackets for Drivetrain Geometry
The kit's engine and transmission brackets are laser cut from thick domestic steel and welded with exacting tolerances to match the 1963–1967 Corvette frame rails. This precision fit preserves the factory drivetrain angle, preventing stress on mounts and ensuring a vibration free ride under acceleration. With predrilled hole patterns, installers avoid trial fitting and eliminate the need for transmission tunnel alterations. Maintaining the original drivetrain alignment also safeguards steering feel and handling balance so the Stingray responds exactly as designed.
Adaptive Crossmember Spacer Layout
The transmission crossmember bracket features a modular spacer system that aligns bolt patterns for both 4L60E and 4L80E gearboxes without reshaping the frame tunnel. Builders can choose between factory style oil pans or F-Body units and still clear the pan rail, thanks to adjustable spacer positions. This design keeps the factory steering assembly intact, avoiding rerouting or fabrication of power assist and manual linkages. The bolt on installation reduces fitment uncertainty and cuts hours of garage work into straightforward steps.
Polyurethane Transmission Mount for Smooth Operation
A dedicated polyurethane insert in the transmission mount strikes the right balance of rigidity and damping to block driveline shock from reaching the chassis. This material resists oil and coolant exposure while holding shape through repeated heat cycles in the engine bay. By filtering harsh vibrations, it lowers noise and enhances cabin comfort without compromising clutch or throttle response. Durable against deformation during aggressive launches, the mount ensures alignment remains consistent mile after mile.
Domestic Manufacturing Ensuring Reliable Fitment
Every bracket, spacer and mount in this Corvette conversion kit is engineered and produced in the United States under strict quality control protocols. Laser cutting and CNC bending deliver consistent dimensions for every C2 frame built from 1963 through 1967, eliminating the need for secondary modifications. Sourced from American mills, the steel retains predictable mechanical properties and weld behavior. Rigorous in-house inspection means builders receive a seamless install experience and access to responsive local support.
