Complete MuscleRods LS Engine Swap Kit for 1973-1987 C-10/C-15 and 1973-1991 2WD Blazer/Jimmy
For builders installing an LS V8 into 1973 to 1987 Chevrolet C10 and GMC C15 trucks or 1973 to 1991 two wheel drive Blazer and Jimmy, the 1973-1987 2WD GM Truck LS Conversion Kit solves alignment and fitment challenges from the start. By locking the crank centerline at the stock frame angle, it preserves driveline geometry and maintains proper drivetrain angle to reduce vibration. The kit includes laser cut steel motor mounts, precision frame brackets, a transmission crossmember for T56, 4L60E and 4L80E gearboxes, a polyurethane mount and full hardware pack that bolt to factory openings for oil pan clearance up to four inches tall without modifying the floor pan.
Precision Fitment and Drivetrain Stability
The 1973 through 1987 2WD GM Truck LS Conversion Kit delivers an exact engine position that matches the original mounting points of classic trucks. By preserving the factory tilt, it minimizes driveline vibration and torque steer. Engine mounts bolt directly to MuscleRods crossmember brackets to ensure precise LS placement and correct angle between the crank and driveshaft. This focus on geometry prevents binding during acceleration and reduces wear on universal joints.
Transmission Compatibility and Tunnel Integration
This kit is engineered to accept T56 transmissions as well as 4L60E and 4L80E units without altering the truck's transmission tunnel. Tunnel geometry remains factory stock so body panels and interior trim fit seamlessly. The bracket design offers a direct install for each listed transmission, removing the need for custom brackets or notch work. The result is a time saving install that retains structural integrity and factory appearance.
Enhanced Clearance and Vintage Appearance
Optimized for high clearance oil pan installations, the conversion bracket set sits the LS slightly lower than many kits to clear aftermarket pans and sump extensions while maintaining adequate ground clearance. This placement avoids contact during steep angles or off road excursions. Despite modern powertrain components, the visible mounting surface and supply lines tuck neatly under the stock frame rails, preserving the classic truck look that enthusiasts demand.
American Craftsmanship for Lasting Quality
Proudly made in the USA, the components are formed from thick steel plate and fully powder coated to resist corrosion. Each bracket undergoes precision laser cutting and robotic welding for consistent fit and repeatable strength. By integrating with MuscleRods components, the kit maintains correct height and reduces the need for adjustment shims. Quality certification ensures each bracket set performs reliably under heavy loads and spirited driving.
