MuscleRods LS Engine Swap Kit for 1982-2005 Chevy S10 Blazer and GMC S15 Jimmy 2WD
From the first bolt-up the 1982-2005 S-10 Blazer 2WD LS Conversion Kit puts an LS engine into a Chevy S10 Blazer or GMC S15 Jimmy two wheel drive chassis with perfect positioning and reliable oil pan clearance. It uses precision machined motor and frame mounts to preserve the factory angle and guides Corvette style accessory belts into exact alignment. Offering a direct fit installation that accepts T56, 4L60E and 4L80E transmissions without modifying the floor, it safeguards structural integrity and cuts down on custom fabrication steps.
Precision Machined Motor and Frame Brackets Maintaining Drivetrain Geometry
The kit's motor and frame brackets are CNC machined from US steel plate to position the LS engine at the factory angle within the S Series frame rails. By preserving the original drivetrain geometry, torsional stress on the crankshaft and transmission input shaft is minimized, reducing vibration and gear lash under load. Accurate indexing to existing bolt holes eliminates the need for trial fitting or custom welds, which streamlines the assembly process and ensures repeatable results on every chassis. This precise fit also aligns Corvette style accessory pulleys with the engine's water pump and alternator, preventing premature belt wear and guaranteeing consistent accessory operation over time.
LH8 Oil Pan Clearance and Short Accessory Drive Integration
This conversion solution is engineered for use with the LH8 oil pan, delivering full sump capacity and reliable oil pickup even during spirited driving. Custom brackets adapt the Corvette balancer and water pump to the confined engine bay of the S10 Blazer and S15 Jimmy models produced from 1982 through 2005, maintaining correct belt path without firewall trimming or extended pickup tubes. The careful layout avoids interference with the brake booster and steering components, eliminating common clearance issues that can lead to leaks or throttle body bind. With true attention to packaging detail, the kit provides continuous oil flow and accessory drive alignment in daily or performance use.
Direct-Fit Transmission Support Without Tunnel Modification
The transmission crossmember in this kit accepts T56, 4L60E, and 4L80E units without altering the floor or tunnel in the chassis. Mounting points are pre-located on reinforced frame saddles, so installers simply bolt the assembly into place using original holes. The result is preserved interior sheet metal and headliner fit while maintaining chassis rigidity in high torque applications. Should builders choose alternative transmissions, minor seam flattening is all that is required, making this component a versatile foundation for both street and track drivetrain setups.
Polyurethane Transmission Mount Enhancing Vibration Damping
Replacing the factory rubber isolator, the included polyurethane transmission mount resists deformation under heat and exposure to automotive fluids. This resilience limits drivetrain movement and reduces lash, which sharpens shift feel and prevents binding during rapid acceleration or shifting. The firmer mount support also curbs unwanted vibration from entering the cabin, improving comfort without sacrificing durability. All necessary spacers and hardware are supplied so the mount installs in minutes, delivering measurable NVH benefits throughout the engine's RPM range.
