MuscleRods LS Engine Swap Kit for 1982-2005 Chevy S10 Blazer and GMC S15 Jimmy 2WD
When a Chevy S10 Blazer or GMC S15 Jimmy built between 1982 to 2005 needs LS power this LS Conversion Kit from MuscleRods delivers a fully engineered mounting system that preserves the factory drivetrain angle and avoids common clearance headaches. Precision machined motor and frame brackets align the LS block within the S Series frame rails to limit torsional stress and reduce vibration under load. Installers benefit from direct fit bolt patterns that accept T56 4L60E and 4L80E transmissions without altering the floor or tunnel so interior panels remain intact. A focused layout also delivers proper LH8 oil pan clearance and Corvette style accessory pulley alignment for consistent fluid flow and belt tracking.
Precision CNC Machined Brackets Preserving Drivetrain Geometry
The motor and frame brackets in this LS swap solution are crafted through CNC machining from US steel plate to lock the engine and transmission in the exact factory angle. Maintaining the original driveline orientation reduces torsional stress on the crankshaft and input shaft, which translates into smoother power delivery and reduced vibration under load. These brackets index directly to the S 10 frame's existing bolt holes, eliminating the need for custom welds or trial alignments and ensuring the same precise fit on every vehicle. By holding Corvette style accessory pulleys true to the crank, belt tracking remains consistent and accessory drive components enjoy longer service life.
Engine Bay Packaging for LH8 Oil Pan and Corvette Accessory Drive
This conversion kit is engineered specifically for use with the LH8 oil pan, preserving full sump capacity while avoiding common clearance issues in the confined Blazer and Jimmy engine bays. Short style brackets adapt the Corvette water pump and harmonic balancer to the chassis without trimming the firewall or altering brake booster mounts. The layout steers belt runs clear of steering components and brake lines to prevent rubbing or bind points. With this focus on packaging, oil flow stability is maintained during cornering and hard acceleration, and accessory belt alignment stays true over thousands of miles.
Direct Fit Transmission Crossmember for Major Gearboxes
The included transmission crossmember is predrilled to accept T56, 4L60E and 4L80E units without any modification to the floor or tunnel, so the original interior panels and headliner remain intact. Mounting saddles on reinforced frame rails use factory holes for a rock solid foundation that withstands high torque applications without flex. For less common transmissions, only minor seam flattening is required to clear a pinch weld, making this crossmember adaptable to a wide range of builds. This approach preserves chassis rigidity and cuts installation time by removing the need for custom crossmember fabrication.
Polyurethane Transmission Mount for Reduced NVH and Sharpened Shift Feel
Replacing the stock rubber isolator, the polyurethane transmission mount included in this kit resists deformation from heat and exposure to automotive fluids, keeping drivetrain movement to a minimum. Its firmer compound minimizes lash between gears, which yields crisper shifts and more immediate throttle response. By curbing unwanted movement, vibrations are less likely to travel into the cabin, improving comfort on both daily drives and spirited runs. All necessary spacers and hardware arrive in one hardware pack to streamline the final installation and deliver reliable performance mile after mile.
