Complete MuscleRods LS Engine Swap Kit for 1982-2005 S10 Blazer/S15 Jimmy 2WD
The 1982 to 2005 S10 Blazer 2WD LS Conversion Kit simplifies swapping an LS engine into the S-Series chassis by providing a complete mounting solution. Precisely machined motor and frame brackets position the block at factory driveline angle, while the crossmember accepts T56, 4L60E and 4L80E transmissions without altering floor or tunnel. Installers benefit from a direct installation that preserves firewall and brake booster locations, ensures LH8 oil pan clearance and aligns Corvette accessory pulleys for reliable fluid flow and belt tracking. Made in the USA from US steel plate, this MuscleRods kit fits 1982 to 2005 Chevy S10 Blazer and GMC S15 Jimmy 2WD models for a precise powertrain swap.
Precision Machined Brackets for Accurate LS Engine Positioning
The motor and frame brackets are CNC machined from US steel plate to align the LS block at the factory driveline angle within the S series frame rails. This high tolerance machining reduces torsional stress on both crankshaft and transmission input shaft, yielding smoother power delivery and minimal vibration under load. Each bracket indexes to existing bolt holes, eliminating custom fitting and ensuring consistent alignment on every chassis. By preserving the original accessory pulley orientation, belt tracking remains stable and component wear is reduced over long service intervals.
Optimized Engine Bay Packaging for LH8 Oil Pan and Accessory Alignment
This kit addresses engine bay clearance by accommodating the LH8 oil pan without trimming the firewall or relocating the brake booster assembly. Short style mounting arms adapt Corvette water pump and harmonic balancer components to fit within the confined space of the S series frame. Routed belt paths avoid steering linkage and brake lines, preventing potential rubbing or bind points. With fluid flow stability maintained during cornering and rapid acceleration, lubrication remains consistent and accessory belts hold true to their pulleys over thousands of miles.
Versatile Transmission Crossmember Accepting Multiple Gearbox Options
The supplied crossmember accepts T56, 4L60E and 4L80E transmissions directly to the stock floor pan and tunnel layout. Reinforced saddles bolt to factory frame holes, delivering a rigid foundation capable of withstanding high torque without flex. For less common gearboxes, minor seam flattening clears pinch welds without major alterations. This design preserves interior panels intact and significantly cuts installation time by avoiding custom fabrication for each build.
Polyurethane Transmission Mount and Hardware Pack for Lasting Stability
Replacing the stock isolator, the polyurethane transmission mount resists deformation from heat and fluid exposure, limiting drivetrain movement under heavy loads. Its firmer compound reduces lash in the driveline, resulting in crisper shifting and more direct throttle response. By curbing vibration transfer into the cabin, driver comfort improves during both daily use and spirited driving. All required spacers and fasteners are included in a single hardware kit, streamlining assembly and ensuring reliable performance mile after mile.
