MuscleRods LS Swap Kit for 1988-1998 GM C1500 and 1992-1999 Tahoe/Yukon 2WD
Installing an LS engine into your 1988 to 1998 two wheel drive C1500 or Tahoe or Yukon often stalls builds with odd angles and tight clearances. MuscleRods designed the 1988 to 1998 2WD GM Truck LS Conversion Kit to locate the block at the correct angle and secure the drivetrain without fabricating new mounts. It accepts T56, 4L60E and 4L80E transmissions without altering the floor and still clears deep sump or LH8 oil pans. Each American made piece ships with all necessary hardware so you can spend less time fitting parts and more time on the road.
Durable Welded Subassemblies for Rigid Support
The conversion kit uses TIG welding to join each motor mount and frame bracket into a single subassembly. This welding method delivers precise heat control and deep penetration, resulting in joints that withstand torque and road vibration without shifting. Machined surfaces ensure each component aligns exactly to factory specifications, so fit remains consistent across multiple installations. By combining robust steel with exacting fabrication, the kit maintains chassis rigidity while supporting the weight and power of an LS engine under load.
Integrated Polyurethane Transmission Support
Included polyurethane spacers and the transmission mount absorb shocks and maintain alignment during hard launches and cornering. Unlike traditional rubber mounts that can flex excessively over time, polyurethane offers controlled compliance and resists deformation under high torque. This design preserves the correct drivetrain angle, reducing wear on universal joints and drive shafts. The result is improved shift feel and a secure connection between the LS powerplant and your chosen gearbox.
Comprehensive Hardware Pack for Fast Installation
Every fastener and spacer needed for the swap ships with the kit, including grade 8 hardware for strength and corrosion resistance. By matching bolts and brackets at the factory, installers avoid last minute trips to the hardware store and potential mismatches. Each part is labeled and organized to follow a logical assembly sequence, cutting setup time and reducing the chance of errors. This all inclusive approach streamlines the installation and helps builders stay on schedule.
Broad LS Engine Compatibility and Sump Clearance
This kit accommodates nearly all Gen III and Gen IV LS engines, from small displacement to the largest 6.2 liter variants, with room for both Moroso high clearance and LH8 pans. Frame brackets are shaped to clear deep sump sections while keeping the oil pan secure, so you can choose a pan that suits racing or off road requirements. The brackets also preserve rail to pan distance for proper oil pickup. That adaptability makes the kit ideal for performance builds or daily drivers seeking reliability.
