MuscleRods LS Engine Swap Kit for 1988-1998 C1500 and 1992-1999 Tahoe/Yukon
If you're swapping in an LS engine under the hood of a 1988-1998 two wheel drive GM pickup or SUV, the MuscleRods 1988-1998 2WD GM Truck LS Conversion Kit addresses fitment challenges from engine mounts to transmission crossmember alignment. Each component has been shaped to hold the LS block at the correct angle and work with popular transmissions such as the T56, 4L60E and 4L80E without any need to alter the floor. The frame mounts lock the powertrain in place while leaving room for Moroso and LH8 oil pans, and every piece comes ready to install with all the hardware you need. By focusing on mechanical precision, the kit cuts down on vibration and lets you get back on the road with reliable GM muscle and modern engine tech.
Precision Engine Mounting for Reduced Vibration
This conversion kit features motor mounts and frame brackets engineered to hold the LS block at the optimal angle relative to the truck frame. By maintaining a precise drivetrain angle, the system minimizes torsional forces that cause noise and harshness at highway speed. The robust construction of the mounts ensures that power is delivered smoothly to the drive shaft, resulting in a refined feel even under heavy throttle. Careful attention to alignment also protects other drivetrain components from premature wear and delivers consistent performance mile after mile.
Direct Fit Design for Popular GM Transmissions
The package includes a transmission crossmember and mount that accept T56, 4L60E, 4L80E and 6L80E boxes without modifying the tunnel when using the two four speed units. Eliminating the need for floor alterations simplifies the process and reduces shop time. A polyurethane transmission mount and tailored spacers ensure firm support under cornering and hard launches. This direct fit approach streamlines any LS swap and provides confidence that the engine and gearbox will align perfectly from the start, letting you spend less time on fabrication and more time on the road.
Oil Pan Accommodation for High Clearance Applications
Recognizing that many enthusiasts choose deep sump pans for track use or off road clearance, the frame brackets are shaped to create extra room under the block for both Moroso High Clearance and LH8 pans. This added space prevents interference with the crossmember and lets you select a pan based on your performance or ground clearance needs. By integrating precise weld locations and clearance cutouts, these brackets guard against pan damage while preserving chassis rigidity. The result is a clean installation that does not force you to compromise on component choice.
Complete American Made Kit for Easy Installation
Every piece in this conversion set is manufactured in the USA, adhering to strict quality standards. The kit arrives with two motor mounts, two frame brackets, a transmission crossmember, outer crossmember brackets, a polyurethane transmission mount with spacers, and all necessary hardware. This comprehensive package means there is no need to hunt for extra parts once you begin your swap. Welded subassemblies and finish machining deliver consistent fitment part after part, making the upgrade process straightforward for seasoned builders and first time installers alike.
