MuscleRods LS Foundation for 1973-91 GM C/K & Blazer Builds

High strength steel mount brackets ensure precise drivetrain alignment for your 1973-1987 GM Truck LS swap, eliminating vibration and avoiding transmission tunnel modifications. The complete MuscleRods Engine Swap Kit supplies all precision mounts and hardware for T56, 4L60E and 4L80E transmissions, supports a high clearance oil pan and preserves the classic C/K and Blazer aesthetic with dependable LS power built in USA.

MuscleRods LS Engine Swap Kit for 1973-1987 Chevy/GMC C/K Trucks and 1973-1991 K5 Blazer Jimmy

If you are tackling an LS engine swap into a classic GM C/K pickup or a K5 Blazer Jimmy the 2WD GM Truck LS Conversion Kit provides precision mounting and bracketry to match the LS crank centerline to the stock frame angle and preserve driveline geometry. Its CNC laser cut mounts and brackets secure T56, 4L60E and 4L80E transmissions without modifying the tunnel or relying on shims. By accommodating deep oil pans up to four inches thick the kit maintains proper pickup alignment and protects the sump on uneven terrain. Designers relied on existing frame holes and grade eight hardware to deliver a bolt in fit that safeguards chassis integrity and ensures stable performance under load.

Precision Engine Mounting for Accurate Driveline Alignment

The kit's CNC laser cut engine mounts position the LS crank centerline to match the original GM frame angle, preserving driveline geometry crucial for a smooth transfer of power. By aligning the engine without shimming or repeated test fits, installers eliminate misalignment that can lead to universal joint stress and premature bearing wear. Bolting directly into existing frame holes also reduces installation time and avoids welding, ensuring consistent torque distribution under load. This level of precision not only minimizes vibration but also enhances overall drivetrain durability for classic C/K trucks and Blazer Jimmy models.

Direct Fit Transmission Support for GM Truck Swaps

Engineered to accept T56, 4L60E and 4L80E transmissions without modifying the tunnel, the bolt in crossmember and outer bracket set connects the gearbox to factory frame openings. This design retains chassis strength by avoiding cuts or filler plates, while the included hardware pack features grade eight fasteners calibrated for proper clamp load. Cradling the transmission at its intended mount points ensures accurate driveshaft angles and reduces driveline wrap during acceleration. Technicians benefit from a streamlined process that requires no welding or complex fabrication, cutting install hours and preserving the truck's structure.

Enhanced Oil Pan Clearance for Reliable Lubrication

Mounting brackets are spaced to clear oil pans up to four inches in depth, supporting popular aftermarket and retro style pans without custom modification. By shifting the engine slightly forward and raising it within the frame, the kit maintains adequate ground clearance under the sump, protecting the pan on rough roads and steep driveways. Proper alignment of oil pickup tubes and internal baffling is preserved, preventing oil starvation under hard cornering or heavy acceleration. Builders can pair any compatible LS pan for these squarebody trucks and trust reliable lubrication under all driving conditions.

Durable Steel Brackets with Polyurethane Vibration Control

All mounting brackets and supports are fabricated in the United States from thick gauge steel to withstand the torque output of modern LS engines. Instead of conventional rubber, the kit uses polyurethane isolators that resist heat and solvent exposure while controlling engine movement with minimal deflection. Strategic gusset plates reinforce areas of highest stress, preventing deformation during repeated torque cycles. Each bracket set arrives with grade eight bolts and washers selected to match professional shop standards, ensuring that once installed, connections remain secure and vibration is kept to a minimum throughout the vehicle's life.
