LS Engine Mounts and Frame Brackets for 1973-1987 4WD GM Trucks and 1973-1991 4WD SUVs
When installing an LS motor into a classic GM 4WD truck or SUV from the seventies and eighties precise fitment is vital. The Engine Mounts & Frame Brackets kit provides a direct bolt on solution with precision laser cut and bent steel brackets that match factory frame holes without shims or drilling. Crafted in the USA from high grade steel with a corrosion resistant powder coat finish the kit includes two engine mounts two frame brackets and all hardware. Featuring pre aligned mounting points this assembly holds the LS powertrain at the correct angle under load to reduce vibration and driveline stress while cutting installation time.
Custom Fitment for GM 4WD Classics
These engine mounts and frame brackets are engineered to fit 1973 to 1987 four wheel drive GM pickup trucks and 1973 to 1991 four wheel drive GM sport utility vehicles. Each bracket and mount features pre aligned mounting points that match factory frame holes, minimizing the need for drilling or trimming. By securing the LS engine at the correct angle, the design ensures proper transmission shaft alignment, reduced driveline vibration and consistent power transfer. For installers using MuscleRods crossmember kits, the bolt patterns match precisely, so the entire powertrain sits square within the chassis and preserves factory drive line geometry.
Rugged Steel Construction with Protective Finish
Each mount and bracket is formed from high grade steel, then precision bent, laser cut and powder coated to resist corrosion and abrasion. This choice of material and process delivers exceptional strength to handle high torque loads under off road and daily driving conditions. The protective finish stands up to salt, mud and water exposure, helping maintain original appearance and structural integrity over years of use. Components are manufactured in the USA by Muscle Rods, reflecting strict quality control standards for consistent performance.
Optimized for LS Engine Swaps
Designed specifically for GM LS engines, these mounts provide the correct geometry for engine placement without the need for custom adapters. The mounting pads align with LS block bosses to deliver a rigid connection, while spacing has been calculated to clear cross members and exhaust manifolds. By retaining factory sensor locations and accessory drive clearance, the design simplifies wiring harness routing and accessory installation, allowing a cleaner build and enhanced service access. Proper placement also contributes to balanced weight distribution, improving handling and reducing strain on suspension components.
Streamlined Installation Process
The kit includes all required brackets, mounts and hardware, allowing a true bolt on experience. No modifications to the frame rails are needed, and the instructions guide you through each step with clear illustrations. Straightforward bolt torque values ensure repeatable installation and safe operation. Integration with MuscleRods mounting products guarantees that engine and transmission angles remain within factory specifications, reducing noise and wear over time. This complete solution brings professional grade engineering to your project and cuts installation time significantly.
Trust MuscleRods for a solid foundation when swapping an LS engine into your classic GM 4WD truck or SUV.
