LS Engine Mounts & Frame Brackets for 1973-1987 4WD GM Trucks and 1973-1991 4WD SUVs
Choosing the correct mounting solution is critical when transplanting an LS engine into a 1973-1987 GM 4WD truck or a 1973-1991 4WD SUV because the factory frame alignment differs from the original V8 layout. Each bracket assembly is precision laser cut and bent to match the exact frame rail hole patterns found on these GM trucks and SUVs so installers can bolt components directly to factory holes without drilling or shims. Fabricated from heavy gauge steel and coated with a corrosion resistant powder finish, the parts maintain engine angle under dynamic load and guard against rust from road debris or moisture. By preserving the original chassis geometry and drivetrain alignment, this solution cuts installation time, eliminates fitment guesswork and promotes reliable performance on paved highways or rugged backcountry trails.
Precision Alignment with Frame Rail Geometry
Utilizing laser cutting technology, these brackets reproduce the exact frame rail hole pattern found on 1973–1987 GM 4WD trucks and 1973–1991 4WD SUVs. This process ensures the LS engine is positioned at the factory recommended angle from the first bolt, preserving drivetrain geometry and reducing stress on the transmission mounting points. By eliminating drilling or shim adjustments, installers bypass trial fitting and avoid misalignment issues that can cause vibration or accelerated wear. The result is uniform torque distribution along the driveline, which extends the service life of connected components.
Heavy Gauge Steel Construction with Corrosion Resistant Finish
Formed from thick steel plate, each mount and bracket offers exceptional yield strength and resistance to fatigue under both highway loads and off road impacts. A dense powder coat is applied to every surface, including weld seams and edges, creating a protective barrier against moisture, salt and road debris. Routine cleaning is all that is needed to maintain this layer and prevent rust from compromising structural integrity. Together, the robust material and coating ensure that engine angle and chassis alignment remain stable in harsh environments.
Streamlined Installation Using Factory Mounting Points
Every component is bent to match chassis contours and pre aligned to the OEM frame holes so the LS engine bolts directly into place without extra measuring or adapters. Included hardware completes the assembly in a single workflow, saving time that would otherwise be spent sourcing fasteners. By mirroring the original mounting layout, this system minimizes installation steps and reduces the risk of error that can lead to driveline binding. Technicians gain a repeatable swap process that delivers reliable performance across multiple vehicles.
US Made Quality for Consistent Performance
Produced in the USA under stringent quality controls, these mounts and brackets adhere to factory specifications from steel forming through final inspection. Domestic production enables precise oversight of each fabrication stage, resulting in consistent dimensions and fitment for every kit. Installers can rely on uniform part geometry to achieve predictable alignment, eliminating surprises during engine swaps. This commitment to local craftsmanship ensures a durable and accurate mounting solution for demanding applications.
Engineered for precise fit and reliable performance in on road or off road applications.
