LS Engine Mounts and Frame Brackets for 1973-1987 4WD GM Trucks and 1973-1991 4WD SUVs
When installing an LS motor into a 1973-1987 GM 4WD truck or a 1973-1991 4WD SUV, these engine mounts and frame brackets solve the challenge of mismatched chassis rails by aligning the new powerplant to the original frame holes. Each bracket is precision laser-cut from heavy gauge steel and bent to OEM contour so you can bolt the LS engine directly without drilling or shims. They maintain correct engine angle under load and resist corrosion with a durable powder coat finish. By preserving factory geometry these parts shorten installation time and safeguard drivetrain alignment for smooth operation on road or trail.
Precision Laser Cut and Bent Brackets for Exact Engine Alignment
These mounts and brackets are crafted using precision laser cutting followed by controlled bending to replicate the exact frame rail hole pattern on 1973-1987 GM 4WD trucks and 1973-1991 4WD SUVs. By matching the original chassis contours, the LS engine is set at the factory recommended angle from the moment the first bolt is tightened. This method removes the need for trial fitting or on-the-fly modifications, delivering consistent alignment across multiple installations. Accurate placement reduces stress on transmission mounting points and minimizes vibration that can accelerate wear. The precise fit translates into uniform torque distribution through the driveline, extending the service life of connected components under both highway and off-road conditions.
Robust Steel Fabrication with Corrosion Resistant Finish
Manufactured from heavy gauge steel plate, each component provides exceptional yield strength and resists fatigue from repeated load cycles or road impacts. All surfaces, including weld seams and internal edges, receive a dense powder coat that forms a durable barrier against moisture, salt and debris. This finish not only prevents rust but also maintains mounting geometry by guarding against corrosion-induced distortions. Routine washing is sufficient to preserve the coating and structural integrity. Together, the robust material choice and protective finish ensure stable engine positioning and reliable chassis alignment in harsh environments.
Streamlined Pre Aligned Mounting for Faster Installation
Every bracket arrives pre aligned to OEM frame holes so the LS engine can be bolted directly into place without drilling or shims. The bent profiles match factory rails, eliminating complex measuring steps and reducing the risk of error that can lead to driveline binding or misfit. Included hardware allows installers to complete the setup in a single workflow, saving hours that would otherwise be spent sourcing or modifying fasteners. This approach simplifies LS swaps, transforming a multiday project into a more predictable, efficient process. Technicians benefit from a repeatable installation sequence that promotes consistent outcomes on each vehicle.
Built with precision and durable steel this kit ensures reliable LS engine alignment and lasting performance.
