LS Engine Mounts and Frame Brackets for 1973-1987 4WD GM Trucks and 1973-1991 4WD SUVs
Fitting an LS powertrain into a 1973-1987 4WD GM truck or a 1973-1991 4WD SUV demands precise mounting to avoid clearance headaches and misalignment. These laser-cut engine mounts and frame brackets bolt directly to original frame holes and lock the powerplant into the correct position. Powder coated steel construction guards against corrosion on the factory chassis rails. Matching factory bolt patterns set the proper engine tilt under load and cut down on trial fitting time.
Precision Laser Cut Mounts for Exact LS Positioning
The frame brackets are produced using laser cutting to match original frame hole patterns on 1973 through 1987 four wheel drive GM trucks and 1973 through 1991 four wheel drive SUVs. This manufacturing method delivers hole locations that require no extra alignment work or shim fitting, ensuring that the LS engine installs with the correct tilt and clearance the first time. With mounting points that line up precisely to factory specifications, installers can secure the engine confidently and reduce the time spent on test fits. Proper geometry is maintained under load so that engine movement is minimized during acceleration and towing.
Powder Coated Steel for Superior Corrosion Resistance
Each mount and bracket is fabricated from heavy gauge steel and finished with a uniform powder coat process that resists moisture, road grime and stone impact. This protective layer prevents rust formation even in damp or salted road conditions, preserving structural strength and appearance over the long term. By guarding critical connection points from corrosion, the coating ensures that engine alignment remains consistent season after season. Maintenance is simplified since the protective finish requires little more than routine cleaning to stay effective.
Maintaining Drivetrain Alignment with Custom Bent Brackets
The brackets are precision bent to follow the factory frame rail contours of specific GM chassis, delivering direct bolt up installation without chassis modification. This tailored bending approach ensures that the powerplant and transmission stay in perfect line with driveline components, reducing stress on the transmission mount and drive shaft. The rigid assembly resists flex under engine torque and vibration, which helps to minimize wear on seals and joints. Such accurate fitment contributes to smoother power delivery and a more reliable driving experience.
Made in the United States with Rigorous Quality Controls
Manufactured domestically, each bracket assembly undergoes strict inspection protocols to verify weld integrity and dimensional accuracy. Quality control measures include material certification and visual defect assessments to ensure consistency across every set. The result is a repeatable fit that installers can rely on to meet factory tolerances without additional fabrication. This commitment to US production standards delivers dependable performance for off road use and daily driving alike.
Engineered for a precise fit and long-term durability in your LS swap, these mounts and brackets ensure reliable alignment season after season.
