LS Mounts & Brackets for Faster Swaps on 73-87 GM 4WD Truck/SUV

Optimized for LS swaps on 1973-1987 GM 4WD trucks and 1973-1991 SUVs, these engine mounts and frame brackets deliver precise factory point alignment and slash installation time by requiring minimal modifications. Laser cut from heavy gauge steel with a corrosion resistant powder coated finish, each bracket ensures rugged reliability, resists wear, and supports lasting performance backed by US made craftsmanship.

LS Engine Mounts and Frame Brackets for 1973-1987 4WD GM Trucks and 1973-1991 4WD SUVs

Installing an LS engine into a 1973-1987 4WD GM truck or a 1973-1991 4WD SUV often stalls when mounts don't align perfectly with the original frame. These precision bent brackets and laser cut engine mounts bolt directly to factory holes without extra drilling or shimming and position the powerplant at the correct angle. Fabricated from heavy steel and finished with a powder coat resistant to moisture and road debris the assemblies prevent rust and preserve alignment under load. By matching original mounting points they cut installation time and eliminate ongoing fitment headaches for reliable performance on and off road.

Precision Laser Cut and Bent Brackets for Exact LS Positioning

The mounts and brackets are manufactured by a laser cutting process that replicates factory hole patterns on GM chassis with exacting accuracy. This technique eliminates the need for trial fitting, shims or drilling, ensuring the LS engine is held at the correct angle from the outset. Precision bending conforms to the contours of the frame rail, maintaining the proper drivetrain geometry under load. This approach reduces stress on transmission mounts and shaft joints by preserving original design tolerance. Installers benefit from a one step bolt up, with confidence that alignment aligns with the factory setup. The result is consistent engine placement for improved performance and reduced wear.

Robust Powder Coated Steel Construction Against Corrosion

Each bracket and mount is formed from heavy gauge steel that delivers high yield strength and fatigue resistance in demanding applications. A uniform powder coat finish provides a dense barrier against moisture, road salt and debris, preventing corrosion that can compromise structural integrity. This coating adheres tightly to weld seams and edges to block rust wherever surfaces meet. Routine washing is all that is needed to preserve the protective layer, keeping appearance and performance intact over years of use. By shielding key contact points, the finish upholds consistent alignment and reduces the risk of unexpected failure. Users gain peace of mind knowing critical support components remain unaffected by harsh environments.

Pre Aligned Fitment Streamlines Installation for GM Chassis

Designed specifically for 1973 through 1987 4WD GM trucks and 1973 through 1991 4WD SUVs, these mounts bolt directly to factory holes without modification or shimming. Pre aligned mounting points mirror the original layout, cutting installation time and minimizing the steps required to secure the engine and transmission. Hardware is included for a complete assembly, letting technicians move from fitment to torque in one workflow. This kit based solution eliminates guesswork and reduces the margin for error, which can lead to costly adjustments down the road. Consistent fitment across every set also means repeatable results for fleet or multi vehicle projects. The streamlined process enhances productivity and confidence during complex powertrain upgrades.

Engineered for a precise fit and lasting reliability in your LS swap project.
