Precise LT Mounts & Brackets for 1973-1987 4WD Trucks

Proven high strength steel brackets ensure precise LT engine alignment in 1973 to 1987 GM 4WD trucks, eliminating guesswork and accelerating your swap. Built for rugged terrain and highway cruising, the kit's pre aligned mounts and included fasteners deliver a straightforward, hassle free install and lasting driveline stability.

LT Engine Mounts and Frame Bracket Kit for 1973-1987 GM Truck 4WD

Swapping an LT V8 into a classic GM 4WD truck often turns into a puzzle of clearances and mounts. This kit matches factory mounting points on 1973 to 1987 GM frames for a direct fit that cuts installation time. Engine support stays rock solid over rough terrain and open highway duties thanks to heavy gauge steel brackets and mounts. By using pre-drilled holes and factory matched attachments, the assembly guarantees precise alignment through every mile.

Precision Alignment with Factory Mounting Points

This kit's brackets and mounts are engineered to match the original mounting points on 1973–1987 GM truck frames and compatible SUVs through 1991, delivering a precise LT engine placement without fabrication. By using factory matched attachment locations and predrilled holes, each powerplant seats squarely in the chassis rail path, eliminating guesswork and on-the-fly adjustments. Accurate alignment preserves correct drivetrain angles, which in turn reduces stress on the transmission and differential over time. The result is a swap process that is both faster and more reliable, with no need for custom fitment or trial fitting at installation.

Heavy Gauge Steel Construction for Lasting Strength

Manufactured from robust steel plate, the frame brackets and engine supports are built to endure both rugged backroad excursions and sustained highway cruising. The material's high yield strength resists bending under load and provides a rock-solid foundation for the LT powerplant. Critical weld joints receive extra reinforcement at peak stress areas, ensuring that vibration and torque forces do not compromise the assembly. This durable construction minimizes maintenance needs by reducing the risk of fatigue or deformation through years of service.

Simplified Installation to Expedite Your Swap

Every component in this all-in-one kit is designed for plug-and-play installation, requiring only basic hand tools and no frame modifications. Predrilled holes align with existing bolt patterns, guiding installers through a clear, step-by-step sequence that cuts labor hours significantly. By removing the need for shims or custom adapters, the process avoids common pitfalls that can delay engine swaps. This streamlined approach not only saves time but also helps keep project budgets on track by eliminating unexpected fabrication costs.

Unified Mounting System for Enhanced Stability

Combining engine mounts with frame brackets in a single integrated assembly delivers lateral and longitudinal support to the LT motor under all driving conditions. This synergy reduces engine movement during hard acceleration, braking, and cornering, translating into smoother operation and less vibration through the cab. Consistent support also helps maintain optimal driveshaft angles, protecting universal joints and transmission output. Whether you're navigating winding country roads or hauling loads on the highway, the unified system ensures refined performance and long-term reliability.

Engineered for a precise fit and lasting performance in your LT swap.
