1977-1990 Caprice/Impala LT Swap Power by MuscleRods

Precision-crafted steel brackets ensure effortless LT engine installation in 1977 to 1990 B-Body Caprice and Impala models by maintaining correct drivetrain alignment, minimizing vibration and preserving original stance and appearance without modifying the transmission tunnel. MuscleRods LT Series AC/Power Steering Bracket 6.6L L8T kit provides custom mounts and hardware for multiple transmissions, saves installation time, and delivers reliable smooth performance backed by genuine American craftsmanship.

MuscleRods LT Engine Swap Kit B-Body AC and Power Steering for 1977-1990 Chevy Caprice/Impala

When adding air conditioning and power steering to an LT swap in a 1977-1990 Chevy Caprice or Impala, the LT Series AC/Power Steering Bracket 6.6L L8T provides a precise mount that aligns components to factory dimensions. Crafted from laser-cut steel, this bracket secures the compressor and steering pump directly to the 6.6L L8T block without fabrication or guesswork. With bracket points engineered to match original block bosses and frame clearance, installers maintain ground clearance and chassis alignment. Offered by MuscleRods, the solution delivers straightforward integration within the complete Engine Swap Kit platform.

Preserving Drivetrain Geometry to Minimize Vibration

Maintaining the correct drivetrain angle is crucial for preventing stress on universal joints and reducing unwanted vibration. The bracket geometry aligns the LT engine and transmission to factory spec, improving noise vibration and harshness characteristics that can plague a swap without precise mounting points. Integrated polyurethane bushings cushion road shock while holding the driveline in position under load, so passengers enjoy a smoother ride. By preserving the intended output shaft angle, this design helps extend the life of the transmission and driveshaft components. Enthusiasts benefit from a refined power transfer that feels more like an original factory installation.

Seamless Mount Integration Without Tunnel Alterations

This bracket kit bolts directly to existing frame bosses and transmission crossmember locations without cutting or reshaping the tunnel. Custom-fit frame brackets match the exact chassis contours of 1977 to 1990 Caprice and Impala models, eliminating the need for welds or spacers. Installers can retain the original floorpan heat shielding and preserve ground clearance by avoiding complex modifications. Support points for 4L60E and 4L80E transmissions are incorporated in the design, ensuring a bolt-in fit that stays true to the factory footprint. This approach removes guesswork and conserves both time and vehicle structure integrity.

High Strength Steel Construction and Secure Fastening

All mounting components are formed from high strength steel and produced in the United States for consistent material quality and dimensional accuracy. The precision laser cut plates and CNC formed brackets provide uniform hole patterns that align effortlessly on the engine block and frame rails. Grade 8 hardware is included to deliver superior clamping force, resisting fatigue through repeated load cycles and corrosion over time. Welded seams are executed with professional procedures to ensure bracket rigidity without distortion. This robust fabrication process underpins reliable long lasting performance under spirited driving conditions or regular highway use.

Comprehensive Component Kit for Streamlined Installation

Designed as a complete solution, this kit combines engine mounts, frame mounts, transmission crossmember, transmission mount and supporting frame brackets into one package. Each part is engineered to work in unison, so installers can position the LT powerplant and gearbox quickly without fabricating custom adapters. The inclusive design covers critical interfaces from block bosses to chassis rails, allowing a consistent installation flow from start to finish. By pooling these key components into a single kit, the process avoids part sourcing delays and fitment errors. The result is a straightforward swap that preserves factory aesthetics and stance while unlocking modern LT performance.

This MuscleRods kit is designed for a straightforward installation. For a more robust kit where you can build this same kit but this is a customizable kit where the user can select their own parts to better suit their needs see our Complete LT Swap Kits - LT Kit Builder.
