MuscleRods Core Mounts for 1977-1990 B-Body LT Swaps

Optimized for 1977 to 1990 Caprice and Impala applications, the LT Series AC/Power Steering Bracket 6.6L L8T kit delivers flawless drivetrain alignment while eliminating tunnel modifications for a streamlined LT engine swap. MuscleRods custom steel mounts and comprehensive hardware integrate with multiple transmissions to preserve original stance, minimize vibration, and provide reliable, smooth performance backed by genuine US craftsmanship.

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

When planning an LT engine conversion in a 1977 through 1990 Chevy Caprice or Impala, ensuring precise alignment of the AC compressor and power steering pump on the 6.6L L8T block can be a time consuming challenge unless you choose the LT Series AC/Power Steering Bracket 6.6L L8T. By matching original block bosses and frame rail bosses, this bracket secures both components without tunnel alterations and retains factory ground clearance. Offered by MuscleRods, the complete bracket set uses laser cut steel plates and Grade 8 hardware for reliable fitment across 4L60E and 4L80E transmissions. Installers benefit from consistent drivetrain geometry that reduces vibration and preserves the original stance of the classic B-Body.

Precision Alignment for Reduced Drivetrain Vibration

Maintaining the correct angle between the LT engine and transmission is vital to prevent stress on universal joints and minimize noise vibration and harshness. This bracket set positions the AC compressor and power steering pump on the 6.6L block bosses to match factory mounting points precisely. By holding the driveline alignment under load and integrating polyurethane bushings, it absorbs road shock while preserving a straight driveline path. The result is smoother power delivery and extended service life for drivetrain components.

Chassis Integration That Preserves Ground Clearance

The custom fit design bolts directly to existing frame bosses and crossmember locations without modifying the transmission tunnel or reshaping the floorpan. Installers retain original heat shielding and the factory ride height by following the bracket's geometry, which matches the contours of 1977 to 1990 Caprice and Impala rails. This precise mapping eliminates the need for cutting or welding and ensures the underbody clearance remains unchanged. Preserving the stance and protecting vehicle structure helps maintain factory aesthetics.

Laser Cut Steel Construction and Heavy Duty Fasteners

All components are crafted from laser cut steel plates formed to exact tolerances for dependable block to frame alignment. Welded seams follow strict professional standards to prevent distortion and maintain rigidity under load. The kit includes grade 8 bolts that deliver superior clamping force, resist fatigue, and stand up to corrosion over time. With material and hardware sourced from US suppliers, quality and consistency are assured, supporting reliable performance in daily driving or spirited use.

Complete Bracket Kit Simplifying Installation

This all inclusive package brings together engine mounts, frame mounts, transmission crossmember, transmission mount, and supporting frame brackets in one cohesive kit. Each element is designed to work in concert, reducing part sourcing and fitment errors during an LT swap. Clear mounting locations and included hardware allow installers to follow a seamless workflow from block boss attachment to rail integration. By unifying these key components, the swap process becomes faster and more predictable, saving time in the garage.
