Precision Machined LS Engine Swap Motor Mounts for Exact Fitment
As you retrofit a 6.6L L8T into a classic 1949 to 1954 Chevy chassis, alignment between the LS block and stock frame rails can create persistent challenges. The LT Series AC/Power Steering Bracket 6.6L L8T addresses that gap with precision heat treated steel plates machined to mirror original bolt patterns. Its tight tolerances preserve the correct crank centerline to driveshaft angle and maintain factory engine tilt without shims or frame modifications. Installation uses pre drilled holes and included grade eight hardware so you can secure the assembly quickly while minimizing vibration transfer and belt wear.
CNC Machined Plates for Exact Block-to-Frame Alignment
The LT Series bracket plates are machined to mirror the original bolt patterns of 1949 through 1954 Chevy frames, ensuring the LS block sits precisely at the factory crank centerline. By recreating the stock rail profile, these components eliminate angular offsets that often lead to driveline stress and premature universal joint wear. This level of precision means installers can forgo shims or chassis modifications, reducing setup complexity while preserving the truck's handling balance. Over time, correct alignment also prevents uneven load on the driveshaft, maintaining smooth power delivery.
Heat Treated Steel Construction for Lasting Strength
Each bracket is formed from premium steel and subjected to a controlled heat treat cycle that maximizes toughness and yield strength. This process fortifies the plates against cyclic torque loads and frame flex common in spirited acceleration or heavy towing. Strategic welding at high-stress junctions further reinforces structural integrity, preventing crack initiation under dynamic forces. In daily driving or weekend cruising, users will notice consistent clamping pressure and negligible deformation even after extensive road time.
Comprehensive Hardware Kit Streamlines Assembly
Rather than sourcing fasteners, the kit provides a full complement of bolts, washers and lock nuts all rated to grade eight specifications. Pre drilled holes in the brackets line up directly with factory mounting points, allowing technicians to secure the assembly with standard hand tools and a torque wrench. Detailed instructions guide the installer through correct bolt orientation and specified torque values, reducing the risk of misalignment or loose connections. As a result, total installation times shrink and even first-time LS swappers achieve a factory-like fit.
Vibration Control Enhances Throttle Response
By firmly anchoring the LS engine to the chassis with optimized contact surfaces, these mounts minimize unwanted movement under load changes. Keeping the crank centerline true reduces harmonic oscillation in accessory belts and pulleys, extending their service life. The rigid connection also dampens engine shake at idle and during gear shifts, translating to a more direct feel at the pedal. Drivers benefit from a quieter ride with sharper throttle feedback on both street runs and highway stretches.
