Complete MuscleRods LT Engine Swap Kit for 1958-1964 Impala
If you're retrofitting a Gen V LT engine into your 1958-1964 Impala B-Body, the Complete LT Engine Swap Kit from MuscleRods provides all the custom brackets, mounts and hardware to clear the factory rails and position the powerplant precisely for a straightforward installation. Engine placement hinges on custom machined supports that maintain correct driveline angles, absorb vibration and protect transmission seals by eliminating undue stress on the stock frame. By tying both rails together with a reinforced crossmember designed to withstand higher torque loads, the kit helps keep chassis rigidity and alignment stable while a bolt-in transmission mount fits both 4L60E and 4L80E transmissions without any tunnel or frame alterations. All brackets, mounts and the crossmember are made in the USA from heavy gauge steel with corrosion resistant finishes, preserving the Impala's classic lines and providing reliable performance on the street or strip.
Precision Engine Positioning for Consistent Torque Delivery
Engine mounts and bracket assemblies are machined to precise tolerances to position the LT powerplant within the Impala B Body frame. This exact placement preserves ideal drivetrain angles and limits vibration transfer to the chassis. By aligning the crankshaft with the transmission centerline, the system reduces wear on seals and bearings for smoother power delivery. Technicians find that consistent engine orientation also shortens calibration time when adjusting engine management and driveline components. The outcome is a refined throttle response and reduced noise, vibration and harshness for an authentic driving experience.
Reinforced Crossmember Boosting Frame Support
The reinforced crossmember spans both factory rails with a robust support structure crafted from American steel. Engineered to handle the torque output of Gen V LT engines, it resists bending under load and maintains chassis alignment during hard acceleration and cornering. By distributing stress evenly across the rails, it prevents localized fatigue and safeguards the factory frame from distortion. This bolt-in design installs without cutting or welding, preserving original architecture while delivering the rigidity needed for spirited driving.
Streamlined Installation with Preconfigured Transmission Mount
The transmission mount arrives preassembled for 4L60E and 4L80E units, requiring no alteration to the floorpan or frame tunnels. Preinstalled inserts and hardware align precisely with stock mounting locations, eliminating fabrication guesswork and reducing installation time. Installers simply position the mount, secure the hardware and tie in driveline components with assurance in their alignment. This straightforward approach maintains the Impala's factory appearance and avoids common clearance headaches under the interior.
American Made Steel Components for Enduring Reliability
All brackets, mounts and the crossmember are manufactured in the United States from heavy gauge steel and finished with a corrosion resistant coating. Domestic production includes quality inspections at each stage to guarantee consistent fitment from chassis to chassis. This rigorous process ensures durability under daily driving or track use, where repeated heat cycles and road exposure can challenge lesser materials. Owners can trust in a swap solution that combines proven performance with the long-term reliability expected in a classic restoration.
