MuscleRods LT Engine Swap Kit for 1958-1964 Impala B-Body
If you're swapping an LT engine into your 1958-1964 Impala the 1958-1964 B Body LT Conversion Kit delivers mounts and brackets that solve fitment challenges without altering the frame. The kit from MuscleRods includes a reinforced crossmember and transmission mount engineered for precise engine alignment and consistent operation. Hardware is arranged for quick assembly and supports both 4L60E and 4L80E transmissions with no modifications needed. Components made in the USA are built to handle increased torque and offer reliable modern performance while preserving your Impala's original character.
Precision Engine Alignment with Custom Mounts
The LT Conversion Kit's precision engineered engine mounts and brackets ensure the powerplant sits perfectly within the 1958-1964 Impala B-Body chassis. By maintaining exact driveline angles, these custom mounts reduce vibration and stress on both the engine and transmission. This careful alignment translates into smoother power delivery and decreased wear on peripheral components. Technicians benefit from predictable fitment, which cuts installation time and minimizes adjustment once the engine is in place.
Reinforced Crossmember for Structural Stability
At the heart of the kit lies a reinforced crossmember designed to tie the frame rails together, providing a solid foundation for higher torque outputs of Gen V LT engines. This robust structure resists flex under acceleration and cornering forces, preserving chassis geometry even under heavy load. By bolstering the factory frame's load-bearing capacity, the crossmember enhances handling precision and reduces the risk of metal fatigue over time. Owners will notice a firmer feel on the road and greater confidence when pushing the engine's performance limits.
Integrated Kit Design for Effortless Installation
Every bracket, mount, and piece of hardware in this all-inclusive kit is engineered to work in harmony, eliminating the need for chassis modifications or custom fabrication. The transmission mount is preconfigured for both 4L60E and 4L80E applications, requiring no tunnel alterations for a direct fit. Clear fitment points and included fasteners guide installers through each step, making the swap process accessible to both seasoned professionals and dedicated DIY enthusiasts. The result is a streamlined installation that preserves the Impala's original architecture.
American Craftsmanship that Handles Modern Torque
All components are proudly manufactured in the USA from premium metals chosen for strength and corrosion resistance, ensuring the rigors of modern engine performance are met without compromise. Rigorous quality control and familiar manufacturing processes deliver consistent part precision and surface finishes that stand up to everyday use. The robust build quality underpins reliable operation and long service life, whether the vehicle sees daily driving duty or regular track sessions. This attention to detail safeguards your investment and keeps your classic Impala running with confidence.
