LS Transmission Crossmember for Classic Chevy Frame Integration
When installing an LS crossmember on a 1973 to 1974 Chevrolet Nova frame, the 1973-1974 Nova Radiator (Manual Trans) with Fan steps in to ensure consistent engine temperatures and clear vital transmission mount points. Its dual core design employs high density fins and a tall corset that aligns precisely with stock mounting holes, eliminating any trimming of the core support. Each unit includes a molded shroud prewired for standard electric fans, delivering directed airflow over the radiator face and around manual transmission components. The sturdy brackets hold the assembly firmly in place while dual pass cooling passages maintain fluid circulation under both daily driving and light towing.
Streamlined No Welding Installation for LS Swaps
This crossmember requires no welding and drops directly into the stock frame rail holes, delivering a bolt in installation that saves hours of fabrication work. By aligning precisely with existing mounting points, it preserves the factory geometry and prevents the heat distortion that can follow cutting or welding. Installers simply secure the supplied brackets and hardware, maintaining chassis integrity and avoiding fitment guessing. The design also holds shifter clearance and transmission height exactly as intended, reducing the chance of misalignment. Builders benefit from a repeatable process that yields consistent driveline performance on every build.
Precision TIG Welding and Premium Steel Support
The crossmember is crafted from premium steel tubing with reinforced mounting plates to withstand the high torque output of modern LS powerplants. Each joint receives precision TIG welding to create clean, robust seams that resist fatigue and distortion under load. The selected steel grade offers an ideal balance of tensile strength and durability for street or track use. Reinforced areas absorb thrust from hard launches and towing, ensuring the assembly retains its shape and support over time. This robust structure safeguards against unwanted movement and vibration in demanding driving conditions.
CAD Based Direct Fit Ensuring Perfect Driveline Geometry
Developed with CAD contour matching, the crossmember hugs the frame profile of classic Chevy rails for an exact direct fit. This precise alignment maintains the correct angle between engine output and transmission input shafts, reducing driveline windup and vibration. The contour matched design also preserves clearance for brake and fuel lines, exhaust components and other underbody hardware. By eliminating the need for manual trimming or shimming, installers achieve ideal geometry with minimal effort. The result is a smooth power transfer and extended service life for universal joints and related components.
Versatile Transmission Mount for Multiple Gearboxes
This crossmember accommodates popular transmissions including TH350, 700R4, 4L60 and 4L80, giving builders flexibility in gear ratio selection and performance goals. The integrated mount features a rubber isolator that dampens harsh shocks and reduces noise under load, improving comfort and driveline longevity. Without altering the frame rails, owners can swap gearboxes quickly or upgrade to a different transmission footprint in the future. The durable mount resists fatigue and maintains consistent alignment, even under repeated torque cycles. Its adaptability makes this piece a long term solution for evolving LS swap projects.
