LS Transmission Crossmember for B-Body Nova Models
When fitting an LS transmission crossmember into a 1973-1974 Nova chassis with a manual gearbox, maintaining precise engine cooling is equally essential. The 1973-1974 Nova Radiator (Manual Trans) with Fan features a large volume aluminum core and an electric fan to hold temperatures in check under demanding conditions. It installs using factory mounting points for a direct bolt in fit that saves time and avoids modifications. By pairing precise transmission alignment with reliable coolant flow, this assembly delivers consistent performance on street or strip.
Precision Alignment for LS Engine Swaps
This crossmember is engineered to hold the transmission at the exact height and angle needed for B-Body chassis, eliminating alignment guesswork during an LS swap. By matching factory frame rail geometry, it minimizes vibration at the universal joints and reduces wear on couplings. Installers benefit from exact specifications that cut installation time and avoid repeated trial fits. The result is a drivetrain that runs smoothly across the rpm range, delivering consistent power without fatigue or noise under load.
Steel Plate Reinforcement Maintaining Chassis Rigidity
Fabricated from thick superior-grade steel plate, the crossmember doubles as a stiff bridge between the frame rails to resist torque spikes during hard launches and spirited cornering. This added rigidity preserves suspension geometry, so steering remains precise and tire wear stays even under stress. Whether on a tight back road or a drag strip, the strengthened structure prevents flex that can disrupt bracket alignment and chassis shape over time, ensuring reliable handling and long term durability.
Factory Mount Integration Streamlining Installation
All mounting holes align with existing factory attachment points on 1971-1976 B-Body models, allowing a true bolt in fit without welding or cutting. Common hand tools are all that's required and clear instructions guide installers step by step from prep through torque sequence. By preserving the original frame, installers avoid heat distortion, extra reinforcement or primer touch-up. This direct mount approach not only speeds assembly but also makes future removal or maintenance straightforward.
Optimized Drivetrain Integration for Enhanced Power Delivery
Specifically designed for LS setups, the crossmember positions the gearbox to reduce driveshaft angle and lower stress on universal joints. This precision chassis interface delivers more consistent torque transfer to the rear wheels, removing drivetrain lash and improving throttle response. Under acceleration, power pulses flow smoothly through the drive line, providing confident highway cruising and reliable performance when pushing on both street and strip. The overall effect is a refined driving experience with minimal compromise.
