LS Transmission Crossmember for 1973-1974 Chevrolet Nova Manual Transmission Models
When swapping an LS motor into a 1973-1974 Chevrolet Nova with a manual gearbox, proper engine cooling is often overlooked yet critical to reliable operation. This radiator with fan integrates a robust aluminum core precisely contoured to the Nova's chassis and ensures clearance around shifter linkages. Designed to sustain elevated coolant flow and maintain target operating temperatures under varied driving conditions, it keeps the powerplant running smoothly on both street cruises and open throttle runs. Mounting follows factory locations, requiring no drilling or welding and delivering immediate fan control right out of the box thanks to its plug-in connector and included shroud.
Streamlined no weld installation accelerates swap completion
The crossmember leverages a drop in design that aligns with existing frame rail holes, eliminating the need for cutting or welding. By using supplied bolts and brackets, builders can install the unit in a fraction of the time it takes to fabricate or modify a tube style support. This approach not only preserves the chassis integrity by avoiding heat distortion, it also reduces the risk of alignment errors that can arise when custom trimming or fitting is required. Whether it's your first LS swap or you're building multiple trucks, this straightforward installation method helps you stay on schedule and prevents common pitfalls during assembly.
Robust steel construction ensures enduring chassis support
Crafted from premium steel tubing and reinforced mounting plates, this crossmember stands up to the extreme torque output of modern LS engines without bending or cracking. Each joint is secured with precision TIG welding, which produces clean, strong seams and minimizes distortion so the parts retain exact geometry under load. The steel used has been selected for its balance of tensile strength and resistance to fatigue, so repeated stresses from launches, towing or off-road use won’t compromise structural integrity. This solid foundation gives you confidence that engine and transmission remain rigidly supported throughout hard driving and long term use.
Precision fit for accurate driveline alignment on GM C1500 C2500 C3500
Developed using CAD based contour matching, the crossmember conforms precisely to the frame profiles of 1988 through 1998 two wheel drive GM pickups, guaranteeing a direct fit with no trimming required. This exact positioning keeps the LS engine and chosen transmission within the optimal angle range, reducing the likelihood of driveshaft windup, vibrations, or premature u-joint wear. In addition, the design maintains factory clearances for brake lines, fuel lines and exhaust headers, eliminating interference issues. The result is a clean underbody layout that delivers smoother operation and extends the service life of related driveline components.
Flexible compatibility across TH350 700R4 4L60 4L80 gearboxes
The crossmember is tuned to accept a range of popular automatic and manual transmission models, including TH350, 700R4, 4L60 and 4L80 units, making it ideal for diverse build goals. By accommodating multiple transmission footprints, it simplifies part sourcing and enables future gearbox swaps without additional modifications to the frame rails. The inclusion of a durable transmission mount with vibration isolating bushings further ensures that power delivery remains smooth while damping harsh driveline shock. This adaptability allows builders to select the transmission best suited for towing, street performance or track duty without compromising fitment or requiring separate mounting solutions.
This crossmember provides a bolt-in installation and robust support to maintain optimal alignment for your LS drivetrain.
