LS Engine Swap Transmission Crossmember for Manual Transmissions
If you're tackling an LS engine swap in a 1973-1974 Chevrolet Nova with a manual transmission, perfect driveline alignment starts with a dedicated crossmember engineered for that chassis. This transmission crossmember drops into existing frame rail holes for a bolt-in installation that requires no welding and aligns the input shaft for accurate driveline geometry. Built from premium steel tubing with reinforced mounting plates and precision TIG welding, it stands firm against the torque output of modern LS engines. By holding the engine and manual gearbox at the correct angle and preserving shifter clearance, it reduces vibration and premature component wear for dependable operation on both street and track.
Streamlined Bolt In Installation Saves Fabrication Time
The crossmember employs a drop in configuration that aligns precisely with existing frame rail mounting points, eliminating any cutting or welding of the chassis. Builders secure the unit using the supplied brackets and hardware, preserving the factory geometry and avoiding heat related distortions. This straightforward approach not only reduces installation time but also minimizes alignment errors that can lead to vibration or premature universal joint wear. By maintaining original mounting locations, each LS swap becomes a more predictable and repeatable process on 1988 through 1998 GM two wheel drive pickups.
Precision TIG Welded Premium Steel for Lasting Support
Crafted from premium steel tubing paired with reinforced mounting plates, this crossmember is engineered to withstand the high torque output of modern LS powerplants. Each joint receives precision TIG welding to produce clean, robust seams that resist distortion under load. The selected steel grade offers an ideal balance of tensile strength and fatigue resistance, ensuring that repeated launches or heavy towing duties do not compromise structural integrity. This robust foundation keeps engine and transmission assemblies firmly supported, translating power smoothly into the driveline.
CAD Based Direct Fit Ensuring Optimal Driveline Geometry
Developed through CAD contour matching, the crossmember conforms exactly to the frame profiles of 1988-1998 GM C1500, C2500 and C3500 two wheel drive chassis. This precise fit maintains the correct angle between engine output and transmission input shafts, reducing driveline windup and the risk of vibration. The design also preserves clearance for brake lines, fuel plumbing and exhaust components, preventing interference and simplifying installation. As a result, builders achieve ideal driveline alignment and extended service life of related components without custom trimming.
Adaptive Transmission Mounting for TH350 700R4 4L60 and 4L80
This crossmember accommodates a broad range of popular transmissions, including TH350, 700R4, 4L60 and 4L80 units, giving builders the flexibility to match gear ratios to performance, towing or efficiency objectives. The kit features a durable mount with a rubber isolator that dampens harsh shocks and reduces noise under load. By accepting multiple transmission footprints without altering the frame rails, this solution enables quick gearbox upgrades or swaps down the road. Its versatility makes it a go-to choice for diverse LS swap builds.
