Summit Racing™ Dual-Exhaust Transmission Crossmembers

Summit Racing™ steel transmission crossmembers allow you to run a true dual-exhaust system with most popular GM transmissions. They have a patented double-hump design, so you don't have to compromise ground clearance by running pipes under the crossmember, and they're a complete bolt-on deal—no custom fabricating or realignment is needed. The parts are made from 1/8 in. thick boxed tubing to handle the frame-twisting power of big blocks. Order the crossmember recommended for your vehicle and transmission application.

Hooker LS Engine Swap Transmission Crossmembers

Hooker LS engine swap transmission crossmembers are built to mount the transmission in place when switching to an LS engine. They are designed using CAD modeling/FEA analysis for optimal fitment, strength, weight, safety, and appearance. The crossmembers are manufactured from high-strength, low-alloy steel and then black powdercoated for maximum durability. They provide an engineered 3 to 3.5 degree engine/transmission inclination angle that is critical to obtaining suitable U-joint working angles. They are designed to be used in conjunction with Hooker LS engine swap brackets to provide a bolt-in installation of Hooker LS swap manifolds, headers, and exhaust systems for this application.

UMI Performance Boxed Weld-In Subframe Connectors

UMI Performance boxed weld-in subframe connectors are necessary chassis upgrades when racing and hard driving habits are present. UMI Performance boxed weld-in subframe connectors greatly improve your car's handling ability, while reducing T-top squeaks, dash rattles, and quarter-panel flexing. Subframe connectors essentially tie the front and rear steel subframes together, resulting in a stiffened and strengthened chassis, allowing for better weight transfer and improved traction when launching. When strength is a concern, square tubing has greater torsion resistance over tubular designs. They will work with all aftermarket exhaust systems and will not affect ground clearance. Their weld-in style requires no bolts to tighten and offer less chance of flex when compared with bolt-in types.
