G-Force 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. They're made from 2 in. x 3 in. boxed tubing (1/8 in. thick) to handle the frame-twisting power of any drivetrain you can throw at it!
FITS THE FOLLOWING TRANSMISSIONS: TH350, MUNCIE, POWERGLIDE, T-10, SUPER T-10, SAGINAW, TH200. FINISHED IN A BLACK POWDER COAT. INCLUDES NEW MOUNTING HARDWARE.
P/N RCG-350 INSTALLATION NOTES:
ON ALL 78-88 G BODY CROSSMEMBERS, THE PASSENGER SIDE HUMP IS THE TALLER OF THE TWO.
ON SOME INSTALLATIONS, IT IS NECESSARY TO REMOVE THE CATALYTIC CONVERTER HEAT SHIELD FROM THE PASSENGER SIDE FLOOR PAN.
THIS GENERATION OF VEHICLE IS PRONE TO BODY BUSHING COMPRESSION, EVEN WITH SOME SOUTHERN VEHICLES. IF THE FLOOR PAN IS TOO CLOSE TO ALLOW INSTALLATION, IT MAY BE NECESSARY TO REPLACE THE BODY BUSHINGS. SOME CUSTOMERS HAVE REPORTED THAT WITH SLIGHT INTERFERENCE INSTANCES, THEY HAVE BEEN ABLE TO GENTLY LIFT THE FLOOR PAN WITH THE ASSIST OF A FLOOR JACK AND A WOOD CUSHION, THUS PROVIDING THE REQUIRED CLEARANCE FOR INSTALLATION.
THE CROSSMEMBER IS INSTALLED SO THAT THE EXHAUST CLEARANCE HUMPS ARE CLOSED ON THE TOP AND OPEN ON THE BOTTOM.
