Show original supplier description
The G Force RCB3-T56 is a robust transmission crossmember engineered for GM B-Body models including Caprice, Impala, LeSabre, Oldsmobile 88, Bonneville, Parisienne, and Catalina, specifically for the 1977-1990 model years. This crossmember is designed to work seamlessly with T-56, T-56 Magnum, T-56XL, Magnum XL, and TR6060 transmissions. A GF-GMATM Transmission Mount is included to ensure a proper fit for these transmissions. The unit is finished in a durable black powder coat and comes with all necessary mounting hardware for installation. Instructions are available for download. For optimal installation, it is noted that the provided 7/16″ hardware may require enlarging frame rail holes to 1/2″. Alternatively, using stock 3/8″ hardware is possible, but Grade #8 fasteners are strongly recommended for compensation. Key specifications include a weight of 37 lbs and shipping dimensions of 51 x 19 x 6 inches. The crossmember should be installed with the G Force label facing the rear of the vehicle. A distinguishing feature is the center tube with a 1/2″ drain slot positioned on the bottom and passenger side. The exhaust clearance humps are to be closed on the top and open on the bottom after installation.
