    G Force Crossmembers RCAEC2-4L80 Details

    G Force Performance is the premiere source for transmission crossmembers. Whether you're looking for an upgrade from stock components or parts crossmember to accommodate your all of your transmission needs and provides clearance for large diameter aftermarket dual exhaust systems. Finished in a black powder coat and includes new mounting hardware.

    The supplied aluminum spacers are utilized to provide custom positioning of the transmission mount. They are to be positioned between the crossmember and the transmission mount. Select the desired amount of spacers and match a bolt of proper length to insure full engagement into the transmission mount. Some applications will not require any spacers. Some vehicles of this generation are equipped with a crossmember that bolts directly to the vehicles frame rail, while others are equipped with a crossmember that utilizes a tab that sets on the frame rail and is then clamped by a steel cap that is embedded with a rubber liner. The RCAE crossmember bolts directly to the frame rail and utilizes the factory frame holes. To utilize the provided 7/16 hardware it is necessary to enlarge the holes in the frame rails with a 1/2" drill. If the installer chooses to utilize the stock size 3/8 hardware, it is strongly recommended that the installer obtain Grade 8 fasteners and washers to compensate.

    Note: The distance between crossmember frame holes is approximately 53-5/8". Measure your frame or crossmember to insure proper selection
