Details

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.

Note: 1968-72 hardtops distance between crossmember frame holes is approximately 53-5/8". Measure your frame or crossmember to insure proper selection

  • Mounting hardware included
  • 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.

Application

Since different transmissions can share the same overall lengths as well as other measurements, they can also share some transmission crossmembers. G-Force has grouped the transmissions together that can share the same crossmember.

This Crossmember fits the GM-6 Transmission Group:

  • Hydra-Matic 8L90 transmission (8L90E) - Slip Yoke
