• Mounting hardware included
• This crossmember is installed with the GForce label facing the REAR of the vehicle.
• 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.

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.
