TRA-810 installation notes:

This crossmember is installed with the G Force label facing the rear of the vehicle. A second determining feature is crossmember center tube has a 1/2″ drain slot located on the bottom and on the passenger side next to the hump weldment.

The crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom.

To utilize the provided 7/16 hardware it is necessary to enlarge the holes in the frame rails. If the installer chooses to utilize the stock size 3/8 hardware, it is strongly recommended that the installer obtains Grade 8 fasteners and washers to compensate.

Finished in a durable black-satin powdercoat paint. Includes new high-strength, Grade #8 mounting hardware. Purchase transmission mount separately. A Polyurethane transmission mount recommended.

( Note: The distance between crossmember frame holes is approximately 30-1/2″. Measure your frame or crossmember to insure proper selection.)
