SHOPTALK
See the G Force Crossmember Overview for more info.
Many G Force Crossmembers utilize the early GM double stud transmission mount configuration, for the increased strength aspects. Should your vehicle originally be equipped with a single centered stud transmission mount, simply replace your transmission mount with the early style.
For vehicles originally equipped with 3/8″ crossmember bolts, open existing holes on frame to 1/2″. If you prefer to retain 3/8″fasteners, upgrade the installations hardware to Grade 8 bolts and hardened flat washers.
