The TCI crossmember line will be available for a range of classic vehicles, including the GM A-body series offered from 1967 to 1974, the GM F-body series from 1967 to 1981, the GM X-body series from 1968 to 1974, C-10 pickups from 1967 to 1981, and more. A universal adjustable model fits tube frames, street rods and customs with 32- to 36-inch frame rails. TCI crossmembers feature all steel construction for maximum strength and durability with less weight than factory parts. Designed with the do-it-yourselfer in mind, these crossmembers offer an innovative three-axis modular design that is adjustable for optimal fitment across a range of applications. Most models also use the original bolt holes, so cross member installation has never been easier. A powder coated finish resists scratches and rust and provides good looks.
