Our steel tubing is laser cut and CNC bent to create a frame made to tighter tolerances than Jeep could pull off back in the day. TDK frames are made from 3/16" A500 steel, which is stronger than the steel used in OEM frames. If you're building a 1976-1986 CJ7, don't spend hours cleaning up an old frame only to have it rust again. TDK frames are the way to go! There are many features included and options available - click below to learn what is possible.
