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 CJ, 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.
