GM A-Body Weld-in Tubular Frame Kit (66-72)
PTSfab weld in frame kits are here! If you are looking to swap in an engine combo that needs extra room or you're trying to just have extra room for ease of maintenance, this is the ticket. Fully tig welded and constructed of Chromoly. Turbo systems, larger headers, dry sump accessories and large oil pans are all difficult swaps for these older chassis with the stock bulky center section of the frame. these kits do not require cutting the factory frame rail at all which also is a legal modification for most true street and other limited street classes that do not allow "tubular front"
All factory body components can be installed as they were, no guess work!
- Allows room for any engine combo
- Full access to oil pan
- Accepts ALL aftermarket control arms
- Chromoly construction - fully tig welded
- Requires motor/mid plate for engine mounting
- Saves 18lbs frame kit only

Our DIY Universal Motor Mount Kit was designed specifically for the guys running our tubular weld in K members that can’t or don’t prefer to run motor/mid plates. This Kit is a “you-weld-it” setup that allows full custom install and desired routing of the lower support bar for clearances around specific oil pans, exhaust being ran past the engine, larger header primaries, etc.
