About Our Frames & Chassis

Custom Welded & Renovated Hot Rod Chassis

All of our frames are built for durability, function and form. We duplicate the shapes and contours of the original frames as much as possible. Our construction style doesn’t stretch the wall thickness thinner, unlike mandrel-bent tube style frames. They also don’t require being stress relieved to keep the material from trying to go back to its original form, which is straight.  .

When we add our suspensions and rear ends, we can recommend tire sizes, wheel widths and backspacings for all of the proper clearances needed for your vehicle. If you are also purchasing the 3rd member with our 9″ Ford rear end, we can also recommend what the best suited gear ratio for you drive train. Included with every frame and chassis is a Parts list.  This tells you exactly what parts are used on you frame, to make maintenance simpler. It also helps the resale value of your vehicle. Have you ever bought a customized vehicle that you didn’t know what brake caliper the builder used when it was time to replace the pads?

  Do you want you vehicles extra low or at stock height? We can custom build your ride height.
