4x4x1/4-in. Tubing

Our Goal/Intentions

Our Goal/Intentions


As an economical option. A single piece of 4x4x1/4-in. steel tubing may be used as a FRONT bumper. The tubing must be straight across. No bending or welding of any points, angles or sharp objects. Must be able to see into the ends of bumper. Do not wrap the 4x4x1/4-in. tubing with a factory bumper or bumper skin.

Our Goal/Intentions

We understand good bumpers are expensive and becoming hard to find. The options listed above are intended to give drivers/builders “low” budget options that are comparable to a factory automotive style bumper. Neither of the manufactured bumper options listed above are expected to be stronger than clean 74-76 Chevy or Chrysler bumper. 

In order to have a manufactured bumper approved, we must talk with the fabricator and see the unit in person.  

Homemade bumpers are not permitted, for the simple fact that most builders cannot follow simple door plate size and spacing rules.  

If you have the capabilities of making an exact replica and we can not tell the difference, then go for it. If we do see a difference, don’t get mad when we tell you to cut it off. This is your one and only warning.
