Designed for a 1-3/4 x .134" wall side-bar tube. This kit allows a roll bar side bar to swing open by using a weld clevis and weld tab on the upper end of the side-bar and a weld clevis and weld eye bolt with bent tube on the lower end. The bent tube allows you to align the side bar to the correct angle, and weld it to the floor plate. Simply remove the spring-loaded pin at the top and the bar can be swung open making entry and exit easy. Kit includes all parts to complete one side bar. NHRA accepted.
