Roll Bar/Cage

[Pushit2.0]

PM for pricing on a main hoop if you want one. I have 1 5/8" .083 chrome moly or 1 3/4" .083 chrome moly and I might have some 1 3/4 .125 mild steel.

The 1 3/4" pipe either mild steel or chrome moly is used for your 5/6 point roll bars. The kits they sell are normally called 8 points because they include the "d" bars which are only used for the 8 point roll cage, you can install them but they are not need to be legal for NHRA/IHRA.

And the 1 5/8" either mild steel or chrome moly is used for the 8 point roll cage, the cage encloses the driver where the roll bar does not.

And welding chrome moly for NHRA you need to use a TIG welder on any chrome moly or chrome moly mild steel joint, and you should use ER70s-2 welding rod, and DO NOT stress relieve the welds. You can still use a MIG welder for welding the 6 x 6 plates to the chassis but for the plate to the pipe you need to TIG.
