Default Roll Cage

Local dragstrip requires cage on 11.49 or faster and since down to 11.61 on best run, gonna need roll cage soon. Are kits available and if so where. Crew cab truck. 2007 and up can go to 10.99 before cage, thought maybe just put 2007 since they don't check.

You read that wrong. A truck can't go to 10.99 before it needs a cage, that's reserved for factory cars that can run that time without any supporting mods. You still need at minimum a 5 point rollbar under 11.49 and at 10.00/135, then you need a cage, and NHRA license.

As far as kits, I haven't found one that fits worth a shit. Have it made for you is going to be your best bet.

Thanks for clearing that up Old Man Tan! Still hoping someone will chime in and know of someone that makes a kit! What are the required specs on the piping used?

Can the cage be kept in the cab or does it have to extend reward? Sorry for the dumb question but I know I'm not far off myself.

an extended or crew cab truck would be able to keep the cage in the cab as well. at the end of the day, work with your NHRA tech/inspector. he will be the one with the final say and have the highest discretion on how the cage can be built. the rules in the NHRA book are a guide line, safety is the main factor to the tech as well as proper build.

i have not seen any cage kits for these trucks but then again, i never looked for one. i built them instead

Mark's reg cab has a roll bar that passes tech without exiting the rear? If so, I need pics so I can do the same.

Correct, however, I was under the impression that it still had to utilize the rearward bracing to the frame. If there is a loophole, I am all for it so I can keep a street appearance. Otherwise I will just do a full 10 point cage if I have to send bars out the rear regardless.

The “roll bar” rule does not require any minimum angle degreed bars to face rearward. I bought the truck that the bar came out of that’s in marks truck it had side bars, main hoop behind the seat and then two bars 6” inside of the main hoop bars and they also went through the floor. 6 tie ins to the frame total. I’ll text mark tomorrow and tell him to visit this thread and comment pics.
