What is needed to be NHRA legal for 10's?
Helmet
6? point Cage
Drive shaft loop
Fire jacket
Axels? What's needed there?
Long wheel studs?
SFI bellhousing?
SFI harmonic ballancer?
Are stock seatbelts no longer legal?
(this is for an automatic car)

This will help with some basic answers,but it really needs the rulebook to be fully understood. http://www.nhra.com/tech_specs/ETQuickRef.html
As soon as you get a rollbar,you need 5 point harness's. Stock seatbelts dont cut it.
There are others with the rulebook closer at hand that can answer these questions........i cant find my rulebook.

Erik,
Helmet should be a SNELL 90, 95.
6 point minimum, if you still have factory floors, firewall, etc.
Drive shaft loop.
SFI spec.3.2A/1 jacket.
Aftermarket axles and c-clip eliminators.
The studs have to be long enough that they are into the hex portion of the nut by at least their diameter.
Bellhousing SFI spec. 4.1.
Balancer SFI spec. 18.1.
Seat belts SFI spec. 16.1.
An interesting note is that to run Stock Eliminator some of this stuff is not required.
I hope that this helps,
Daren

A transmission shield meeting SFI 4.1 and must pass under as well as over the transmission ie two piece trans shield, one piece with pan thet meets 4.1 or blanket type.
A window net meeting SFI 27.1
Everything else listed by daren is correct

Cage and net needed with stock floor/firewall iff it runs 135mph or better. You need a chute then too. Don't have to use it, but you have to have it. I think an electrical shutoff switch is needed as well....regardless if you run a relocated battery or not....(that one I'll have to look up).

With stock flooring you can get by with a six point weled bar, but it must meet cerain cleance requirements. With a bar you don't need a net. With a cage, a net is required.
My advice is to buy a rulebook first. Also, IHRA and NHRA have slightly different rules if you want to run at dfferent tracks. Some tracks have their own "house" rules too that you need to take into consideration.

of what we did to make our car legal for 10s. We installed a cage to strengthen the chassis, and a window net. I checked the rule book and overlooked the cage/roll bar requirement. Oh well thanks for the correction
