7s rear axle

tried to find the answer but lost my rulebook, would a ford 9 inch on a toyota 7s be legal for score?

This is out of the BITD rule book online. They run basically the same rules as SCORE (other than motor rules).

SCR26: Transmission

Any transmission that is listed and delivered by the manufacturer may be used.

Any shifter may be used.



Differential
Front differential must remain original stock, with the exception of gear ratios, as delivered by the manufacturer. Materials may be added for strengthening purposes only. Front differentials, including traction beam type, may be reinforced.



Rear axle assembly must use standard concept automotive production housing and third member. Gear ratios, carriers, axles and floating hubs are optional. Must retain stock track width plus or minus 2 inches.



Knock-off hubs are not permitted.

I pretty sure the 9" is legal in 7s. I think Fire Guys Racing runs a 9" in their Toyota and have been pretty happy with it (I think I read that in another post on here). You might contact them and ask. Jason Hutter (Fire Guys Racing) is usually pretty active on the site and will probably help you out with any questions.

Yes, a 9-inch is legal, I run one in my truck, however the width is limited to +2" over stock.
How about that 13 second victory in the CODE Class 7s! The side by side racing the last 30 miles doesn't get any better.

yes-you can run the ford 9" in 7s, but you can also stick with a toy 8" and be just as happy. the axles of the 8" are actually beefier than a stock 31 spline 9" and you won't have to have it custom made to meet rules width. parts are easy to get and it uses a drop out center section just like a 9". you won't be sorry.

I use to break toyota rearends the one ton ones at that.Then I switched to a Currie 9 inch and no more problems.Over four years of racing and flying with no problems.Well worth the money tell Ray I sent you.

thanks for the info, i already bumped up from a 79-85 housing to a 86 to get a little more width. i haven't had a problem with it yet but a few of my buddies have bent and broken yota housings. belive it or not i found a complete 9", drum to drum third member and everything, 31 spline on the side of the road. they were doin a neighborhood cleanup in south sacramento and it was in the pile goin to the county dump and i snagged it. so now i'm debating whether or not to put it in when i get back to the "world".

yeah there is a ready to go weld on truss for a 9" on www.bajaconcepts.com. i think currie or somebody actually makes it but it's only $80 and would save a lot of time. if i decide to put that axle in i'll probably put that truss on first.
