Nascar 9" gears
Has anyone used with any success Nascar 9" gears? I am looking to try some different gear ratios, and Nascar gear sets, which cost the teams over 600 dollars, are deburred, Rem polished, and treated. A couple people told me at the div1 race last week they have used them, and I was wondering if others have tried them with success. They can be bought for less than 150.00 with one race on them. Once I figured out what gear ratio works best, I would probably buy a pro gear, but would like to put them in for more than one race. I have a super stock car that weighs 3000 lbs with a trans brake. That on a good day will see high 1.30 60ft times.

Having worked in the past for one of the former premier NASCAR engine builders, I got lots of insight on the parts they purchase and used for the teams. They do not cut corners and buy the best. Last edited by SSDiv6; 10-04-2020 at 06:13 PM. |

Re: Nascar 9" gears
I have a set of 6.20 gears I installed recently. As far as I know most NASCAR gears are made by Gleason and new are in the $2000.00 range.Gleason only makes gears in 9310, which is the same as a pro gear.
There were no pinion depth markings or numbers to go by, so it took a little work to get them right.I got the depth close, then used the comet tail on the pinion to dial in the pattern. |

Re: Nascar 9" gears
I bought a center section that had them in it. Odd gear set 4:50 ratio. Ran them for years in a bracket car only changed because I wanted a different ratio.
