I have a 9bolt rear with 3.27 gears in it. I am wonder what is best gear choice for gear's and where is least expensive place to get them. I drag race this car and only going thourgh the lites at like 4600 rpm. I also drive it on the streets. any help would be great.

 

what is your trap speed and tire size?

 

My trapp speed is 101 mph and My tire size is about 25.5". I am night quite sure on the tire size. I am using a 15" rally with like a 245 50 15 tire. I will be getting some good drag tires and rims soon. Some pro stars maybee. I will proabally ask about that to when I am ready.

 

with 3.73 gears and u should hit around 5.1 - 5.2k rpms. should be good for a tpi setup. if u run taller tires such as with drag radials or slicks, u can get more gearing out of it.

 

So 3.73 is good choice and is still drivable? What is best place to get them? This for the 9bolt.

 

now thats the tricky part, finding parts for a 9 bolt. can't help u there. but from where u stand now and in the future, 3.73 gears would be perfect for you.

 

Thanks! Any one know where to gears.

 

...for a 9-bolt the available ratio would be 3.70. - try reider racing or randy's ring and pinion. I heard Yukon now makes a 3.70 for the 9-bolts.

 

Not sure if he's still in business but try www.diffsolutions.com 9 bolt parts are hard to find. If you order from Australia, you can get lots of stuff since that's where they're made.
