I cant believe the number of people who still dont know you sell 9-bolt parts. I guess they dont read this board very well. Consider this free advertising.

Hey Everyone! Go contact Miles with all your 9-bolt part needs. He's a good guy and can help you out. Support your fellow thirdgenners.

Thanks Kevin,

I am working on a web page (as time permits). Should be up in the next week or so.

3.4x and 3.73's will be available soon (to go along with the new 4.10 gear ratios and the new series 3 posi carriers). I will post when it is available. It will list prices and availability along with pros and cons of the 9 bolt vs 10 bolt vs 9 inch vs 12 bolt.

I have had the 3.73's (not the 3.70's) in my 9 bolt all summer and love them. Nothing like 200+ ft burnouts

Currently installing 3.73's into my 9 bolt (YES, it is a 9 bolt & YES they are 3.73's, not 3.70. I currently have 4.10 gear sets and new series 3 carriers in stock for 9 bolts )

Mile: If you could shoot me a email with your prices i'd greatly appreciate it. Especially for the 4.10, 3.73 and 3.42 gearing.

I am trying to decide on what gears to go with but i am unsure. I do drive on the highway but i also drive in town. Besides that i don't know what TPI vehicles like.

9 bolt? WTF is a 9 bolt? lol. someone please enlighten me, thanks. lil jay

Stock TPI engines seem to perform best with 3.42/3.45 gears. Ones with heads/cam or power adders like 3.70's/3.73's. If you're really into all out racing with larger tires, 4.10's are good.

A 9-bolt is the rear end put into IROC's and Trans Ams from 85-89. Its stronger than the regular 10-bolt, but because it was only used for a little while, it never caught on with the aftermarket. So parts and gears are more expensive and harder to find, than for a 10-bolt.

 

Thanks kevin. I was wanting to put a 218/224 or maybe the LT4 hotcam (i plan on the LT1 intake conversion) but i didn't want to dog out at low rpms especially since at 55 mph i'm at 1400 rpms.
