Personally I like the 6.14 ratio. :o

Ford 8.8 Performance Gear Sets


Motive Gear has added six new 8.8-inch gear ratios to its industry-leading ring and pinion line, so you can fine tune your differential for faster and stronger starts coming off the line. The company is now offering 3.90, 4.30, 4.88, 5.14, 5.71 and 6.14:1 ratios. These go along with the 3.08, 3.27, 3.31, 3.55, 3.73, 4.10 and 4.56:1 ratios currently being offered.

These new ring and pinions fit the 8.8-inch Ford rear axle, but Motive Gear also offers 3.31, 3.55, 3.73, 4.10 and 4.56:1 ratios for the 8.8-inch front axle.

Motive Gear is one of the leading manufacturers of drivetrain products for the performance industry, including ring and pinions, axle shafts, cases, internal kits, spools, housings, bearing kits and more. Motive Gear also produces assemblies and parts for foreign and domestic standard transmissions and transfer cases.

 

3.90s seem like a good compromise

 

damn, thats kinda cool, but it adds a bit to my dilema. I'm trying to decide whether I want to go aluminum 9" vs 8.8 with 9" ends on it in the Pinto. I'll probably go with the 9" because of ultimate strength and used parts market, but that is very interesting.

 

You can make a 8.8 almost as strong as the 9's anymore. Plus the 8.8's are cheaper to find and the parts are cheaper. Not to mention the invinite aftermarket for the 8.8's.

 

I agree, but by the time I go through all the trouble of putting the 9" ends on the 8.8, the 9" becomes an attractive option. Plus, I have a feeling that an aluminum center section 9" will be as light or lighter than the cast iron 8.8.

 

Only good thing about 9" is you can change out the gears quite easily
