Most reliable ring gear for GM 8.5
 

What is the most reliable gear for a GM 8.5 at the moment.. Currently have a 4.56 Richmond but heard they have moved everything across the pond.. No one makes a pro gear for an 8.5 so I guess I need the best street gear going right now..

Fleming,

what is your application and performance level?

Motive of Italy bought Richmond, whose tooling was worn out--at least that is what I heard. I have had good results with Motive gears from Italy. A good set will have no more than .002" runout around the ring through several revolutions so each pinion tooth eventually hits each ring tooth.

Fleming,

What ever you get make sure it is made in the USA !!!! The other stuff won't last 10-15 runs !!! Ask for only USA made , don't waste your Time or Money ??? You can tell by the price if there made in the USA , its always more money.... But well worth it, unless you like changing gears every-week ?? Do it right the first time, its always cheaper in the long-run.
Good Luck & be smart ..... Motive, made in Italy/ Germany is an excellent sub for USA made ....

Fleming,

Strange [and I expect others] sells the U S Gear brand. I have installed several of that brand with good results and good service life.

If you want extra insurance you can have the gear set Cryo & REM treated at a cost about equal to the gear set.

Also, considering your application and it's performance range the out of the box gear set will most likely give acceptable service.
