Thanks Mark. I'll look them up, although I can see already form their website they look very overpriced when it comes to the gears compared to othes I have seen. (http://www.buyfordracing.com/shop/pr...roducts_id=461).

Unless that includes everything needed for the install they seem high.

I've been dealing with www.joeheckracing.com . They have their work done by www.bigdaddyperformance.com .

The guy from joeheckracing says get 3.73s, but when I contacted the owner of bigdaddyperformance he said go with the 4.10s.

 

So I guess we are like brothers now since I have the same MOTIVE 3.90's and no whine. I love them!! Much better MPG than 4.30's ill tell you that much and not much of a performance trade off on the street. Did you change out your diff when you did your gears? I went with the Detroit TrueTrac and its awsome.
