RE: 3.90's

Motive does and despite what some people might say they are just fine. If you have problems with the rear after a gear swap it was the install not the gears.

RE: 3.90's

I really like the 3.90's in my T-45. right at 2000rpm at 60 mph....Really didn't cut down on gas mileage too bad from the stock 3.27's.

RE: 3.90's

i have 4.30's and love them!!!! i would recommend 4.10 for the conservative everyday driver...the 4.30's are a little steep for the highway, but you'll get use to 3.73's too quick imo
