I got a 99 v6 3.8 and need some power in the rear. Im looking at a ford racing 7.5 spline traction LOK limited slip diff. on americanmuscle.com. as what i hear the v6 requires the 7.5 28in tlok system and 4.10 (7.5) gears.... i can NOT find ford racing gears to match the tlok. if anyone knows where i can buy them on line id be very greatful. also are there any risk of using a diffrent brand from the T-lok. such as these Motive Performance Plus 4.10 Gears for 7.5in... Gears are the way to go for a v6 esp for one of your 1st mods, plus getting it tuned. any ideas guys ?
