5 Stars   Almost the perfect kit
By on 5/9/2014
I bought this kit and while everything about it was flawless. It did need some extra pieces that I had to buy that possibly should have come with the kit.

for instance, I needed these after I discovered my ABS rings where completely rusted into place on my old axles. http://www.latemodelrestoration.com/item/LRS-2189A/94-04-Mustang-Rear-Axle-Abs-Reluctance-Tone-Ring which clearly states you should buy these when replaceing your rear axles.

also the lugs are about 1.5" longer than your stock lugs so you will need to buy long lug nuts or in my case some high grade open end lug nuts. I guess the lugs are made for people that run all kinds of positive or negative wheel offset, but still a set of nuts would have been nice to have and would only add about 15 bucks to the kit.

Yes, I would recommend this item to a friend!

5 Stars   All the Accelerations!

I got this whole kit installed professionally so I can't comment on the components other than they are trusted. No whine out of the gears, acceleration is solid now, throttle feel is amazing through every gear. This is the way mustangs should have came from factory. Mine is paired up with a 425HP supercharged 4.6 2 valve and it woke it up.

Yes, I would recommend this item to a friend!

5 Stars   Exactly what I needed

Owner before me put 4.10 gears in the car. I opened up the rear cover and noticed the ring gear was flared out from not correctly setting the pinion which resulted in slack in the ring/pinion clearance. This package fixed everything and the new rear cover is incredible. Highly recommended.

Yes, I would recommend this item to a friend!
