So i finally got around to swapping my rear today. After the KB install i wanted a little more pull at the top of the gear so i was thinking of swapping to a 3.73 but then found a complete rear with 3.55's. The rear was mint with minimal surface rust. But i still primed and painted everything black.

primed



mountaineer diff cover modded to fit. (thanks for the write-up TOB)



fresh paint



stock rear



comparison



new rear installed



new cover






the new diff cover is a tight fit with the BMR panhard but there is about 1/4" maybe a little less of clearance. It took me about 3 1/2 hours on a lift taking my time and b/s ing with dave (daffy) and my dad while working. very happy with how clean my undercarriage looks now.

And now the car really pulls like a freight train with the KB on it. I was shocked at the difference b/w 3.31's and 3.55's. It just keeps pulling and pulling. Very happy with 3.55's and seems to be perfect for street driving.

I have always felt the same way. Given I don't make your type of power but still a very decent amount I love the 3.55's. I went to a 4.10 and as soon as the SC was on all the car would do was burnout making 1st useless and most of the way through second. When I went back to the 3.55 the car now just does a really loud one to two second screeching burnout and it hooks and is gone. I could see having those big gears if you have drag radials and are at a track but I think they useless on the street.

from a dig i wont hook till mid or top of 2nd with the roads and tires hot. If from a roll and drop it into 2nd it dead hooks or might spin just a tad. LOVE THEM!
