I hate my GM limited slip. It only works when it wants and now it dosen't work at all. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> I have always had problems with it. Last monday I laid down 150 ft of my right rear tire. I am not joking 150 ft and it never caught. I would go with 3.73. I am about to return to 3.73 in my truck and let GM pay for another limited slip, just because it is free. Good luck.

 

so a 3.73 with the stock locker because i all ready have on or what are you saying dont go with the stock get a eaton and i have 3.42 with 20 inch rims and low profile tires doenst that affect the gearing also should i still put the 3.73 with these rims and tires my radial are the same hight also <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

If the limited slip you have is the G80 Gov-lock you shouldn't waist your time putting it in if you plan on doing a SC later. The G80 might work ok with a n/a motor but when you throw a SC or NOS on, it isn't worth a crap. I plan on putting 4:10's & an eaton aftermarket limited slip in mine in a month or two because I am tired of spinning one tire most of the time.

 

ok thanks so the limited slip doesnt really hold on hig horsepower motor your saying

 

I am saying that the G80 Locking/Limited-Slip hybrid has crappy engagement. It takes a certain amount of wheel slippage between the two wheels to lock the differential down & if your wheel speed is above 25mph it wont lock down either. The differential locks down good on dirt or on wet pavement but absolutely stinks on dry pavement.
