8 1/4 rear end strength

LOL, yea, with the nitrous, I'd go bigger. The 8-1/4 is tuff enuff for most app's naturally sucking down just plain ol'air and fuel,but that N02 is a whompin power adder and will increase torque right close to the like of added HP it's set up for.

Press a button and a 100 - 150 lbs of torque instantly....that could be bad, 400 ft lbs to 500+, yikes!
