Not to barge into this thread but has anybody ever "spooled" their 7.25 and what were the results when you did? I've heard of a lot of off road guys doing this not sure how it would turn out on a street car.
I've heard of them snapping/twisting axles in street cars. maybe something big and strong and you would be okay but I think you would twist or snap a 7 1/4 axle.
