8.25 and slicks?

I post a lot in the car forum. You just missed it. To answer the question we need to know if it's a sure grip. I assume it is but need to ask. The weak link in the 8.25 is the spiders. a sure grip will help to alleviate this. Somewhat. They're not a whole lot weaker than the 8.75 if at all. The pinion is a larger diameter than the 741 case 8.75 too. Next question is what size slicks? I have ten and a half inches on the ground. Next question. What transmission? If it's an automatic, what converter? For reference, I have an automatic with a 3500 converter. The biggest thing that nobody ever considers is the gears. The lower the gears the less strain there is on the rear end. Think of a three hundred set of gears and a four hundred set of gears. Just for reference. The four hundred set of gears needs the engine to rotate a full revolution over the three hundred set of gears to get the same tire revolution. Therefore the rear end takes twenty five percent less abuse. with the 4.00:1 than it does with the 3.00:1 ratio.
To answer your question directly, you'll be fine. I've driven mine like I hated it and wanted to kill it. But it's never even hinted at wanting to quit.
