8 3/4 goes boom
I was very anti dana for quite some time. Now it's the only thing I'd run if I had to drop a nickel into a rear end.
Round about numbers for a complete with brakes Dana vs. an 8.75 that will handle big hp. 3200 vs. 5200$.
I needed to upgrade axles to go to SBP to LBP, you're already looking at 400$ or so. Then you'll need brakes. I'm a disk guy so lets say 500-1000. 750 average. now if it's for a show car you'll need to have it painted or coated. There's another 100 at least. That's assuming the stock parts will work and hondle your HP which in many cases, tey wont'.
So you're already over a 3rd of the way to an ideal width dana that will handle 1,000hp all day long and look great doing it.
Deduct what you can get for your 8.75 the new dana costs you about a 1,000 or so net cost.
