My next build I’m going all out and making it as lite as possible. Starting with a 7 1/4 rearend and upgrading it with unobtainium 4 bolt 3/8 aluminum stud axles. I’m going to flycut the ring and pinion thinkness and make up the thickness difference with Old Milwaukee beer cans. I’m going to save more weight and drag by leaving the rear cover off so I can spray the ring and pinion down with Pam cooking spray before each pass. Looking for some new bests in 2019 can i watch ? Only if you bring the beer and the Ben-Gay. And YOU have to apply the Ben-Gay. I am not applying ANYTHING to his rear end

We're all going about it wrong. An 8.75 is the best rear ever. It's just that no one ever sets them up correctly. Finally some words of wisdom.... I feel so silly with a dump truck rear in my lil small block Duster. What was I thinking!!

I think the consensus here is the 8 and four quarters brand nuetral racing differential is the best.
The dump truck differential fit my budget best though

I wish I had the money my Son Matt thinks he has. His plans are to go from an 8 3/4 to a full fabed out ford 9 inch. I wish I could afford one. Two Dana’s and a modified reenforced 9 inch in my junk.

Rick Jones gave me a tour of his Pro Stock trailer one time. There must have been 10 chunks lined up in there. I asked him why and he explained why they have to change ratios if the air density changes. Pro Stock is so sensitive. I prefer a class where you just build your car and go race. And have a good time.

Were is the weakest link in a Dana 60?
I compared the two bearing caps from a 8 3/4 and a Dana 60 that I have, we already know that the cap on a 8 3/4 is a weak link but how hold it up on a Dana 60? It looks little weak to look at?

The only thing I've ever done to make them better (all I know) is obviously the shortest flange, to flange width you can work with helps keep it from bending the tubes forward, and putting a Mark Williams cap, or something like it on the left side carrier bearing since that's the one that wants out under load.
Herb McCandless built my last Dana for me and recommended the MW cap on the left carrier bearing as well, mostly because I intended on using a transbrake in the car. He said that the extra load from the brake turned that bearing from an "if" to a "when" it would break. He said the MW cap on the other side definitely wouldn't hurt, but it also wasn't overly necessary. Other than that, good axles, a good spool, good Spicer bearings, and a good Pro gear is a recipe for longevity for what most people here are using their cars for.

For sure the quality spool if you're making power. The moser spool chops the shims in two because it has almost no landing shoulder for the shims, and the radius of the bearing corner cuts them. The strange, and the mark williams are the only 2 I've seen with enough.
I get as low as 1.16 60's in a 3400 pound car. Normal is 1.17 to 1.18 depending on track conditions. I had a moser spool, and stock caps, and every 10 runs or so the whole set up would be loose. From the pinion preload to side clearance. After the strange spool, and a williams cap it stays right where I put it, and the pattern doesn't crawl out as bad.
I also think the only gear company that gives a flip about accuracy with 60 pro gears is/was Motive gear. Richmond must make them on a wooden bench, as well as US gear. Just rolling the gear around you get different backlash readings. Motive was dead on at any position. Forget lapping the back of the gear with a stone too, it just gets worse. Motive gears, I'd take out of the box, make a couple passes with a stone, and they'd clean up instantly.
The pro gears bend, and take a set anyway, so I guess it doesn't matter, but it's annoying during set up, playing pick a spot.
