The stock Mopar cast steel cases are way stronger than any cast iron, nodular or cast grey iron, cases out there Don't waste your money If you want to make a positive change for your 8 3/4 to make it stronger buy one steel carrier cap for the drivers side and have it install by a good competent machine shop That or put the money towards a Dana 60 Mr.Cab Racing and winning with Mopars since 1964.

I had been looking at the Mark Williams cap, but when I ran across the Yukon cases, I figured it was worth some research. I'd love a Dana, but it's just not in the budget right now. You'd poop your pants if you knew my vehicle weight and the HP I'm putting thru the 8 3/4, BUT it rarely sees the track, especially now that I'll need a license, 10-point certified cage, etc...

I have been running this one for four years. I was thinking about adding a little more power and the 8 3/4 makes me nervous. 67' charger 499 RB 10.57 at 127

I have been running one for a few years with no problems other than when I got it it had a lot of casting sand stuck up in the pinion area. It has held up fine, my problem is ring and pinion life.
