I was running a rear 70HD on my pulling truck. At my last pull, right before the 300' mark, I ended up twisting off the pinion gear right at the end of the yoke. I'm planning to upgrade and thinking about a Dana 80. I've located an 80 out of an E350 with 35 spline 1.5" diameter axle shafts. Are any of you guys breaking gears or shafts on the Dana 80's with 35 spline (1.5" shafts) or 37 spline (1.6" shafts)? Is anyone running upgraded / aftermarket shafts in their 80? -thanks-
14 bolt axles aren't as strong as an 80 but the 80 has a weak pinion yoke in comparison IMO. Seen two of those break off, one damaging the pinion gear, never seen a 14 bolt break a pinion yoke. Never seen a sterling break the gears...axles though will break. I personally would rather break a shaft than anything else in there, but ideally of course would like to break nothing. Could always upgrade to militarys

I run a 14 bolt in my stock pulling truck. Never have had a problem. It was in the truck when I got it. The PO said he was breaking 70s all the time. 14bolts have gotten so cheap around here[200 to 300 bucks] they just seem a good option.
