Sterling vs d80

[BogginF350]

We made around 30 hooks with my truck and never broke a pinion. I did break several axle shafts and rear lockers. I have seen pinions break but all those they were where on trucks that did not have traction bars. They don't hop, rear axle moves ahead and pops the pinion. The best video I have seen of this happening is linked at about the 4:25 mark. I also want to say that I will be swtiching to a dana 80 for the added strength and availability of parts. But I don't think the sterling is junk, just not as strong as the 80.

Where I pull the classes have no ladder bar or traction device rules.

Mad dog put some aftermarket parts in his sterling hardened pinion shaft ect. The sterling has about the same sixe axles as the D80. In a rare case a pinion will break from bounce upgrade the pinion and it will hold every bit of what an 80 will. Ring gear size don't matter. LOL look at the 9" ford rear end's in the dragsters.

The AAM has a weak carrier I have seen some 14bolts clean out the front side of the rear end.

The dana 80 has custom 37 spline billet hardened two piece axles with drive flanges available.

I have a richmond 9 inch gearset in my 79` shortbed. I have sheared the pinion and ring gear teeth off 3 times. Moser nodular case, mark williams spool, mark williams support and moser 35 spline axles. Also blew the MW pinion support apart last time.

where do i get a hardened sterling pinion shaft or is that something you have done to the one you have

Don knock the 9" - it has bigger axle shafts, pinion etc than the dana sixty, and the same size axles as the dana 70 at 31 spline and unlike most rear axles has a third bearing on the end of the pinion for support

Bounce will kill any rear axle sooner or later - usually sooner, so will repetitive tail wagging ( leapin off the line with all you got)

stix are harder than autos on parts, especially slider clutches that hit hard about 75-100' out

You dont just buy a hardened pinion shaft, you get a heat treated gearset. Aka richmond/yukon etc.

nah - i will go back to heat treatin my own like we did in the gasser wars
The reason many break aftermarket gear sets is they are too hard - we used to take em to a shop in town n have em heat em a liitle to bring the rockwell down some
rarely broke a pinion or chip/break teeth after that

well I hope so Because I replaced everthing in the front and rear axels with yukon 456`s with Tru-Tracs..... I dont sled pull Im just into tug-a-truck....

GUYS! GUYS!!
MADDOG HAS SPOKEN!!!:bow::bow::bow:

End of discussin, the rest of us are morons.

So evidently you ALLL have more than 1200 hp, or MADDOG......doesn't. LMAO!
Happy 2008, upset puppy!!LOL

The Sterling 10.25 is not junk. I did not say it was a good sled pulling axle because I have zero experience pulling a sled. I do not have any super dooper parts in my 10.25. Detroit locker, 3.55 gears, and 1410 series yoke. to date I have broken one shaft and a detroit locker.
I think you know Gene that I have not pulled a sled, and where did I call you a moron? There are plenty of videos out there of races that show what I have put my truck through. You can dispute the horsepower all you want Gene, but please explain to me how a lifted 7000lbs 4x4 crewcab can pull a 6.48 @109mph in the 1/8? I use the 1/8 cause other things break in the 1/4:doh:
IMHO the 10.25 is better than the 10.50, and the 10.25 may not be good for sled pulling, but it is far from junk.

Please tell us what you have done to yours to make it live. I have asked you before and never gotten an answer. I have less power than you and have broken 3 10.50 dually rear ends. 2 pinions 2 rear ends and both axles in the other. I have ordered new ring and pinion, but where do you find aftermarket alloy axles for these?

moser $300. 1541h i think. i pulled minie for 3 years with no problems other than yokes. i went with a fixed flange and so far its holding.

Thanks Joe

Mine holds up fine till it starts to carry the front wheels around the 280 mark. 35 inch boggers and 680rwhp is a recipe for disater.

here are a couple I have handy

haha Maybe its my injectors, both of those trucks were running my 180`s LOL
