Going from 4.56 to 5.13 gears on super 35 axle

[connor grimes]

Looking to re-gear to 5.13 gears after running 4.56 for awhile. Current set up :
Dana 35 w/1541H revolution shafts and e-locker. My question is can the dana 35 accommodate 5.13 gears using my existing e locker and axle shafts? My gear shop is hesitant to install as they said higher than 4.88 is risky given the smaller pinion. Thanks in advance

If the existing locker can fit 488, then it can fit 513.

Your shop is acting on outdated fears. The lower axle gearing places less stress on the pinion because it has an increase in mechanical advantage.

Both 4.88 & 5.13 gears have a 7 tooth pinion so I'd ask your shop why the 5.13 gears are weaker than the 4.88 gears. Your 4.56 gears have a 9 tooth pinion gear.

I am unsure what the e-locker carrier can fit

RGA offers them with 513

I bought my 4.56 gears from revolution maybe 30k miles ago, is it worth buying the whole gear and bearing set or can i just buy the ring and pinion, assuming the bearings are still fine

That is a question for your gear shop. I suspect it would depend on the terms of their warranty.

I would still want all new bearings if you're installing new gears. 30K miles aren't a lot but I'd still want to replace the bearings if for nothing more than piece of mind.

This,if a shop insists on ordering Yukon instead run away.if THEY won't order what you want then they can squirm out of a warranty

Damn - I wish my 14-bolt knew this…

As stated by others, the pinion on 5.13 is the exact same size as the 4.88. Both pinions have the same tooth count with just slightly different tooth profiles due to the different tooth quantities on the ring gears. The teeth on the 5.13 setup actually will endure less stress than 4.88 at all times due to the mechanical advantage in their favor.

Unless the bearings are worn (unlikely with 30K), there is no real need to change them either. I'd do whatever the shop wants.

Whats wrong wit Yukon? Literally every set of Yukon gears I have personally seen have all been circle K

Machined like shit, vendors don't stand by the product, IME

Has it been a while since you've seen a set? Pretty sure they stopped using Circle K and switched to their own China made gears around 2020 or so. Before that I think they were all Circle K like Revolution and most of the others.

I have to admit, its been a few years since I have handled a set of any brand lol. Personally I have used Revolution once, I typically use Motive and have never had an issue, but all that may be all out the window

It seem Yukon has gone downhill in the past 5+ years. lBasket just tried to install a set in his HP30 and couldn't get them to install due to the coating or something on the pinion gear. Ended ruining the threads on the pinion.

At a minimum I would at least replace the pinion bearings, it's too easy to mess up the cage removing it from the shaft. The carriers should stay in place so if they look good I'd let'm ride.

Sadly I had a similar issue with a Revolution set as well, or at least I think it was Revolution. It was extremely difficult to get the outer pinion bearing on and off of the pinion. Hammering the pinion out to set up again was terrible. Ended up stripping the threads on the pinion nut one of the final times I went to set the preload shims.

Was it this hard to get it out of the housing? Lol.

I never even got the yoke fully on to do this

Yep....I bent up multiple punches bad lol. I got the yoke and bearings all the way on and off but man it took a lot of hammering. I probably brinelled the setup bearings in the process. I forget whether I used Koyo or Timken during the setup but whatever I used during setup, I used the opposite for final assembly. The final assembly was super easy so I think all along, my problem was more the bearing than it was the pinion, although the first pinion was for sure the worst, so probably a bit of both.
