Power loc vs track loc ?

[bax]

I have had good service out of both. The track lock seems to be easier to find. The Power loc I'm my opinion was a stronger unit. So I started looking for another one to set up my high pinion 44. Not much luck finding them. Did Dana stop making the power loc? I can't find one for sale new.

If you’re going to run a LSD, why not opt for an Eaton TruTrac? They work better than any of the others and being mechanical, do not require maintenance or special additives.

Bronco is 70% street. I have no experience with a tru track. They look interesting with the worm gear set up. They are more money. I am used to the clutch packs and completion clutch packs. I have never had a real problem with them. The additive is not a deal breaker. The only power loc I found for sale was at Toms. It's 400 the tru track is 500. That's not a huge deal either. But that slippery slope at 500 is pulling me a Detroit at 650.

Trutrac has great street manners as the say

The Power Lok has cam wedges that put extra preload on the clutch pack when under throttle. It slips easier when coasting and locks harder under throttle. The Trak Lok is constant clutch preload.

Track Lok cross top, Power Lok bottom.

Thanks for the picture. I was under the belief that the power lock was a little better. IMO by the description you gave the power lock is the one I am after.

The power loc was a pretty common factory option in Scouts. Were they ever factory in the Bronco? Would a unit sourced from a Scout fit a Bronco D44?

The trac lok is different than the power lok for the reasons listed above, AND the trac lok is normally a two pinion, single piece case and MUCH weaker than the four pinion, two piece case power lok.

(There are a very small number of two piece trac loks with four pinions, but they are few and far between, and are normally believed to be power loks...so be careful.)

Dana Spicer stopped servicing the power lok many years ago, but fortunately the aftermarket has reproduced the entire assembly, and they are still available.

Depending on your gear ratio, I have both a trac lok, and a power lok for the Dana 44 in your Bronco. Send me a PM, or e-mail jamesroney@yahoo.com

I have nearly 30k on True-track, I love it! great street manners. Zero noise. Also 9" True-track is only one with preload so when you have rear end up in air you cant spin the wheels. Its more aggressive than factory trac-lock setup that really only works in slickest conditions, and will one wheel peel on dry pavement. (had the four pin trac-lock in my Aussie XB Falcon) The True-track gives me second gear scratch (c4) both wheels with 31" tires on dry pavement. If I had the money I would put it in rest of my Ford classics.

I had a Power Loc in my Dana 30 for years and I loved its aggressive locking ability. And as others said, it had 4 spider gears instead of 2, that I was told Trac Loc had.

When I built my HP Dana 44, I was looking for another Power Loc for it, Tom's uses them in their 44 Mag Dana axles, and they sell them separately for the best price I saw, under $400.

However, I too decided on the Tru Trac for my HP 44, due to all the positive reviews here on Classic Broncos, even though it is a little more money. And finally the shop owner that set up my gears, does a lot of modified Jeep gear changes made the statement that the ones he does using the Tru Trac don't come back in with broken parts because the True Track transfers the torque between sides smoothly and without the shock loads the Power Loc has from its aggressive nature. Especially important using big tires.

So far, I too, love the Tru Trac.

well they have one less now. I bought one late Friday. I do appreciate the good information everyone offered up. The bronco I am putting this in 70% street so the off road performance won't be tested that often. I just did not want to put it back together with an open front axle. saved a little money for the rest of the build. I believe the power lock was a good option for my purpose. I have no doubt the true track is better but I am good with my choice. Thank you all.

Nice bax!! I've often wondered how a 31 spline 9" wavetrac in the rear would do with a front powerlok, for mostly a street rig.

They even sell a 35 spline unit, so I figured they may be designed pretty stout overall.

Those are interesting.
