I know some of you guys have put the Truetrac in. Any Regrets?

Thank you,

I have 40k on mine and I love it....hardly even use 4wd anymore

 

Nice.

I get stuck on wet grass sometimes..

No regrets at all. Works great for daily use, wet, icy, snow, towing.

 

Rear only or front too ?

I plan to get one this year, but don't know whether to fit it myself, I am capable & would get a spreader, but don't have a press these days, I just prefer to do stuff on my truck myself.

 

Sliced bread and TrueTrac. Honestly, I can't decide which was the better invention.


Wet grass.... ha haha ha haha ha haha.


Ford's factory limited slip in the F-550's Dana S135 axle is a TrueTrac fitted at the time of axle manufacture. GAWR ratings up to 15,000 lbs...if that gives any indication of durability over the friction discs in pickup truck axles having far less GAWR.

 

Rear only. For my use, not much need to have in the front too.

 

Any pick of that bad boy, Y2? Maybe someone here in SoCal don't know they gots a gem, their dumping on clist

 

See the avatar to the left of my user name.

And if you have xray vision, you can peer through the welded on rear cover and see those helical cut anti slip gears in the case.

Otherwise, no, I've never had to disassemble the third member for service, and don't expect to. With the stress distributing mechanical leverage of a 14.2 inch ring gear (current 550s run only a 12" ring gear), and not just 3 quarts, but 3 gallons capacity of synthetic axle lube (that cost over $300 for the lubricant alone, uninstalled, at $100 a gallon for the Redline snake oil I bought), I don't ever expect to have to service this rear end, ever.

Roadranger/Spicer/Dana rates this model of axle as having a 500,000 mile lubricant service interval for on road operation using synthetics meeting certain standards and viscosities.

 

Are there different variations that Truetrac offers? Or is there only one for my axle code V2C34-UA ? I am hoping to avoid buying model x and find out that model z is the way to go.

Detroit doesn't make a TrueTrac for the Dana 50 front axle. They do make one for the Dana 60 if you have one.

 

Dana S135 True Trac. One word to describe them, awesome. I had the smaller version in my Sterling 10.5 and it was great there as well. The strength is determine by the number of pinion group me which in this case has 4. Most others have 3 which is plenty sufficient.

The parts supplier is saying part number 915A567 for the Dana 80.. Is the S135 better, stronger ?

For the front dana 60 any part numbers would be awesome.

Any ring and pinion brands better than the other?

I dont think that I will ever put anything Moog on this truck again. Ball joint failure after 6 months.

Thank you,

Is the Dana S135 better/stronger than the Dana 80? Yes. The Dana 80 has an 11.25" ring gear and is rated up to 11,000 lbs GAWR. The Dana 135 has a much larger 14.25" ring gear and is rated up to 13,500 lbs GAWR with the 135 banjo housing, and up to 15,000 lbs GAWR with the 150 banjo housing, which is 1 mm thicker, but uses all the same internal carrier, R&P, and axle parts as the 135.

There is no interchangeability in parts between the Dana 80 and the Dana 135. So a TrueTrac for a Dana 135 will not work in a Dana 80.

And there is no interchangeability in the Ford dually pick up between a Dana 80 and a Dana 135, without some serious and significant cutting and welding to the axle housing of the 135, which could weaken it, depending on the how the welding was performed, as the axle housing is HSLA (high strength, low alloy) steel. And even then, it wouldn't work unless you ditched the duallys in favor of super singles with a wheel bearing killing dish offset, due to the 135 axle being fitted exclusively to narrow frame chassis cabs.

There are, however, versions of the newer Dana S110 axle that will bolt up to a dually pick up frame, as long as you simultaneously change the springs and ubolt style to go from a round tube to a square tube axle, and as long as you source the 110 axle from an F-450 pickup truck, rather than from an F-450/550 chassis cab. The pickup version of the S110 and even newer S130 axles are designed for the wider apart frame rails of the pickups.

But swapping axles to a 110 isn't worth it. The Dana 80 is plenty stout, and there are more aftermarket doodads available for the 80 than there are for the S110, S130, or S135.
