Trying to decide on trac-lok or Yukon Duragrip

[ChrisTJ98]

I know about the truetracs but not really wanting to spend that much for one. I don't mind having to rebuild the limited slip and don't mind having to add the friction modifier.
This is basically all stock TJ may try and squeeze some 32s on it. Rear is a dana 44 from a LJ I am rebuilding. Probably going with 4.10 gears. I've read more issues with duragrip failing then trac lok, who knows what kinda abuse they put them through as well. I don't really see a difference from these two limited slips and trueurac other than they will need rebuilding at some point hopefully around 50k as I don't plan on going off-road much but you know how that goes . So saying all that am I basically right it doesn't matter what you do they all perform close to the same with these three limited slips ? This is probably a Yukon question for them but do I understand this correctly a 4.11T meaning THICK is made for if you have a carrier that is 3.73 and down and if you buy any carrier 3.92 and up a 4.11 non Thick is needed?
I'm curious now with my dana 30 front axle being a 3.07 gears that can I install a 4.11 THICK on to that carrier being open so I don't have to replace the carrier ?

Thanks
Chris

Your Dana 44 Tracloc carrier is good for 3.92 and higher ratios. Higher ratios mean 3.73, 3.55, and 3.07. Any ratio lower than 3.92 which includes 4.11, 4.56, 4.88, etc. will require a thick gear set. Being 'thick' just means the ring gear is thicker so its gear teeth will closer to the pinion gear so it can engage the smaller diameter pinion gear that comes with a lower ratio set of gears.

You really don't need to add more friction modifier for a Tracloc with 99% of the GL-5 gear lubes on the shelves. Look on the back label for words to the effect of 'Compatible with limited slip differentials' which means it already contains the required friction modifier additive which is compatible with all differentials... open, with a locker, or with a limited slip differential. It is hard to find a GL-5 gear lube that does not contain the additive.

Carrier breaks are always referred to as “numerically higher” or “numerically lower”.

Not necessarily and definitely not "always".

How often are you purchasing and installing carriers?

More than enough to know that they don't "always" say numerically higher or lower when describing carriers/gear ratios as you're claiming. Don't try to imply I don't know WTF I'm talking about.

Jerry definitely has gotten the California out of himself

Welcome to the south!!!!!

I’d love to see some examples of carriers or gears available for sale from vendors that don’t use numerically higher or lower to describe them. I truly have never seen it.

Try this again. As it didn’t go through earlier. 4.11 thick is for 3.73 and down meaning higher gear trac loc but my trac lok is wiped out I plan to go with a new one. The new one will be 3.92 and higher which is lower in gear ratio so the 4.11 Thick will not work right? Just trying to make sure I understand this?
Thanks

Thick gears are only for numerically lower carriers.

Thank you, now the next question since they make gear all the way to 5.13 that are thick should I get a carrier meant for 3.73 and down in case I don’t like the 411 gears?
Or is there a draw back for strength with the carrier?
