    I've looked through some past threads regarding thick & thin gearsets and the ability to use a thicker gear in a 14 bolt high gear carrier instead of replacing the entire carrier.

    I am working with 3.73 gears in a D44 front and 14FF rear. If I understand correctly I can get a thick 4.56 gear for the 14FF to avoid replacing the carrier.

    Does this also apply to the D44 thus saving me from buying a new 44 carrier?

    To my knowledge they only make thick gears for the 14FF.

    They make thick gears for just about every differential there is. That is exactly what they are for, go ahead and get them.

    Thick cut gears have become very common in the last 5yrs or so. You used to have to swap carriers most times but now unless you are buying a locker their is really no need to change carriers in most cases. I run thick gears in my rear axle and have had no issues at all. It is a lot nicer design then the .100 spacers that proceded them.

    Not to hijack, but this goes along with the question. I have a D44 with an ARB running 3.73's. I have been told in the past I cannot go to a higher numerically gear do to the carrier being a 3.73 and down.

    Would the Thick gears work with an ARB carrier?

    Yes, that is what they are designed to do exactly.

    An FYI for anyone interested, they do not make thick gears for a GM D60F standard rotation. The carrier will have to be changed out, or replaced with something like a detroit that replaces the carrier as well.

    You posative on this? I thought a standard rotation front 60 like GMs uses the same gears as a rear D60. I have 5.38 thick cut gears in my Ford rear 60 that is under my TJ. I would think those same gears can be used in a front GM D60. They are Yukon Gears if that helps.
