Gears are sold as a matched set. They come with a ring gear and a pinion gear that are factory matched as a pair.

I think you mean you don't want to change the carrier, in which case, you should be okay using the same carrier up to 4.56:1 gears. I believe 3.73 is the cutoff, where anything higher (lower ratio gears, such as 3.31) would require a different carrier.

edit: The carrier break above is only for Dana 30 front differential. For the Dana 44 rear that you likely have in your CJ, 3:73 is the lowest gearset for that carrier. Anything lower (higher numerical ratio) will require a new carrier.


edit 2: The D44 axle has many gear ratios available, from 3.07 to 5.89. The closest to 4.00 that you are looking for are either 3.92 or 4.11.

It can vary by region but to have a competent shop do it I'd say $200-$300 per axle for gears and install kits and the same again for labour is a pretty safe number. If it were me I'd plan to spend $1000 just for the re-gear. Add onto that what the lockers you want will cost.

Shop time around here is $80-$100 /hr. A good guesstimate is ~4-6hrs shop time plus materials per axle. A decent gearset is ~$200 ea, plus $200 ea in new bearings, seals, etc. The locker/limited slip are ~$600 ea.

So, all totaled, you're looking at ~$2000 in parts and another ~$1000 in labor.

edit: As stated above, shop rates can vary widely by region. Shop around to get a feel for pricing in your area.
