Ring and Pinion swap

[SPSERG]

Hello all, Its been a while since I have been online but I am back at it again... I am planning on purchasing a R&P kit (G2 from Quadratec) to regear my XJ. Its currently a factory Dana 44/Dana 30 with factory 3.55 gears. The kit I am looking at comes with install kit and required materials. What I am concerned about is carriers; these are factory units at 3.55 and I am seeing conflicting reports or needing new carriers to fit the new gears: 4.10. Can anyone confirm this? The kit makes no mention of needing new carriers. I have all winter to gather supplies since I am not going to attempt any work until the spring. Plenty of time to look over materials and videos before hand so I am prepared.

There is a carrier break on both axles and your 3.55's, You'll need new carriers.

They do make thick cut gears for Dana 44 to allow you to keep your existing carrier. I'd be inclined to just replace it, as open carriers are cheap-ish, but to each their own.
I am not aware of thick cut dana 30, so yeah...new carrier.

X2 100% on “D44 thick gears are a thing” and if you’re not going to do a full case locker, I don’t know why not to use the thick gears.

Another thing on thick cut gears - they are stronger than regular, and as you get lower and lower gearing (higher #) the ring gear actually gets smaller and smaller. Makes me think could be a weakness if you don't go with thick cut if available... just my 2 cents
