Dana 30 re-gear ???

Just got 1 question...I'm re-gearing my D30 to 4.56's ...I currently have 3.55's..my question is- When I get my new carrier for 3.73 and up..will I re-use my existing spider gears or will I need to get larger ones as well? Not sure if it matters but I'll be putting in a Lock right at the same time???? Thanks...

If you're putting in a Lock-Right, you don't need your spider gears anymore.

spiders and lockright will fit either carrier size so put in what you want but I'd put in the locker
