I am getting ready to replace my stock gears with 4.30's. Is there anything other than the gears, and rebuild kit that I need? Does the carrier need replacing?

Depending on your cars mileage, the usual items that require replacement are:

Pinion Bearing (may not be needed, but for ~ $20.00 it's a good idea to replace it while the rear is apart)
Pinion Seal
Pinion Nut
Crush Sleeve
Shims

Some type of speedometer correction device will be required - either a SpeedCal (~ $90.00 - $100.00) or a custom chip (~ $275+). Your speedometer will be off considerably otherwise.

All of those items usually come with the kit, though, correct?
The SpeedCal definately doesn't - I'm not sure about all of the other items.
