Not sure what Spinlock meant by high speed carrier??? The new carrier is (slightly) bigger to accommodate the larger gears. Nothing to do with faster. They do look nearly identical but you will want a new carrier for sure.
Only necessary for 3.21s upfront.
Dana 30 front axle carriers have a break at 3.54 anything under 3.54 ie the 3.21 has a different carrier then anything above 3.54 You need to be careful as older wranglers had low pinion diffs and they are not the same as the new high pinion diffs that we have on our jks.
