Two Piece Carrier

Back to article View Gallery

Inside of the differential sits a massive two-piece carrier, which uses the ring gear bolts to merge the two halves. On this particular unit, a Grizzly Locker sits in place of the factory spider gears. If you plan to re-gear your 14-bolt with a numerically higher ratio such as 5.38:1, most aftermarket gearsets will require a 4.10 and down differential carrier. The case break on the 14-bolt is 4.11 and down and 4.56 and up.
