*Note - GM 12 Bolt Cars came with a carrier break at 2.76, and 3.73. If your vehicle came stock with a 3.42, and you want to run a 4.10 or numerically higher ratio, you can use a THICK gear and keep your stock differential. Example: going from 3.42 to 4.56, use a 12BC456T THICK gear set and you won't have to purchase a new carrier.

- All Motive Gear master bearing kits include: front and rear pinion bearing, pinion seal, pinion nut, pinion shims, carrier bearings, carrier shims, pilot bearing (where applicable), crush sleeve, ring gear bolts, gear marking compound, brush, thread locking compound, and cover gasket or RTV.
