Carrier Bolt Type


9-Bolt	10-Bolt	12-Bolt
Generally speaking, the amount of bolts in the differential cover is the style rear

Carrier Types
Open	Posi (Clutch) (Limited Slip)	Posi (Cone) (Limited Slip)	Torsen (Torque Sensing)




OPEN - The ring gear spins the carrier, power is transmitted through 4 spider gears that mesh with each other, but only 1 axle transfers the power. POSI/Limited Slip (Clutch type) - The ring gear spins the carrier, a series of springs forces the 2 spider gears up against clutches that mate against the housing. Power is transmitted through the spider gears forced against the housing. There is constant spring pressure, so both wheels always spin at the same time, but the springs release tension when making a turn, allowing the clutches to slip which in turn allow one wheel to spin faster than the other. POSI/Limited Slip (Cone type) - The ring gear spins the carrier, a series of springs forces the 2 spider gears up against cones that create friction on the carrier housing. Power is transmitted through the cones forced against the housing. There is constant spring pressure, so both wheels always spin at the same time, but the springs release tension on the cones when making a turn, allowing the cones to slip which in turn allow one wheel to spin faster than the other. TORSEN - The ring gear spins the carrier, power is transmitted through a series of worm gears that "climb" on each other as torque increases. When the worm gears reach the spline gears, both axles are locked together through the worm gears.

Carrier Series

	Most 3-series gears have a small pinion tooth count, which makes the pinion small in diameter. Small diameter pinions require the ring gear to be closer to the pinion for the gears to mesh. In other words, if you install a 3-series gear on a 2-series carrier, the ring and pinion won't mesh.

2-series	2.59, 2.73; 3.08 on 7 3/4" rears or smaller
3-series	3.23, 3.42, 3.73 (also includes 3.08 on a 10-bolt 8.5" carrier)
