LIMITED SLIP DIFFERENTIAL TO FULL-LOCK… AN AUBURN GEAR EXCLUSIVE.
This Select-A-Loc® model locks the axle shafts to the diff housing to transfer torque directly from the case, not through the gears.
This electronically-actuated differential operates as a limited slip differential until placed in full-lock mode. Select-A-Loc’s exclusive design promises exceptional traction for power sport enthusiasts and anyone driving in extreme conditions.
Select-A-Loc® offers many advantages over OEM differentials and other specialty differential brands:
Gearing is made from heat-treated hardened steel…tough, durable, and reliable in the most extreme conditions
Heavy-duty construction and high-strength case material allow safe instant engagement while under full load (at low speed, below 5 mph).
Can be used in front axle applications, with or without lockout hubs.
Lightning fast engagement and disengagement.
Select-A-Loc® is virtually silent when used with recommended lubricants.
Easy installation, no air compressor or hoses required; saves space and has less moving parts.
Backed with a 1 Year Warranty PLUS an Additional one-year warranty when used with Auburn Gear Differential Oil (see below).
IMPORTANT NOTE: Select-A-Loc® is NOT recommended for use with front axles that feature an “inter-axle disconnect.”
How it Works… Select-A-Loc® Limited Slip to Lock
Select-A-Loc® is a selectable traction device featuring an ON/OFF switch mounted near the driver.
When OFF, the clutch pack (7), located behind the side gear (6), activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the high traction wheel.
When the switch is turned ON to activate the locking mode, current is sent to the electromagnetic coil (8). The coil is retained by a clip that fits over one of the bearing cap bolts, making it non-rotational.
The coil rides on a ball bearing (9), and the ball bearings spin with the differential case (10). The coil creates a magnetic flux so that the pilot cone (1) is pulled into engagement with the differential case (10). This frictional engagement causes the bearing balls (2) to ride up on a ramp machined into the side gear (3). This radial travel of the balls (2) also causes lateral movement of the side gear (3).
The side gear lateral movement (3) applies a force onto the center block (4). The center block has an elongated hole that the center pin (5) fits through, allowing it to float. The center block also applies force to the opposite side gear (6) to compress the clutch pack (7) and provides the vehicle with a solid axle assembly that transfers 100% of the torque to both wheels, delivering maximum traction. NOTE: The side gear (3) is not included in the Master Install Kit. However, the pinion gears (*) are included.
Electronic Activation
The Select-A-Loc® easily activates the locker mode by simply turning on the switch mounted inside the vehicle cab. When turned off, the differential works as a regular limited slip differential, responding automatically when torque is applied.
Street-Worthy!
Select-A-Loc® is very much built for the street, providing smooth, quiet operation. In fact, Auburn Gear differentials were used as original equipment in the first muscle cars. Plus, they are aggressive enough to be used in other performance applications. However, when the Select-A-Loc® is in full-locker mode, you may experience some under or push steering.
