  • The ECTED Max is a selectable traction device; an on/off switch is mounted near the driver. When off–the clutch pack,located behind the side gear provides the limited slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed and thereby providing bias torque to the high traction wheel–your performance limited slip differential action. When selected on, current is sent to the electromagnetic coil. 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. The ball bearings spin with the differential case. The coil creates a magnetic flux so that the pilot cone is pulled into engagement with the differential case. This frictional engagement causes the bearing balls to ride up on a ramp machined into the side gear. This radial travel of the balls also causes lateral movement of the side gear. This applies a force onto the center block. The center block has an elongated hole that the center pin fits through, allowing it to float. The center block applies force to the opposite side gear, compressing the clutch pack giving the user a solid axle assembly–the spool/locker performance you desire at the strip/off-road. ECTED Max gearing is made from aircraft quality, 9310 heat-treated billet steel. Tough as nails! ECTED Max can be switched on or off on the fly, at any road speed. ECTED Max does not have any shift forks or pins that must be lined up to obtain locker mode. ECTED Max is quiet. Good-bye to noisy lockers! ECTED Max is backed by industry-leading 1 year warranty, like all Auburn Gear Performance Differentials. ECTED Max is backed by the industry-exclusive program. D-REX=Differential–Replacement EXchange Program. ECTED Max can be used in front axle applications–with or w/out lockout hubs. ECTED Max is the only selectable locker offering both limited slip and locker modes. Forget the rest-go with the best!
