Auburn Gear Select-A-Loc Differentials

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack 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 highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

MSD Pro-Billet Front Drive Distributors

MSD's Pro-Billet front drive distributors are the solution for race engines that don't have room for a standard distributor, due to firewall clearance or intake combinations. They're run by a wide 9mm belt that is driven by a pulley installed on the camshaft. The belt is wider than any other drive assembly for increased strength and durability. The distributor head is CNC-machined from billet aluminum and is secured to a stout billet aluminum bracket for strength. This system is an extremely accurate way to distribute the spark energy in harsh racing conditions. The distributors have a built-in belt adjustment feature for easy tension adjustments, and a band clamp mount for easy rotor phasing adjustments. They include MSD's Pro-Cap that is injection-molded from Dupont Rynite material for high dielectric strength, and the five in. diameter ensures accurate spark delivery. The distributors are supplied with mounting bolts, a cam pulley, hardware, and a drive belt. They must be used with a Jesel camshaft belt drive kit and an MSD Flying Magnet crank trigger.
