This LG Motorsports designed system was developed along side our World Challenge Corvette Race cars to meet the demands of racing while allowing you the trouble free worries for your street car. This system uses a special pinion nut with a drive plate and custom billet aluminum cover. This billet cover allows the special 2 stage mechanical pump to be mounted to the rear end. The mechanical driven, two stage pump not only pulls the fluid from the differential and transmission but also pumps the fluid through 2 separate coolers to increase the life of your Corvette drivetrain. No worries of electrical wires, shorts, or failures. Every time the car rolls it is pumping fluid!
