This comprehensive kit combines all the necessary components to upgrade your engine's oiling system under one part number, delivering measurable improvements in oil pressure, volume, flow, and scavenging.

Performance Benefits:

• 30% more pressure gear volume over stock
• 53% more scavenge gear volume over stock
• 68% more oil volume to the crankshaft and connecting rod bearings
• 42% more scavenge volume through optimized port sizing and matched passages
• 15-25 degree cooler engine temperatures
• 15-30 degree cooler oil temperatures
• 10-30 PSI increase in oil pressure
• Reduces wet sumping, blow-by, and oily air cleaners
• Test results show 2 HP gain and 2 ft-lbs of torque gain to the rear wheel
• Quieter and smoother engine operation

Kit Includes:

• Race Series billet 7075 hard anodized aluminum oil pump - 50% harder and stronger than factory pump, holding tighter tolerances under temperature
• High Flow billet camplate made from 7075 aluminum - 50% harder and stronger than factory camplates
• Race Series hydraulic roller lifters with full .200" total travel
• Cam installation kit with cam bearing
• Cam and crank bolts and washers
