Combine all the needed components to finish your engine's oiling systemQuieter and smoother engine operationIncrease oil pressure, scavenge volume and engine oil flow25°-35° cooler engine temperatures15°-30° degree cooler oil temperatures15-30 lbs more psi of oil pressureEliminate wet sumping, blowby and oily air cleanersTest results show 3 horsepower gain and 4 ft./lb. of torque gain to the rear wheelBillet 7075 aluminum oil pump is 50% harder and stronger than the factory pump holds tighter tolerances under temperatureRace Series® full-travel hydraulic lifters have a full .200” of total travel designed with a slower bleed-down rate to handle very heavy valve spring pressures, increase engine rpm before valve float and have increased roller clearance for steep ramped camshaftsRace Series® short-travel hydraulic lifters have .115” of total travel and will increase rpm by decreasing valve float and valve-train harmonics while maintaining a quiet engineTravel reduction reduces the amount of oil that is required to fill the inside of the lifter which reduces oil aeration inside the lifter on steep, fast action high lift camshaft lobesIncludes bearing retainer plate and hardware.
