CAM KIT RS 521 CD O/C M8

Not for '23-'24 models with 121" VVT motor. Short travel hydraulic lifters have 0.115" of total travel and will increase rpm by decreasing valve float and valve-train harmonics while maintaining a quiet engine Kit includes: Race Series® high volume oil pump, High Flow billet camplate, Reaper® Series camshaft, Race Series® short hydraulic roller lifters, one piece pushrods, Timken®/ Koyo® cam bearings, rocker arm studs/ nuts, gaskets, O-rings, ARP® cam/ crank fasteners, washers, moly paste and Loctite® 53% more scavenge gear volume over stock for M-Eight Twin-Cooled motors 27% more pressure and scavenge gear volume over stock for M-Eight Oil-Cooled motors 42% more scavenge volume with port sizing, matched passages and holes to the engine case for M-Eight Twin-Cooled motors and M-Eight Oil-Cooled motors 30% more pressure gear volume over stock for M-Eight Twin-Cooled motors Billet 7075 aluminum oil pump, which is 50% harder and stronger than the factory pump, holding tighter tolerances under temperature Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume Magnets in oil pump to help protect gears and pressure relief valve Reduces wet sumping, blowby and oily air cleaners Test results show 2 hp gain and 2 ft/lb of TQ gain to the rear wheel on M-Eight Increases oil pressure, scavenge volume and engine oil flow 15°-30° cooler oil temperatures for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors 10-30 more psi of oil pressure for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors 15°-25° cooler engine temperatures for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors 68% more oil volume to the crankshaft and connecting rod bearing for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors Made in the USA Feuling test results show a 50% reduction of engine sump oil level
