The Ford Racing M-6261-D351 roller camshaft bearings are engineered to significantly reduce friction in your Ford engine. These ultra-low-friction needle roller bearings are designed to operate with minimal lubrication requirements, allowing for the blocking off of stock cam oiling holes. With standard splash lubrication from the crankcase, these bearings receive adequate oil, which leads to decreased oil aeration and windage losses. For optimal performance, it is essential to use block machining and an SAE 8620 steel camshaft.
