Mercury Rocker Arm inverts pushrod movement to create valve action to provide engines with vigorous breathing. Since 1938, Mercury had a vision of cars that would be comfortable, stylish, and good-looking. Showrooms also emphasized silent cabins, smooth rides, and handling, which allowed families to cruise without hassles. The badge has adapted the name of the winged messenger and it is a hint to speed and confidence whenever the key is turned. With each decade coming by, Mercury renewed interiors and suspension components to make trips on any road smooth. Drivers adored the appearance of Mercury vehicles such as Cougar or Grand Marquis which remained sleek but affordable. Mercury is a representation of both punch and practicality even after it ceased to be produced in 2011. The wailing silence of the highways and the spacious seats that made long distances seem to pass effortlessly are recalled by fans. Rocker Arm is mounted on top of the cylinder head and it rides on top of a shaft/stud with constant poise. The pivoted body is made of stamped steel or aluminum, and the needle bearings are made to cut through friction to achieve sharper response. Engine builders select ratios between 1.5-1.8 so that one Rocker Arm ratio doubles the lift of the cam into larger breath. Revs spanking will work against components but Rocker Arm forged or dynalite aluminum will remain firm and will help to keep the valve train straight. By a clean trade of pushrod thrust to valve travel, the Rocker Arm increases power with protection of fuel and emissions.
