Genuine BMW i3s Rocker Shaft Spring Kit

The BMW i3s Rocker Shaft Spring Kit provides the range extender power unit with rock solid valve controls that keep it smooth, punchy and protected. Designed for every production year of the spirited BMW i3s, the Rocker Shaft Spring Kit maintains 70 to 90 pound seat pressure and over 200 pound open force in order to keep intake and exhaust valves sealed despite high rpm. Early i3s editions utilizing classic pushrods and later i3s versions utilizing quick reacting overhead cams both bolt the Rocker Shaft Spring Kit in place to ensure identical reliability across the family. Because the Rocker Shaft Spring Kit on its own automatically takes up clearance as parts wear out, drivers avoid the misfire, valve float and the nightmare of piston contact, all while the compact range extender engine retains its lively character. The component also keeps combustion chambers tightly sealed, a feature that helps the lightweight BMW i3s sprint harder while not depleting battery reserves. Unlike heavier systems in larger cars, the Rocker Shaft Spring Kit adds almost no mass, allowing the carbon fiber passenger cell, aluminum chassis and wider sport wheels to work together to provide maximum handling and safety. Consistent valve timing gives lower vibration at speed, allowing the stability electronics to work with greater precision with a subtle but important safety gain, recognized by the long term owners of the BMW i3s. Installing the Rocker Shaft Spring Kit requires no special tuning and fits seamlessly on every BMW range extender cylinder head, both original pushrod layout and modern follower head designs. This plug and play nature has led the Rocker Shaft Spring Kit to claim its own in BMW circles as a durable part that packs a massive impact on efficiency, longevity and driver confidence.
