S&S, die-cast rocker cover kit. Chrome

84-99 Evo B.T. (NU). For head or bottom crank vent

Chrome. Die-cast aluminum. Rocker covers to be used with all S&S Evo type, stock H-D Evo B.T. and 86-03 XL engines. S&S rocker cover kits come complete with gasket set and OEM style umbrella valves (special breather flap with S&S Evo die-cast covers) to accomodate most aftermarket & stock Evo engines, both bottom (84-92) as head vent (93-99) models. Note: Billet rocker covers are approximately 1/2" (12mm) lower than die-cast rocker covers. All earlier S&S 79" and 100" S&S Retro-Fit Evo engines, made to fit Shovelhead frames, are equipped with billet covers for this reason. If required, see 512353 for the lower billet version.
