Old-Stf Stainless case-to-rocker box oil lines for Harley-Davidson Big Twin 1966-1984

These stainless oil lines are functional and beautiful! The split design routes oil to both rocker boxes immediately from startup, not sequentially from rear to front as the factory lines do, saving wear and tear on the rocker boxes and components within. The black fittings and stainless lines provide a unique contrasting look, too, whether your engine is natural finish or black. Kit includes a stainless plug that fits flush when installed that blocks the unused rear rocker inlet. Made in USA.
