New 1/4" brass oil lines pre bent with all necessary fittings. Fits Harley-Davidson Shovelheads 1966 - 1984. No hassle, fits like a glove. Not the wimpy 1/8" stuff! These lines will eliminate the problem of the "starving front head". On another note these will not change the flow or pressure due to the fact that this is metered in the rocker boxes but the lines will even it out between the front and rear. All compression fittings are pre-tightend, thread sealent is provided for the NPT-to-case and rockers. A stainless allen plug is provided for the rear rocker when installed is flush and unseen. Made in the USA! Under rocker split lines fit all carbs including S&S E but super B will require a 1" spacer between intake and carb otherwise enricher knob will hit the oil line unless you modify it. Most of our customers already have this spacer because it is also required for the air cleaner to clear fat bob tanks.
