The V-Twin 51-1003 FL Swingarm Frame is designed for 1958-1964 Harley-Davidson FL applications. This frame accepts Panhead or Shovelhead engines, a 4-speed left-side-drive transmission, a seat post, and round or square swingarms. It features a lower-drop frame design with provisions for a 6-volt battery and an early wraparound oil tank.
Forged components include the neck, motor mounts, front transmission mount, top seat post yoke, fender strut, swingarm pivot mount, and footboard mount. The neck accepts a plunger-type lock assembly and includes provision for a lock insert. The frame accepts round 1958-1972 drum-brake swingarms or square 1973-1985 swingarms. Rear drum-brake models use 13-1/2-inch shocks, while rear disc-brake models use 12-inch shocks. The seat post bushing may require further reaming for proper fit.
Neck key lock and shock studs are ordered separately. Suggested components include the V-Twin #37-9021 Neck Key Lock and #54-0464 Shock Studs. The replica frame has no serial numbers stamped on it; V-Twin supplies a Bill of Sale. UPS may classify this part as oversized for shipment compared with its actual weight, which may result in higher shipping costs.
