About This Product
Belt Drives Ltd. front pulley. 1 1/2 inch wide, 31 tooth, 11mm pitch. Fits 1955–1984 FL, FX, and FXR. Works with BDL kits 505845, 505835, 505830, and 505570. You need this for an 11mm primary belt drive on a Shovelhead or early Evolution motor. Check your existing pulley tooth count and belt width before ordering. The tooth profile keeps the belt tracking straight and spreads the load across the primary.
Manufacturer part number: 31SI.
