About This Product
This replacement caliper piston is designed for the classic banana style calipers found on many early 80s Harleys. It is a direct replacement for OEM 44118-80 and is intended for use with a square O-ring. For front fitment, it works on late 1980 to 1984 FL models. For the rear, it fits late 1980 to 1984 FL, late 1980 to 1982 FX, and 1983 FXE models. If your brakes are sticking or showing signs of leakage, a fresh piston is often the cure. Sold individually, this high-quality piston ensures smooth operation and reliable stopping power for your vintage Big Twin's braking system, restoring the performance of your original equipment calipers.
Manufacturer part number: 507420.
