About This Product
This front caliper piston assembly from MCS is engineered for 1974 to 1977 XL Sportster and FX models, excluding FXS Low Rider models. It is a vital component for maintaining the hydraulic integrity of your front braking system. Over time, original pistons can develop wear or corrosion that leads to brake drag or fluid leaks. This assembly provides a reliable solution, replacing OEM 44275-74 and 507410 to restore the responsive braking performance your Ironhead or Shovelhead needs. For any mechanic working on mid-seventies Harleys, this piston assembly is a key part of a thorough brake system overhaul, ensuring your bike stops as well as it goes.
Manufacturer part number: 507410.
