The HRD-253-29D Flathead Piston Ring Set, number 45, is a vital component for Harley-Davidson enthusiasts who are restoring or maintaining their classic flathead engines. This comprehensive set includes all the necessary flathead piston rings required for a smooth and efficient engine operation.
The set includes 45 pieces of high-quality flathead piston rings, meticulously manufactured to fit perfectly into Harley-Davidson's flathead engine cylinders. Each ring is designed to withstand the rigors of high-compression combustion, ensuring optimal engine performance and longevity.
