Designed for use with the unique combustion chamber of the Original Equipment or Factory CNC-Ported Heads for Twin- Cooled 103CI models, these pistons deliver impressive performance gains.

• The liquid-cooled exhaust valves reduce the chance of detonation, and allow the engine to take advantage of higher compression ratios
• Forged from high-strength aluminum, these 11.25 to 1 ratio pistons feature nickel-plated surfaces for enhanced durability, and special coated skirting for improved wear-resistance
• These pistons include Titanium SST rings to withstand the stresses seen in racing.
• Complete kit includes pistons, rings, wrist pins, and clips

Fits Harley-Davidson ’14-later FLHTCU, FLHTK and FLHTCUTG models with 103CI Twin-Cooled engines. All EFI models require ECM calibration* (priced separately). For race application only.
