About This Product
Restoring a classic 45" Sidevalve or Servi-Car requires high-quality internal components to keep that vintage iron running smoothly. These Samwel Supplies pistons are designed for the iconic 45 cubic inch Flathead engine and come in a +.07" oversize to accommodate bored cylinders. This kit is sold as a set of two and includes premium Hastings rings, which are known for their excellent oil control and durability in air-cooled engines. Replacing OEM number 22259-29B, these pistons are manufactured to precise tolerances to ensure proper compression and thermal expansion characteristics. Whether you are reviving a military WLA or a hard-working Servi-Car, these pistons provide the reliability needed for the next generation of riding. They are a must-have for any serious engine builder looking to maintain the legacy of Harley-Davidson’s sidevalve history.
