Supertech Lash Caps 5.5mm Diameter 2.5mm Deep 1.73mm Thick for Racing Valves - LC-55-1.73P

Supertech LC-55-1.73P Lash Cap

The Supertech LC-55-1.73P Lash Cap is designed specifically for those who demand precision in their engine performance. Crafted with a diameter of 5.5mm, a depth of 2.5mm, and a thickness of 1.73mm, this lash cap effectively increases the diameter of slender valve tips. This feature is particularly beneficial for race engines utilizing narrower 6 or 7mm valves, as it allows for a larger footprint for the rocker arm's nose roller, ensuring smoother operation and improved reliability.

  • Durable Construction: Made from high-quality materials that withstand the rigors of racing.
  • Enhanced Performance: Provides a stable contact point for rocker arms, enhancing overall engine performance.
