• High-quality 10mm valve adjusting screws for Type 4 engines

• Perfect fit for 1800cc-2000cc Type 4 & 2100cc, 1900cc Waterboxer engines, not 1.7cc engines

• Heat-treated for long life and consistent valve adjustments

These 10mm valve adjusting screws are designed for 1800cc-2000cc Type 4 engines 85-92 and 2100cc & 1900cc Waterboxer engines 89-92 from Chassis 24-K-025 780. Unlike cheap, poorly made alternatives, these screws are heat-treated for durability and long-lasting performance, ensuring smooth and consistent valve adjustments over time.

Old valve adjusting screws often seize in the rocker arm, requiring removal with a torch and vice grips. However, this method necessitates replacement. Regularly adjusting with new, high-quality screws prevents this issue and ensures easy movement. Worn tips on old adjusters can make valve adjustments difficult, but these new adjusters provide a smooth, hassle-free solution.
