This Viton Rocker Shaft O‑Ring is a direct upgrade over the original EPDM material, offering improved durability and long‑lasting performance. Designed to withstand extreme engine heat and constant oil exposure, Viton provides a more reliable seal and reduces the risk of oil leaks around the rocker arm shafts.

Ideal for engines with aging or compromised factory seals, these O‑rings restore proper sealing integrity and help maintain cleaner, more efficient engine operation. Twenty‑four O‑rings are required per engine, and each one is backed by a 24‑month unlimited‑mileage warranty for added confidence.
