Overview
Yella Terra cup end adjusters are a quality replacement or service part for rocker assemblies using 3/8 UNF through-hole cup lash adjustment screws and 5/16 ball end push rods. This 16 piece set is the 29mm length version, supplied with matching stainless washers and 12 point locking nuts, making it suitable for a full V8 rocker set where this adjuster style and length is required.
Designed for accurate lash and preload adjustment, these adjusters use an internal hex for setting and a locking nut to secure the final position. The high strength construction and controlled heat treatment are intended to provide durability without unnecessary brittleness, an important detail in hard-working valvetrain components. They are a sensible choice when refreshing Yella Terra roller rockers, replacing worn adjusters, or setting up a performance classic Chrysler, Dodge, Plymouth or Valiant engine where the rocker and push rod combination matches these specifications.
Always confirm adjuster length, thread, oiling style and push rod end type before fitting. Longer adjusters should not be used as a shortcut to correct push rods that are too short.
