Description

Billet Aluminum Retainer Kit – Briggs 21–23HP Vanguard V-Twin (Model 38)


Unlock more RPMs and boost your engine’s durability with EC’s Billet Aluminum Valve Retainer Kit for Briggs & Stratton 21–23HP Vanguard V-Twin (Model 38) engines. Designed for performance and reliability, these lightweight billet retainers reduce valve train mass, improving high-RPM stability and engine response—without sacrificing durability.


Performance You Can Feel:

  • Lightweight Design for RPM Gains
    Every gram matters at high speed. Reducing valve train weight allows the engine to spin faster—each gram removed on the valve side is worth up to 40 RPM. Our billet aluminum retainers give you the edge for more aggressive cam timing and improved throttle response.
  • CNC-Machined Billet Aluminum
    Precision-machined in the USA for tight tolerances and consistent quality. These retainers are a direct upgrade over stock stamped retainers, offering better durability and performance in demanding applications.
  • Hard Anodized for Strength & Style
    Finished in our signature factory red hard anodizing, these retainers not only resist wear and fatigue, they also look great in any performance build.
  • Stock Spring Compatibility
    Designed to work with OEM valve springs, making them the perfect bolt-on upgrade for mild builds or engines running stock springs with upgraded cams or rockers.


Kit Includes:

  • (Set) Billet Aluminum Valve Retainers with locks
  • Compatible with Briggs Vanguard V-Twin 21HP - 23HP (Model 38)
