Briggs World Formula Valve Tappet Lifter for Precise Valve Timing

Valve train precision defines engine heartbeat in kart racing. The Valve Tappet Lifter (SKU 557098) embodies this by precisely following the cam lobe profile, translating rotational energy into linear valve lift without slippage.

• Hardened steel construction withstands 10,000+ hours of operation
• Minimizes lash adjustments, saving time during valve checks
• Enhances airflow for improved volumetric efficiency
• Compatible with flat-tappet cams in World Formula designs

Without a reliable lifter, valves can float at high speeds, robbing you of top-end power and risking damage. This component ensures every cycle is optimized, contributing to that elusive edge in close races. Track teams use it in overhauls to restore factory-fresh timing, often noticing sharper throttle pick-up immediately.

Its compact form fits seamlessly into cylinder head assemblies, and with proper lubrication, it quiets operation for focused driving. For those pushing engine limits, pairing with high-performance springs amplifies gains, turning your kart into a track predator.
