.308 Camshaft & Flywheel 3.308"Connecting Rod For Hemi Predator 212cc Kart

Overview

This is a high-performance, value-oriented racing upgrade package designed for builders seeking strong high-RPM power output with a cost-effective component setup for Hemi Predator engines.

Built around a .308 high-lift Hemi camshaft, it delivers aggressive valve timing, extended duration and improved airflow for maximum top-end performance. Supports a target operating range of 8200–8400 RPM, suitable for competitive kart racing and high-performance recreational builds.

Unlike premium billet racing configurations, this version uses a durable cast aluminum (die-cast) performance flywheel, providing a more affordable solution while still improving throttle response and engine acceleration over stock components.

✅ Fitment

• • Designed for 212cc Hemi Predator engines
• • Compatible with 196cc clone and GX200 platforms
