Billet Aluminum Flywheel .308 Non Hemi Camshaft 3.308 Connecting Rod 70mm Flat Top Piston Performance Engine Upgrade Set for Predator 212cc Non Hemi

Overview

This is a high-RPM, modified-class performance package engineered for serious kart racers and engine builders seeking maximum airflow, increased compression, and extended RPM capability.

Built around a .308 high-lift racing camshaft, it delivers aggressive valve timing and extended duration for stronger mid-to-top-end power output. Designed for modified engines targeting up to 7000 RPM, this cam profile significantly increases engine breathing capacity when paired with upgraded valvetrain and bottom-end reinforcement components.

Core Component Breakdown

✅ Valvetrain & Ignition
To support high-RPM stability, the kit includes 26lb performance valve springs, providing stronger valve control and minimizing valve float under sustained load conditions. Ignition performance is optimized with an included F7TC high-performance spark plug, ensuring reliable combustion under increased compression and higher operating temperatures.

✅ Rotating Assembly
The rotating assembly is strengthened with a 3.308” heavy-duty connecting rod and bearing set, engineered to improve crankshaft stability and durability under racing stress. This ensures the engine can safely support the aggressive cam profile and elevated RPM range.

✅ Piston Kit
A GX220 70mm flat-top piston kit with rings and wrist pin is included to increase compression ratio and improve throttle response, delivering stronger torque and acceleration across the RPM range.

✅ Gaskets & Seals
For improved sealing and long-term reliability, this kit comes with a complete gasket and seal package, including non-hemi valve cover gasket, intake and exhaust gaskets, crankcase gasket, crankshaft oil seals, and a 70mm head gasket with locating tabs, ensuring full rebuild-level engine sealing integrity.

✅ Additional Performance Parts
Additional performance enhancements include a lightweight machined magnetic flywheel, designed to reduce rotational mass and improve throttle response, and a magnetic drain plug set (M10x1.25) to capture metal debris and extend engine life during high-performance operation.

✅ Fitment

• Designed for 212cc Non-Hemi Predator engines
