High-Performance Upgrade Kit for Predator 212cc Non-Hemi Engine
Aluminum Flywheel + 70mm Flat-Top Piston + 3.308" Billet Rod – Complete Racing Bundle
⚡ Unlock Higher RPMs & Horsepower | Precision CNC-Machined | Bolt-On Installation
KEY FEATURES
✔
Aerospace-Grade Aluminum Flywheel – 30% lighter than stock cast iron,
CNC-balanced for smooth operation at 8,000+ RPM (safe for racing
applications). Reduces rotational mass for quicker throttle response.
✔
70mm High-Compression Flat-Top Piston – Thin-ring design minimizes
friction, while the lightweight wrist pin reduces reciprocating mass.
Paired with the included 0.010" head gasket, boosts compression to
~10.5:1 (vs. stock 8.5:1) for stronger low-end torque.
✔
3.308" Forged Billet Connecting Rod – Made from heat-treated 4140
chromoly steel, handles 2x the load of OEM rods. Ideal for nitrous,
turbo, or high-RPM builds.
✔
Complete Ready-to-Run Kit – Includes everything for a full upgrade: HD
ignition coil, 18lb valve springs (prevents float), and full gasket set.
No extra parts needed!
