Supplier's note

1. Technical Breakthroughs:

   • 4340 Forged Steel: Outperforms standard 4130 steel with 30% higher tensile strength, enabling use in high-horsepower builds.
   • Weight-Optimized Design: Slots reduce rotational inertia by 20% compared to solid rods, improving throttle response.
   • Polished Bearings: Reduce friction by 15%, enhancing efficiency in high-temperature environments.

2. Version Selection Guidance:

   • Base Model: Ideal for OEM replacements or light-tuning applications (e.g., daily drivers).
   • Advanced Model: Suited for high-RPM street engines (e.g., forced induction builds) needing enhanced durability.
   • Pro Model: Designed for racing or extreme power adders (e.g., 500+ HP engines), with load capacity exceeding industry benchmarks by 30%.

With the Pro Model’s 195 ksi material strength, you can safely handle extreme engine loads without compromising reliability. Pair its lightweight design with nitrided surfaces to achieve a perfect balance of power and longevity.
