Frequently Asked Questions – ARC Billet Connecting Rods

What is the advantage of a billet connecting rod?

A billet connecting rod is precision-machined from high-strength aluminum rather than cast. This provides superior durability, improved crankshaft stability, and better resistance to rod stretch under sustained high-RPM racing conditions in performance engines.

Are ARC billet rods stronger than stock OEM rods?

Yes. ARC billet connecting rods are significantly stronger than cast OEM rods and are engineered for high-performance small engine builds where elevated RPM, increased compression, and aggressive racing conditions can cause factory rods to fail.

Which engines are ARC billet connecting rods compatible with?

ARC billet rods are available for Predator 212 (Hemi & Non-Hemi), Predator Ghost, Predator 224 (Non-Hemi), Honda GX160, GX200, GX390, 196cc Clone engines, Ducar, Tillotson, and select Briggs & Stratton racing platforms. Always confirm journal size, rod length, and piston compatibility before ordering.

Do ARC billet rods require special installation?

Proper installation requires accurate torque specifications, correct bearing clearance, and careful measurement of crank journal dimensions. Mechanical experience is recommended for safe and reliable installation in high-performance engine builds.

Will upgrading to a billet rod increase horsepower?

A billet connecting rod does not directly increase horsepower. Its primary benefit is improving bottom-end strength and reliability, allowing your engine to safely operate at higher RPM and support additional performance modifications.

Are ARC rods suitable for competitive kart racing?

Yes. ARC billet connecting rods are widely used in competitive kart racing, Predator Ghost racing, Ducar and Tillotson performance builds, drag racing, and high-performance minibike applications where durability and high-RPM reliability are critical.
