Frequently Asked Questions – ARC Billet Sidecovers
What does a billet sidecover do?
A billet sidecover replaces the stock cast engine side cover with a stronger, precision-machined component that supports the crankshaft
and improves bottom-end stability in high-performance small engine builds, including Predator 212 (Hemi & Non-Hemi), Predator Ghost,
Predator 224, GX200, GX390, Ducar, Tillotson, and Briggs platforms.
Why upgrade from a stock cast side cover?
Stock cast covers can flex under high RPM and heavy load. ARC billet sidecovers are built from 6061-T6 aluminum for improved rigidity,
better crankshaft alignment, and increased durability in competitive kart racing and demanding performance environments.
Which engines are ARC billet sidecovers compatible with?
ARC billet sidecovers are commonly used on Predator 212 (Hemi & Non-Hemi), Predator Ghost,
Predator 224, Honda GX160, GX200, GX390, 196cc Clone, Ducar, Tillotson engines,
and select Briggs & Stratton racing platforms. Always confirm exact fitment and engine configuration before ordering.
Do ARC billet sidecovers include bearings?
Many ARC billet sidecovers are designed for dual bearing support, but included components may vary by model.
Review the individual product listing to confirm whether bearings, seals, or installation hardware are included.
Will a billet sidecover increase horsepower?
A billet sidecover does not directly add horsepower. Its primary advantage is improving crankshaft stability and bottom-end strength,
which supports reliable high-RPM performance in racing applications.
Do I need special gaskets or hardware?
Using the correct gasket kit, seals, and hardware is recommended for proper fit and sealing.
ARC offers related components to help ensure a secure installation and long-term reliability.
