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.
