ARC Racing: Billet Power for Karts and Minibikes

I've installed more ARC Racing parts than I can count over the years in the shop. These guys make billet components that take small-engine racing seriously – think go-karts, minibikes, and junior dragsters powered by Predator, Clone, or Briggs mills. No flimsy castings here; everything's CNC-machined from solid billet for strength and precision.

Their flywheels stand out. Stock ones warp under heat and spin, throwing your ignition timing off mid-race. ARC's billet flywheels stay true at 8,000 RPM and beyond, with keyways that lock in tight. Pair one with a heavy flywheel for low-end grunt or a lightweight version for quick revs – your call based on the track.

Rods, Cranks, and Valve Train Essentials

ARC rods are beefy H-beam designs that shrug off high compression builds. We've seen them survive 14:1 setups without bending. Cranks come balanced and nitrided, ready to spin smooth in stroked motors. And don't sleep on the valve train: roller rockers, retainers, and springs that let you rev harder without float.

• Billet flywheels for Predator 212 and Clone HX270
• I-beam and H-beam connecting rods
• Stroked cranks for more displacement
• Valve springs and titanium retainers
• Full kits for Briggs Animal and World Formula

These parts aren't just for track days. Minibike guys love them for backyard bombs, and junior dragster teams rely on ARC for consistent ETs. Installation's straightforward if you torque to spec – always use ARP studs where possible.

Quality shows in the details: black anodizing that doesn't chip, laser-etched logos, and tolerances tighter than OEM. Prices beat custom fab shops, and they last seasons, not races. If your engine's maxed out stock, ARC is the next step. Browse the lineup, match to your setup, and get back to winning.
