ARC 4.000 Inch Enduro Billet Rod for High-Stroke Kart Engine Builds

Stroker enthusiasts, take note: the ARC Billet Rod 4.000" Enduro opens up new realms of power in your Raptor Flathead setup. By extending stroke length, it increases engine capacity without major overhauls, delivering the torque surge needed to blast out of corners and hold leads.

This enduro variant prioritizes durability for stroked configurations, where stresses multiply. The 4.000-inch length pairs with longer pistons for volumetric efficiency gains, meaning more air and fuel burned per cycle for tangible speed improvements.

• Extended length for stroker applications, yielding up to 20% more low-end grunt.
• Reinforced big-end bearings to handle amplified forces in endurance races.
• Balanced weight distribution to maintain engine smoothness at elevated RPMs.

In competitive karting, where every horsepower counts, this rod turns potential into podiums. It resists the elongation that plagues lesser parts in high-displacement builds, ensuring your investment lasts through seasons of hard racing. Expect sharper acceleration and better top-end pull, all while keeping vibrations in check.

Integrating SKU: ARC6331 into your Briggs engine is a game-changer for mechanics seeking big results from targeted mods. It's not just about size—it's about smart engineering that amplifies performance without compromising the core's integrity. Race harder, recover faster, and outpace the field with confidence.

From dirt ovals to asphalt sprints, this rod's versatility shines, making it a favorite among tuners chasing that extra edge.
