High-Precision Ball Bearing for Raptor Crankshaft Support

Precision engineering starts at the heart of your engine: the Ball Bearing, SKU 555149. For Briggs Raptor flathead setups, this bearing facilitates effortless crankshaft movement, slashing internal resistance that saps power.

Superseded by 99157, it features sealed construction to block contaminants, ensuring longevity even in dusty track conditions. The impact on performance is profound—smoother operation means higher sustainable RPMs, quicker rev-matching, and ultimately, faster lap times. Pit crews love how it organizes bearing maintenance, with easy access points for inspections.

• High-load capacity for demanding races
• Low-friction balls for minimal energy loss
• Compatible with standard Raptor housings
• Reduces noise and vibration for driver comfort

Envision your kart gliding through corners with less mechanical drag; this bearing makes it reality by optimizing rotational dynamics. It's not just a part—it's the foundation for a speed-focused engine that keeps you ahead of the pack. Racers report fewer overhauls, allowing more track time and better organization of spare inventories.

In the world of karting, where margins are thin, this upgrade ensures your power delivery is as efficient as possible, propelling you toward victory.
