Whether you are rebuilding your entire rear assembly or just swapping out worn mounting hardware, this hub guarantees a bulletproof fitment.\u003c\/p\u003e\u003ch2\u003eSeamless Integration with Your Setup\u003c\/h2\u003e\u003cp\u003eTuning a kart requires a holistic approach—from optimizing your engine parts to refining your turn-in response with a go kart steering wheel upgrade. This Righetti Ridolfi hub complements those modifications by anchoring the rear end, allowing your chassis to track true through high-speed sweepers. It features the standard European bolt pattern (3\/58) and comes pre-fitted with heavy-duty M8 steel wheel studs, making wheel changes in the hot pits fast and secure. If you are already running a precision go kart steering kit, adding this 115mm rear hub will balance the chassis dynamics, giving you the confidence to attack apexes without fear of the rear stepping out unpredictably.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications \u0026amp; Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended 115mm Profile:\u003c\/strong\u003e Maximizes rear grip and chassis stiffness, ideal for shifter karts and high-horsepower classes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e40mm Axle Compatibility:\u003c\/strong\u003e Precision-machined bore fits seamlessly onto standard 40mm European and modern 206-specific axles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBillet Aluminum Construction:\u003c\/strong\u003e Offers an exceptional strength-to-weight ratio, reducing unsprung mass without sacrificing durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack Anodized Finish:\u003c\/strong\u003e Provides superior corrosion resistance and a sleek, professional aesthetic in the paddock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated M8 Steel Studs:\u003c\/strong\u003e Factory-installed wheel studs ensure secure wheel mounting and strip-resistant longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Euro Pattern:\u003c\/strong\u003e Utilizes the universal 3\/58 bolt pattern for broad compatibility with modern kart wheels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8mm Keyway:\u003c\/strong\u003e Locks securely into the axle keyway to prevent rotational slipping under heavy acceleration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why should I choose a 115mm hub over a standard length hub?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The 115mm length provides a wider clamping surface on the axle, which increases chassis stiffness and rear-end grip.
