Lightweight 17mm Magnesium Metric Pattern Hubs 76mm Width for Spindles

Magnesium's magic shines in these 17mm metric pattern hubs, clocking in at just 76mm width for a featherlight touch on your kart's wheels. Forged from premium magnesium alloy, they slash unsprung weight dramatically—up to 50% lighter than aluminum rivals—unleashing quicker suspension reactions and nimbler steering that carves corners like a scalpel.

• Exclusively for 17mm spindles; adaptable to 5/8" with DSM58BRG bearing (separate).
• Factory-installed 8mm wheel studs meet industry standards for secure mounting.
• 76mm width supports compact wheel designs in metric chassis.

In weight-restricted classes like Mini Rok or cadet divisions, every gram counts, and these hubs deliver savings that translate to tangible speed gains. The metric pattern ensures compatibility with global tire brands, while the magnesium construction dissipates vibrations for a smoother ride, reducing driver fatigue over long motos. For trackside efficiency, pre-installed studs mean less assembly time, keeping your focus on strategy.

Engineers appreciate the hubs' rigidity despite low mass; they maintain shape under lateral forces, preserving camber and toe for optimal tire wear. Pair with lightweight rims to amplify benefits—your kart will feel alive, pivoting effortlessly through hairpins. In dusty or rainy conditions, the material's natural corrosion resistance keeps performance steady without added coatings.

Organize your metric inventory with these versatile pieces; they're stackable and durable for transport. As a bonus, the reduced inertia aids braking, shortening stopping distances for safer, more aggressive racing lines. From club days to nationals, these hubs organize your pursuit of excellence by prioritizing speed without sacrifice. Lug nuts sold separately to match your preferences.

Frequently Asked Questions

Q: Are these hubs compatible with 5/8" spindles?

A: Yes, while these hubs are designed for 17mm spindles, they can be adapted to 5/8" spindles by using the DSM58BRG bearing, which is sold separately.

Q: Why should I choose magnesium over aluminum hubs?

A: Magnesium hubs are significantly lighter—up to 50% lighter than aluminum—which reduces unsprung weight. This allows for quicker suspension reaction, improved steering response, and better vibration dissipation, which helps reduce driver fatigue.

Q: Do these hubs come with lug nuts?

A: No, the hubs come with factory-installed 8mm wheel studs for secure mounting, but lug nuts are sold separately so you can choose the style and type that best fits your setup.

Q: Are these suitable for weight-restricted karting classes?

A: Absolutely. In classes like Mini Rok or cadet divisions where every gram matters, the weight savings provided by these magnesium hubs can translate into tangible speed gains on the track.

Q: How do these hubs affect my kart's handling?

A: The reduced mass and high rigidity of these hubs help the kart pivot more effortlessly through corners. By maintaining their shape under lateral forces, they help preserve your alignment settings (camber and toe) for more consistent tire wear and handling.
