RampCrab Brass Hex Wheel Hub Extensions +5mm for SCX24 & AX24 (Purple)

These +5mm hex wheel hub extensions from RampCrab add width to both sides of your 1/24 scale RC crawler, made from solid brass for extra weight and stability. Weighing 28 grams in total, they lower the center of gravity and improve handling on the trail. Compatible with Axial SCX24 and AX24 models, including Deadbolt, JLU, C10, Bronco, and more.

What fits this extension kit?

This kit works with 1/24 scale RC cars from Axial: AX24, SCX24 Deadbolt, Jeep JLU, C10, B-17 Betty, Gladiator, Bronco, and Power Wagon. Your wheel rims must have a center aperture larger than 3mm to fit over the hub. Check your model's manual if unsure.

What's in the box and how to install

The package includes four brass hex hubs, four purple aluminum nuts, four lock washers, and four screws. Installation is straightforward: remove the stock hex, slide on the new brass hub, and secure with the provided hardware. Do not overtighten the nut to avoid jamming the bearing. The wheels should spin freely without binding.

Why brass matters

Brass is denser than plastic, adding meaningful weight low on the chassis. The 28 grams of extra mass sit right at the wheel hub, which helps keep the tires planted on uneven terrain. This design also avoids the bulk of fake brake rotor weights, making it a cleaner upgrade for wheels with narrow openings.
