RampCrab Brass Hex Wheel Hub Extensions +5mm for SCX24 AX24 RC Crawler – Red

Add 5mm of track width per side to your 1/24 RC crawler with these brass hex hub extensions from RampCrab. Made from solid brass, the set weighs 28g and includes four hex hubs, four red aluminum nuts, four lock washers, and four screws. Designed for SCX24 and AX24 models, these extensions help improve stability and prevent wheel binding with certain wheel combinations.

What problems do these brass hex hubs solve?

Many SCX24 owners run into issues when fitting aftermarket wheels. Some wheels have a center aperture too small for larger brass fake brake rotor weights, or the stock hex hubs don't provide enough clearance. These +5mm extensions solve both problems by lengthening the hex hub and widening the stance. The added brass weight (28g total) sits low, helping lower the center of gravity for better crawling stability.

Technical specifications at a glance

Which RC models are compatible?

These hubs fit 1/24 scale Axial AX24 and SCX24 chassis including the Deadbolt, Jeep JLU, C10, B-17 Betty, Gladiator, Bronco, and Power Wagon. They also work with any wheel rim that has a center aperture larger than 3mm. Always check your model's manual or measure your wheel bore before buying.

What's included and how to install?

You get four brass hex hubs, four red anodized aluminum nuts, four lock washers, and four screws. Installation is straightforward: remove the stock wheel nut, slide the stock hex off, place the new extended hex on the axle, then mount the wheel and secure it with the included nut and washer. Do not overtighten the nut as it can bind the bearing. Once installed, the wheels should spin freely without binding.

Frequently asked questions about SCX24 wheel spacers

Will these fit my stock SCX24 wheels?

Yes, as long as the wheel's center hole is larger than 3mm. Most stock wheels have a sufficient opening.

Do I need to lengthen the axle shafts?

No. The +5mm extension is within the range the stock axle shafts can handle without modification.

What's the advantage over brass fake brake rotors?

These hubs are slimmer and work with wheels that cannot accommodate the larger inner diameter of fake brake rotor weights. They also provide a wider track for better stability.

Are color variations possible?

The hex hubs themselves are raw brass. The included nuts are red anodized aluminum. Note that actual colors may look slightly different on screen.
