RCLions Brass Wheel Hex Hub Adapter 8mm for Redcat GEN8 1/10 RC Crawler - 12mm Hex Size

The RCLions Brass Wheel Hex Hub Adapter (8mm thickness) is a direct-fit upgrade for 1/10 scale RC crawlers like the Redcat GEN8. It uses a 12mm hex size to attach wheels, adding weight to lower the center of gravity for improved stability on rough terrain. Made from durable brass, each adapter weighs approximately 0.634 ounces and measures just 2.36 x 1.1 x 0.28 inches.

What Does This Hex Hub Adapter Do for Your Crawler?

Adding weight to the wheel rims is a proven way to lower your rig's center of gravity. This brass adapter replaces the stock plastic hub to increase unsprung weight, helping tires grip better on rocks and slopes. The result is more predictable handling and reduced tipping during slow-speed crawling. Because it's brass, it resists corrosion and holds up to muddy, wet conditions without degrading.

Specifications at a Glance

Will This Fit My RC Car?

This adapter is designed for 1/10 scale RC crawlers that use a 12 mm hex drive system. It is a direct fit for the Redcat GEN8, a popular model in the crawling community. Other 1/10 crawlers with 12 mm hex wheels (such as many Axial or SCX10-style rigs) may also accept this adapter, but always verify your existing hex hub size before buying. The 8 mm thickness is a standard extension for adjusting track width or clearance.

How Much Weight Does It Add?

Each brass adapter weighs roughly 0.634 ounces. If you install a set of four, you add about 2.5 ounces of total weight to the wheel area. That extra mass sits at the wheel rim, effectively pulling the center of gravity downward. While the effect is subtle, many crawler drivers notice better sidehill stability and less body roll compared to stock plastic hubs.

According to customer feedback, these adapters have earned a 4.6 out of 5 star rating from 53 buyers. Common praises include precise fit, noticeable weight improvement, and quality brass construction.
