AXI312005 UTB18 Brass Hex

This product is a weighted wheel hex upgrade designed to improve stability, traction, and climbing performance for 1/18 scale rock crawlers. Machined from solid brass, each hex adds approximately 7g of low-mounted weight per corner, helping lower the center of gravity where it matters most for crawling performance. It is engineered specifically for the Axial UTB18 Capra platform, ensuring direct fitment as a replacement for the stock plastic hexes with included set screws. The added weight at the wheels improves side-hilling stability and reduces the chance of tipping on steep or uneven terrain. This set is ideal for performance tuning or replacing worn stock hexes for more consistent crawling control.

Features:

• Solid brass construction for maximum durability and added weight
• Adds approximately 7g per hex to lower center of gravity
• Improves traction and side-hill stability on technical terrain
• Direct replacement for stock UTB18 plastic hexes
