GPM Racing Aluminium with Brass Lid & 9mm Hex Adapter RC Axle Weight Set - GPM-TRX4023B

The GPM Racing TRX4023B Aluminum Axle Weight Set with Brass Lid and 9mm Hex Adapter is a 16-piece portal axle weighting kit designed for the Traxxas TRX-4 crawler. GPM Racing produces this set specifically to add concentrated weight low and outboard at the axle ends of the TRX-4, improving traction and stability on technical crawling terrain. The aluminium body combined with a brass lid gives each weight a dual-material construction that maximises mass while keeping the parts compact, and the included 9mm hex adapters integrate the weights directly into the wheel hub assembly.

Key Features

• Dual-material design uses aluminium housings paired with brass lids to concentrate weight effectively at the portal axle ends
• Brass lid adds significant mass in a small footprint, making it a purposeful choice for low-centre-of-gravity crawling setups
• 9mm hex adapters are included, allowing direct fitment to the TRX-4 portal axle hubs without separate hardware purchases
