About this item

  • CNC Machined Solid Brass CNC precision-machined brass wheel hex adapters provide consistent fit and added weight, helping lower the center of gravity and improve crawling stability on uneven terrain.
  • Multiple Extension Options Available in 8mm, 10mm, 15mm, and 20mm thickness options to widen track width and adjust stance for different terrain and setup preferences.
  • Secure 12mm Hex Fit Standard 12mm hex design with M4 threaded interface ensures tight, wobble-free mounting. Note: The 8mm version installs directly without washers.
  • Designed primarily for TRX4 / TRX6 type 1/10 RC crawler axles using standard 12mm hex hubs. Fitment depends on axle stub length, pin diameter, and internal clearance. Not universally compatible with all 1/10 RC crawlers—please confirm measurements before purchase.
  • Package Contents & Installation Note Includes 4 wheel hex hub adapters and required hardware. Washers and spacers are included for thicker versions (10mm / 15mm / 20mm). Please verify axle and wheel clearance before installation.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.
