About this item

  • 20mm Wider Stance for More Stability: Add 20mm offset to each wheel side with these 12mm hex wheel hub extensions. The wider stance helps improve side-hill stability, cornering balance, and crawler control on rocks, trails, dirt, and uneven terrain—ideal for a more planted 1/10 RC crawler setup.
  • Helps Reduce Tire Rub & Improve Clearance: A practical upgrade and protect when larger tires, deep-offset wheels, or custom crawler bodies cause rubbing around links, shocks, fenders, or body panels. The 20mm extension gives extra wheel clearance while keeping the stance useful for trail driving and rock crawling.
  • CNC Aluminum, Lightweight & Durable: Made from CNC-machined aluminum alloy for better rigidity and wear resistance than many stock plastic hubs. Compared with heavy brass spacers, the aluminum design adds width without adding excessive rotating weight, making it a balanced upgrade for crawler and trail builds.
  • 12mm Hex Fit with Complete Hardware: Designed for many standard 12mm hex wheel setups with approx 5.5mm center holes and fits 4mm wheel axle bolts. Wheels with 4mm center bore require hole reaming for installation. Package includes 4 aluminum hub extensions, 4 M4 center nuts, and 4 steel pins for installation. Please confirm axle shaft size, pin size, and wheel center bore before ordering.
  • Fits Many 1/10 RC Crawlers, Check Before Buying: Compatible with many 1/10 RC crawlers using 12mm hex wheels, such as Axial SCX10 SCX10 II SCX10 III AX10 F350 D90 Wraith Redcat Gen7 / Gen8 Tamiya CC01 / CR01 90046 RC4WD and similar models. (Please check size before purchase, not suitable for trx4)

    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.
