Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Machined brass 9mm hex adapters for crawling upgrades
These 9mm brass wheel hex adapters are CNC style machined for TRAXXAS TRX4 Trail Crawler applications to increase lateral track and rotational inertia, improving low speed traction and vehicle stability. Each adapter measures 9mm thick, approximately 4mm thicker than the original hex, with an individual mass of about 6g as supplied.
The increased hex thickness reduces the lateral wheel to hub gap on TRX4 hubs and provides an outboard offset without changing suspension geometry. The component set is supplied with the required hardware for direct replacement of stock hexes where the TRX4 wheel hubs accept 9mm hex thickness.
Standard installation involves wheel removal, replacement of factory hex with the brass adapter, and refitting with the supplied fasteners while confirming clearance and seating. Periodic inspection of fasteners and wear points is recommended for sustained upgrade performance.
Packing includes
- Hex Adapter – 4pcs
- Stainless Steel Screw Shaft M4x2.5×11.8 – 4pcs
- Shims 5mm – 4pcs
- 5mm Metal Washer – 4pcs
- Stainless Steel Hex Socket Screw 10mm – 4pcs
Original Name / Part No:

This item is compatible with

- TRAXXAS TRX4 Tactical Unit
- TRAXXAS TRX4 FORD Bronco
- TRAXXAS-1/10 TRX-4 BLAZER 82076-4
What are the exact dimensions and mass per adapter?
Adapters are 9mm thick brass units, around 4mm thicker than the original hex. Each adapter mass is approximately 6g as supplied, offering measurable rotational inertia for crawling control.
How do these integrate with TRX4 hubs?
They replace standard hexes where the TRX4 wheel hub accepts a 9mm hex thickness and use the supplied fasteners for direct mounting. Confirm hub compatibility prior to fitting.
What inspection is recommended after fitting?
Check torque on the supplied fasteners after initial runs, inspect for wear or loosening at intervals, and verify steering and suspension clearance following installation. Write Product Review Please sign in your account before you can write any review.
