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
Precision hex adapter 23mm for TRX4
These 23mm aluminium hex adapters are supplied for TRAXXAS TRX4 Trail Crawler platforms by GPM (TRX4010/23MM). The adapters move the wheel mounting point outward to widen track width and reduce the wheel to chassis gap, helping the tyre sit nearer the body for improved lateral contact.
The adapters locate between the wheel hex and the hub or driveshaft end, maintaining front CVD and rear driveshaft connection while increasing lateral track. The added 23mm thickness, approximately 18mm thicker than the reference hex, modifies wheel offset to improve chassis stability during slow-speed technical crawling.
Fitting is straightforward: remove the existing wheel hex, install the adapter onto the hub or CVD stub, then refit the wheel and fasten the hardware. Manufactured from aluminium for strength with controlled mass, these adapters are available in multiple colours to match a build or speed up identification during setup. Intended for RC-scale use only.
Included hardware from the product source: Stainless steel screw shaft M4*2.5*11.8 – 4 pcs, 5mm shims – 4 pcs, 5mm metal washers – 4 pcs, stainless steel hex socket screw 19mm – 4 pcs.
This item is compatible with
- TRAXXAS TRX4 Defender Trail Crawler
Compatibility with TRX4 hubs
These adapters are specified as an aftermarket solution for TRX4 wheel hex hubs. They conform to the standard wheel hex mounting interface, but verify fit on modified axles or extended CVD setups.
Design impact of 23mm offset
The 23mm offset shifts wheel position outward, increasing track width and changing load distribution to enhance lateral stability during technical crawling. Check driveline articulation after installation on extreme builds.
Supplied components
The kit includes the supplier listed mounting hardware: stainless steel screw shaft M4*2.5*11.8 (4 pcs), 5mm shims (4 pcs), 5mm metal washers (4 pcs), and stainless steel 19mm hex socket screws (4 pcs). Write Product Review Please sign in your account before you can write any review.
