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
Technical overview of brass axle mounts
The TRX4089X brass axle mount set is a precision replacement for TRAXXAS TRX4 Trail Crawler axle link and damper pickup points. Each brass mount offers several threaded locations to allow controlled changes in link height and damper angle while adding axle ballast for improved low-speed traction.
The kit contains four brass mounts plus stainless steel flat head screws and is intended to clamp to the axle housing without the need for axle modification. The multiple tapped holes let experienced builders tune effective link lengths and roll centre by relocating link and damper pickup points.
Install by positioning the mount on the axle tube, aligning link and damper pickup, then securing with the supplied screws through the selected threaded holes. This approach provides repeatable adjustment points for articulation, roll control, and weight distribution during setup and testing.
Compatible Models
- TRAXXAS-1/10 TRX4 DEFENDER TRAIL CRAWLER
- TRAXXAS-1/10 TRX4 TACTICAL UNIT-82066-4
- TRAXXAS-1/10 TRX4 FORD BRONCO 82046-4
- TRAXXAS-1/10 TRX-4 BLAZER 82076-4
- TRAXXAS-1/10 TRX-4 MERCEDES-BENZ G500
For precision tuning of link geometry and axle ballast on TRX4 crawlers, these brass mounts offer a reliable, repeatable upgrade without permanent axle modification.
What hardware is included for mounting?
The set includes four brass axle mounts and stainless steel 2.5×10 flat head screws for front and rear installation.
How do I use the threaded positions for tuning?
Select different tapped holes to change link pickup relative to the axle tube; this alters effective link length and damper angle, which in turn affects roll centre and articulation.
Is axle modification required?
No permanent axle modifications are necessary; the mounts are designed to clamp and be secured with the supplied screws for reversible installation. Write Product Review Please sign in your account before you can write any review.
