  • 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.

About this product

Technical overview

This aftermarket stub axle set is intended for TRAXXAS TRX4 TRAIL CRAWLER applications and carries the model code TRX4017/+12. The axle components are manufactured from hardened steel #45 and are subjected to a controlled heat treatment cycle to enhance surface hardness and long term wear performance for scale trail use.

The extended geometry increases overall track by 12mm compared to the original parts, which improves lateral stability and reduces roll at low speeds. The axles are compatible with wheels using a 4mm threaded hole and are supplied with the hardware detailed below.

Included items and reference: Manual number: 8255+8269, 17mm hex – 2 pcs, 13mm stainless steel hex socket screw – 2 pcs, M4 x 2.5 x 11.8 screw shaft – 2 pcs, 5mm metal washer – 2 pcs, 5mm spring steel shims – 2 pcs.

What steel grade and treatment are used?

Axles are produced from steel grade #45 and undergo a heat treatment intended to increase surface hardness and improve wear resistance under trail loading.

How does the extension impact handling dynamics?

The 12mm increase in track width lowers the centre of gravity effect on roll, providing improved lateral stability and more predictable slow-speed steering response on technical sections.

What hardware is supplied for fitment?

The kit includes two 17mm hexes, stainless hex screws, M4 shafts, washers and spring shims as per the item list above to facilitate correct assembly and preload adjustment. Write Product Review Please sign in your account before you can write any review.
