Yup, Get the most steering possible with this upgrade. It must however be used with the GPM Steering Kit *or other steering upgrades) and Tamiya Universal swing shaft. If using the Stock hub carrier you must cut off the steering stoppers and grove that section a little. This in no way afqfects the performance or durability of the hub carier. It only allows it to move further in order to increase the steering. You will also need to shorten the steering links, I strongly suggest using the short Traxxas links.
The picture shows Alu,inum ones but on Shapeways its only the Black Metal or White plastic ones that are available.
