Samix Aluminum Knuckle for Traxxas TRX-4 (Grey)
Went with aluminum over brass bc I don’t get into super serious crawling. I like to trail and just mess around. So I couldn’t justify the cost of brass. The aluminum gives me more strength and looks really great. I replaced portals and hubs all the way around with Samix grey aluminum and I couldn’t be happier with the way it come together.

Samix Aluminum Knuckle for Traxxas TRX-4 (Grey)
I upgraded the plastic knuckles to improve steering performance and precision over the stock plastics. Over time the plastic linkage attachment eventually become soft with the constant demands placed by the steering servo that causes increasing flex and reduces steering precision.
This mod fits to the stock plastic outer portal cover and comes with 2 spare 2.5mm driveshaft bearing retaining screws incase you loose the old 2.5mm screws. You will need to use the remaining old stock screws to complete the installation.
Overall the quality is really good and all parts fit precisely including the bearings without slop. I am very happy with the purchase.
