The Samix Traxxas TRX-4 Brass Steering Knuckle is a precision machined steering knuckle option that adds 102 grams of unsprung weight to the front of your TRX-4, for improved forward weight bias and performance. Unlike other brass parts, these feature a stealthy black finish, with chamfered edges that give the parts an unmatched look that offers a touch of bling to your scaler. 

Plus, when combined with the Samix brass c-hubs (SAMTRX4-4014 - not included) and portal covers (SAMTRX4-4413C2 - not included) you have the ultimate brass upgrade package that will dramatically improve the performance of your TRX-4


  • Brass knuckle adds 51g per side
  • Better center or gravity and forward weight bias for climbing
  • Improved durability and rigidity over the factory parts
  • Made of high quality brass and etched with L and R for ease of installation
  • Compatible with Traxxas parts
  • Black coating to help prevent corrosion

Samix Traxxas TRX-4 Brass Steering Knuckle
Fit and finish is perfect. I have all the Samix brass upgrades for the TRX-4 and they are amazing. With A-Main getting them to me in 2 days made it even better!
