The Yeah Racing Brass Upgrade set is solid. Close your eyes and imagine the voice over for Arby's "We have the meats!" Now imagine that same voice saying, "S-O-L-I-D" If you want to upgrade your stock TRX4 front axle section, just click purchase. You will not be disappointed!

What reviewers say

Four verified owners rate this brass upgrade set for the Traxxas TRX-4 at 4 to 5 out of 5. Reviewers agree the parts fit well, look good, and are of high quality, with one noting improved handling. The main recurring complaint concerns the documentation and hardware: one reviewer reports no instructions were included, which led to weak support from the website, and describes the hardware as a mixed set of stainless steel and black oxide fasteners. Reviews are few and short, and the set's handling benefit rests on a limited number of owner reports.

  • + Good fit and finish
  • + Quality parts
  • + Improves handling
  • + Attractive appearance
  • − No instructions included
  • − Mixed hardware finishes
  • − Limited website support without instructions
