Richard SchwenkVerified owneron Traxxas Hoss/Rustler/Slash 4x4 Extreme Heavy Duty Suspension Upgrade Kit

I put this set on my Slash 4x4 that is 5 years old that was overheating/thought was ready for.retirement and it is better than brand new. The larger bearings in hub make it extremely smooth. Traxxas plastic is still not the strongest..I broke one of the arms and the bolt on tower snapped the hole but all in all this set.is worth it.

This looks to bring the suspension/ drivetrain to the strength of the maxx or xo 1, best option imo for power greater than the vxl3 system for slash, rustler, hoss

Tommy Quirozon Traxxas Hoss/Rustler/Slash 4x4 Extreme Heavy Duty Suspension Upgrade Kit

Traxxas did really good with this kit I have it in all my 4x4 rcs and I bash them really hard and I can tell they handle way better than rpm and tekno parts DONT WASTE YOUR MONEY OR ROM OR TEKNO BUY THIS INSTEAD!!!

What reviewers say

Reviewers report that the kit improves smoothness and handling on Traxxas Slash, Rustler and Hoss 4x4 models, with one owner noting larger hub bearings make a five-year-old vehicle feel better than new. Another reviewer compares it favourably to heavier-duty drivetrain options for high-power setups. Reviewers agree the kit adds durability for hard bashing. One reviewer notes that stock Traxxas plastic remains fragile, reporting a broken suspension arm and a snapped tower bolt hole. Comparisons to RPM and Tekno parts appear in one review, and the set of reviews is small.

  • + Smoother operation from larger hub bearings
  • + Improved handling when bashing hard
  • + Stronger than stock suspension and drivetrain
  • − Stock Traxxas plastic still breaks under stress
  • − Bolt tower hole snapped in one report
