If you're tired of breaking stock drive shafts on your Traxxas Rustler or Hoss 4X4 VXL, these GPM upgraded axles are exactly what you need! Made from hardened #45 steel with 6061T6 aluminum bodies, these things are seriously tough - way stronger than the original parts that come with your RC car. The CVD design gives you super smooth rotation and better power transfer to the wheels, while the retractable design actually gives your suspension more space to work properly. They come as a complete pair with all the necessary hardware including screw pins and O-rings, so you've got everything needed for installation. The bright orange color looks awesome too - not just functional but actually makes your RC car look more aggressive. Whether you're bashing around the backyard or hitting the track, these axles can handle the punishment that breaks stock parts. Honestly, if you're running your Traxxas hard and finding the factory drive shafts can't keep up, this upgrade is totally worth it for the durability and performance improvement!
