Why Upgrade to Cobra Racing Lower A-Arms?

Whether you’re launching off massive jumps, tearing through rough terrain, or dominating the track, these upper A-arms will keep your X-Maxx performing at its peak.
Compatibility
These Cobra Racing Aluminum Upper A-Arms are designed to fit the Traxxas X-Maxx 8S (standard) model.
