Ready to upgrade your Traxxas TRX-4 Trail Defender? These GPM Harden Steel Extended Stub Axles are a popular mod for serious crawler enthusiasts. They're made from hardened #45 steel and are about 12mm wider than the stock axles, which gives your rig a broader, more stable wheel track for better performance on rough terrain. The set includes front and rear stub axles with +17mm hex adapters, perfect for running larger aftermarket wheels. The kit also comes with all the necessary stainless steel screws, washers, and shims for a complete install. They're designed specifically for the Traxxas TRX-4 Defender (model 82056-4) and fit wheels with 4mm thread holes. These axles are tougher than stock, so they can handle the abuse of rock crawling without bending. If you're looking to improve your TRX-4's stability and give it a more aggressive stance, these extended stub axles are a solid choice. Just make sure you've got the right tools for installation!
