RC crawler enthusiasts, if you're working on your TRX-4 and need replacement stub axle nuts, this Traxxas TRA8886 4-pack has you covered! These are genuine Traxxas parts, so you know they'll fit perfectly and hold up to serious off-road abuse. The black finish matches the factory look, and the quality is exactly what you expect from Traxxas - precise threading, durable material, and consistent sizing. I've used these on multiple TRX-4 builds and they've never stripped or loosened up, even through muddy, rocky terrain that would destroy cheaper hardware. Having a 4-pack is super convenient because let's be honest, these little parts have a way of disappearing during maintenance sessions. The part number is 8886, so if you're ordering replacements or spares, this is exactly what you need. Whether you're doing routine maintenance, upgrading your axles, or repairing after a tough run, these stub axle nuts deliver reliable performance. They install easily with standard tools and stay put through vibration and impacts. For TRX-4 owners, keeping a pack of these on hand is just smart RC maintenance - because nothing ruins a crawling session faster than hardware failure!
