If you're into RC crawling and want to upgrade your HPI Crawler King, these stainless steel king pin screws are exactly what you need. They come in a pack of 4 with dimensions of 4.96x5.4x3.85mm, made from durable stainless steel that won't rust or corrode like the stock parts might. Installing these is pretty straightforward if you're comfortable with basic RC maintenance - just replace your old king pins with these stronger versions. The quality feels solid and they fit perfectly in the Crawler King's steering knuckles. What's great about upgrading to stainless steel is you get better durability and corrosion resistance, which is huge if you run your crawler in wet or muddy conditions. No more worrying about stripped threads or rusted screws seizing up. These small upgrades might seem minor, but they really improve the overall reliability of your RC rig. Whether you're building a new crawler or maintaining your current one, having quality hardware like this makes all the difference in performance and longevity. Definitely a smart upgrade for any serious RC enthusiast who wants their Crawler King to perform at its best!
