Ready to take your FMS FCX10 LC80 or K5 RC crawler to the next level? These 112mm threaded aluminum shock absorbers are a game-changer for suspension performance. CNC-machined from 6061 aluminum, they're precise, durable, and fit perfectly on your FCX10 series truck. The threaded body lets you fine-tune the ride height and damping, so you can set it up just how you like for different terrains. The kit includes two shocks plus both soft and hard durometer spacer washers, giving you options to adjust preload. They come pre-assembled with all the hardware you need for a straightforward bolt-on install. The hard-anodized finish resists scratches and wear, and the seals are quality enough to prevent leaks. For the best performance, we recommend using 8000wt shock oil (not included). Whether you're crawling over rocks, trails, or backyard obstacles, these shocks provide smoother control and better handling. Upgrade your rig with confidence—these shocks are built for serious crawling fun!
