The last bump stop you'll need to buy. We took everything we've learned, and everything our customers wanted and built it into one product Fully Modular & Adjustable Using hot-swappable inserts, you can adjust MK3's stiffness, height, and even fitment from vehicle to vehicle. You can even alter fitment on the trail, allowing for true fine-tuning of your setup. Next-Level Air-Damping Massive internal air volume allows MK3 to achieve even more energy dissipation than ever. Up to 4x as much damping as MK2, creating a dramatic improvement in ride feel. Extreme Longevity Origami-inspired Yoshimura Polyhedra outer shell is engineered to fold exactly where it's designed to - ensuring compressive stress is distributed more uniformly, significantly improving compression behavior. Sold as one pair, two inserts Optional stiffness inserts can be added to provide a stiffer ride feel. We recommend trying the bump stops without the stiffness insert at first and add them as needed.
