Perry Parts MK3 Rear Stiffness Insert

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.
