Harley-Davidson Dyna Stunt Parts: Protection & Setup Guide
Explore Harley-Davidson Dyna stunt parts: K Bars, cage kit stages, shock sliders, derby covers, and subframes, with fitment guidance for 1992–2017 Dyna models.
The Harley-Davidson Dyna has a longstanding following in V-Twin stunt riding. Its exposed chassis, twin rear shocks, and aftermarket support make it a versatile starting point for performance and protection upgrades.
Before ordering, make sure you know your Dyna’s setup. The complete Kruesi Originals Dyna Cage Kit is designed for 1999–2017 Twin Cam Dyna models equipped with mid controls. Riding a 1992–1998 Evolution Dyna? Our standalone Dyna K Bar offers fitment for those earlier models as well. Not compatible with forward controls. Always double-check your motor mounts and existing modifications to ensure everything fits your build.
Whether you're putting together a dedicated stunt bike or adding protection to your everyday ride, this guide explains the key components and where they fit in your build. Shop Dyna Stunt Parts →

7. What Should You Buy First?
1992–1998 Evolution Dyna: Start by evaluating the standalone K Bar and any other individually confirmed compatible accessories. The complete Dyna Cage Kit is not listed for these motorcycles.
1999–2017 Twin Cam Dyna: Compare Cage Kit Stages 1–4 based on the areas you want to protect. Confirm control layout, motor mounts, model-year specifics, and aftermarket compatibility before ordering.
Building in stages: Consider engine and frame protection, then primary-side and shock protection, before planning any specialized rear subframe setup. Individual parts and the Cage Kit may not always be interchangeable across different builds.
