AT-Mini Suspension Truck, Failure, and Version 5

Version 4 failed due to over-constrained bushings, but Version 5 changes the preload method and is holding up so far. Version 5 introduces a spacer and lightly preloaded inner nuts to prevent the springs from being crushed when tightening the wheels. Early riding tests feel solid and quiet, though the extremely short wheelbase presents new design challenges. This is an ongoing engineering and prototyping series focused on compact suspension skate trucks, failure analysis, and iterative design. 🛹 Longboard Technology - Support the Channel! 🛹 🚀 Subscribe to stay up-to-date with the latest longboarding videos: https://tinyurl.com/SubscribeToLongbo... 💰 Show your support through PayPal donations: https://tinyurl.com/DonateToLongboard... 🤝 Become a valued patron on Patreon:   / longboardtechnology   🎁 Explore our Amazon Wish List and help keep our projects going: https://tinyurl.com/SupportLongboardP... 📺 Navigate through our playlists for specialized content:    / @longboardtechnology
