RipTide Metal Dropthrough Backing Plates 105: Secure Your Ride with Aircraft-Grade Strength Tired of flexing decks, uneven pressure, and hardware pulling through your drop-through longboard? Upgrade to the ultimate in security and performance with the RipTide Metal Dropthrough Backing Plates 105! These aren't your average washers—they are precision-engineered, 1/8" thick (3.2mm) plates crafted from premium Aircraft-Grade Aluminium. Designed specifically for drop-through truck mounting, these plates are an essential addition for any serious longboarder looking to maximise their setup's durability and responsiveness. Key Features & Benefits: Ultimate Deck Protection: The generous size of these backing plates dramatically spreads the load across a larger surface area of your longboard deck. This prevents wood deformation, compression, and cracking caused by the intense leverage of drop-through trucks, especially on softer woods or flexible composite decks. Optimised for Dropthrough: Specifically contoured to fit neatly under drop-through baseplates, ensuring a flush, perfect fit that standard washers simply cannot replicate. Aircraft-Grade Aluminium: Constructed from high-strength, lightweight 1/8" Aircraft Grade Aluminium (104 Series), offering maximum stiffness and corrosion resistance without adding unnecessary weight. Secure Hardware: Provides an incredibly solid foundation for your mounting hardware, preventing nuts/bolts from pulling through the deck and ensuring your trucks remain perfectly aligned and tight. Enhanced Performance: By stiffening the area around the trucks, these plates contribute to a more responsive and stable ride, translating to better control during slides and high-speed carving. ⚙️ Product Specifications: Feature Detail Material Aircraft-Grade Aluminium Thickness 1/8" (approx. 3.2mm) Compatibility Universal Dropthrough Truck Mounts Function Deck Protection, Hardware Support, Stress Distribution Weight Lightweight (Minimal impact on setup)
