The WOD Aluminum Mounting Puck provides a simple, durable, and professional solution for creating threaded mounting points in custom fabrication projects. Precision machined from 3/4" thick aluminum and tapped for a 3/8"-16 bolt, this weld-ready mounting puck eliminates the need to drill and tap brackets, saving fabrication time while delivering a strong, repeatable attachment point. Whether you're mounting a radiator, transmission cooler, fuel cell, battery tray, toolbox, or custom aluminum accessory, these mounting pucks provide clean installation and excellent thread engagement. They are a staple component in race cars, rock crawlers, rock bouncers, Ultra4 vehicles, prerunners, and custom tube chassis builds where strength, serviceability, and clean fabrication matter. Includes: (1) WOD Aluminum Mounting Puck Important: Designed for custom fabrication. Welding should be performed by a qualified fabricator using proper techniques for aluminum components.

Threaded mounting pucks eliminate the need to drill and tap fabricated brackets, creating a clean, professional mounting solution while significantly reducing fabrication time. They also provide consistent thread engagement that makes repeated component removal and installation easier. Strong threads for demanding applications The 3/4" thick aluminum body provides excellent thread depth for the 3/8"-16 fastener, making these pucks ideal for components that experience vibration and repeated service throughout the life of the vehicle. Clean, serviceable fabrication Mounting pucks are commonly welded into custom chassis tabs, brackets, or aluminum structures to create removable mounting points for radiators, coolers, battery trays, fuel cells, and other accessories. Pairing them with rubber isolators or polyurethane washers can further reduce vibration transfer to sensitive components. Built for custom fabrication Whether you're building an Ultra4 car, rock crawler, race buggy, or one-off fabrication project, these threaded mounting pucks provide a simple, durable solution that saves fabrication time while delivering a clean, professional finished product.
