4322 Solo seat hinge. Black chromoly

Biltwell’s solo seat hinge is a rugged, well-engineered piece of hardware for custom builds. The seat bracket itself is made from investment cast steel, while the frame pivot is constructed from black electroplated 4130 chromoly steel for maximum durability. Designed to fit the mounting studs on most solo seats, this hinge is a go-to for bobber and chopper projects. The pivot bracket is left unfinished, allowing you to weld it directly to the frame's backbone without any extra prep work. It includes a grade-8 Allen cap shoulder bolt that threads into the opposite side, creating a smooth and incredibly durable hinge pin that will stand up to years of riding.
