Description
Tapered / Angled Seat Pan Bungs – For Sprung Motorcycle Seats
When a flat bung won’t cut it, our tapered seat pan bungs are the perfect solution for mounting springs on sprung motorcycle seats. Designed with a 20-degree angled cut, these bungs help align the seat springs more parallel to the frame, significantly reducing spring bind and ensuring smoother performance.
Each bung is precision-machined from durable 1" O.D. cold rolled steel, with a short side length of .300" for a low-profile weld. The tapered side is welded directly to the seat pan, offering a clean and functional fit for custom motorcycle builds and fabrication projects.
Product Features:
Sold in pairs
Made from high-strength 1" diameter cold rolled steel
20° tapered cut for improved spring alignment
Short side measures .300" for low-profile installation
Tapped to 3/8"-16 or 5/16"-18 thread sizes
Ideal for custom motorcycle seat fabrication
Made in the USA
Upgrade your seat pan the right way – these angled bungs are a must-have for custom bike builders looking for both function and form.
