For guaranteed fitment on your Surron Ultra Bee, we highly recommend the Sirris rear triangle installed during the shock installation procedure. 

Stock Ultra Bee triangle fitment: The Sirris Shock is designed to offer the maximum possible piston size and still fit within the stock linkage. Tolerances on each stock Ultra Bee vary. Light contact between spring OD and stock triangle may occur. We highly recommend our higher clearance triangle to prevent this.

Aftermarket Ultra Bee triangle fitment: Some aftermarket triangle links may have significant interference that could damage the shock and/or triangle. It’s important to check clearance as you assemble and cycle the suspension.
