BSB Manufacturing Spring Cups. 6 different style cups are available.
Used to add spring cup to axle tube, fits 3" axle tube. Holds spring up above tube 1/2", designed to space how ever you need and weld in to place.
Fred Ryland inspired 2 1/2" tall spring cup with spring retainer bolts to keep your spring from leaving its perch.
Steel 1" wide clamp ring for a bolt on spring cup. You can weld the cup where you want on the clamp and have it removable. Many other applications for clamp rings also.
David Stremme inspired spring cup raises the spring up to enable you to run the RR shock bulb up and have trailing arm clearance. This cup works with any 5/8” shaft shock or slider
This spring alignment plate works with soft rate springs using the 5" OD to align the spring instead of the ID on our coil over spring sliders and our drop bearing RF spring cup.
