I'm trying out these coil spring inserts. They aren't tennis balls, they're Prothane Coil Spring Inserts. About 40 year ago they were called Haga Balls and Score considered them a secondary suspension. I'm using them as bump stops mainly, the HP 44 i'm working on has no real estate for the standard poly bump stops, so I'm gonna see how these work out. I also switched to a linear rate, lighter rate, coil spring. So I'm planning on these being a secondary spring. The have zero rebound effect, which is a plus. I have 5" up travel, these inserts make contact at 2 1/4". My Duff Long Arms contact the bottom of the frame at 5" up. They haven't hit yet, but I haven't trail tested it much. I made upper and lower landings for them to ride on. I'm running a 10 1/2" and a 2 1/2" insert stacked. My coil springs are 5 1/2" lift, 19" of spring at ride height. 13" of inserts, 3 3/4" of landings.
