This is a pack of four optional Competition Suspension Aluminum Shock Spring Cups, intended for use with Mugen 1/8 scale vehicles. CSI shock spring cups have been CNC machined from high quality aluminum and lightened to provide the lowest CG possible at the rod end, while remaining incredibly lightweight. Additionally, they have been engineered so that the spring will "clip" over the end of the cup retainer helping to prevent the spring from coming off, which can negatively affect your race cars performance and handling.

Competition Suspension Mugen Aluminum Shock Spring Cup Set (4)
I had a feeling when looking at the pic of these, they weren't going to stay on very well. They don't sit deep enough onto the collar/ball link piece and on high jumping, the spring can't keep them in place unless it's set real stiff. If I didn't zip tie each one to its spring, I probably would have lost one. On the front shocks, it hasn't been a problem yet. Just the rears so I'm putting the stock Mugen part back on the rear shocks and leaving these on the front. Also, it's described that these would "snap" into the spring keeping them tight. They don't fit tight in the spring, at least mine don't and that's even with the CSI springs I ordered. These are very nicely made though. Very good machine quality. All they really need is just to be deeper where that plastic piece goes in at the bottom. It's not even 1/16"? It needs to be probably 1/4".
