Hey Craig, I had that shock rebuild kit from for my Losi Highroller laying around and decided to try a bucket out and see if it eliminated the spring rub.

It didnt seem to seat the spring properly allowing the bucket to move/swivel easily, while constantly getting uncentered. If there is an impact or tumble it seems like the spring will move excessively, rendering them less effective.

Should I tighten or shorten up a bit the shock rod ends to add more pressure to the spring, possibly eleviating my issue? Did you run into a similar problem with the cups/buckets? I did read your previous post about making sure they are centered correctly, but do they move easily to your touch?

Thanks for any input in advance.
