I'm looking to buy some adjustable rockers for a 360. I was looking at some Crane iron rockers and I thought the small blocks used a spring to space the rockers like a big block. The seller says they don't use the springs. Can someone clear this up for me? I haven't been able to find any information on the Web.
Thanks, Kevin

Not sure how old my Crane ductile iron rockers were when I got them last year. They were new, but may have been sitting on a shelf for a long time. They have the separator springs.
On a side note, I did have an adjusting screw break, which is an issue Crane is notorious for having. Invested in a replacement set from Smith Bros.

I personally don't like the springs as it can allow the rocker to walk sideways depending on the situation , the new crane golds I have came with springs  , I'll be switching to soild spacers. Big block have springs because there is a big gap to fill , smallblocks have a lot less .
