Nice spring kit,
Significantly superior quality valve train components. This spring set helped resolve my coil binding issues, reduces weight from the valve train and makes me smile every time the rocker cover comes off
I highly recommend these springs. I had the exact problem described in the tech blog resulting in bent pushrods and a broken rocker. These springs resolved those issues.
