Shane knows his chit, besides ******* out your parts I'm sure he recommended the correct springs. Nothing reasonably priced can beat the stock rockers with a trunnion upgrade kit...

I just ran into the same problem with patriot springs floating out on me at 5,800 and causing me some hp.

Stock rockers with the trunion upgrade and a PAC-1207X.
