Mopar Performance Roller Rockers

The Proform rocker information is listed on their website and states," Not to be used with lift over .600" and spring pressures greater than 450 lbs. open. I have also read on a few other websites that the machine work is terrible on them. On a side note another friend of mine tells me the ones 440 Source sells are very poor quality as well. Sadly there are no cheap quality options, but then cheap and quality are never used together in the same sentence. For a 440 you have three distinct price points. Cheap/ poor quality/ Chinese with limited performance capabilities $300-$400, Hughes which will take care of most needs for $770, and finally Harland Sharp, Jessel, T&D for $1148 to $1250. Of all the rockers available it's hard to beat a set of Hughes for the quality and price point.
