they are the rockers with the lowest ratio of lift. Which isnt really good.... They are forged while the others are either pressed steel or sintered. but the pressed steel ones are more than up to the job, especialy after being welded on the top. They have been tested up to 9300 rpm by myself.

i had a set of forged ones on me rally x car, they had been filed down to make em lighter, really old school shit, i know if ure running Phase 2 cam, the ratio for best results are 1:3 and the pressed steel rockers are this ratio (if ure trying to save a wee bit cash)
