Yella Terra Rocker Arms LS1 (new style)
 

these are the new style rocker arms part number 6645. there is so much demand for these bad boys that they are on back order.... unfortunately, i ordered 2 sets by accident and since i let them sit in my garage (came in one box so i didn't realize i ordered 2) i cannot return them because the store's policy. i payed a tad over 400 so i'll just set my price at 400obo... looking for a local sale

look at what people are saying about them:
