pushrod problems

Summit RacingSummit Racing Verified Purchase

PRO-66878
i put these on my mildly built 302 thinking they would free up a few extra hp, i have about 4,000 miles on the motor and now im having problems with the pushrod ends snapping off in the rocker. not sure what the problem is, my mechanic thinks its because we used the stock pushrods and they fit really tight in the arm...

Beware

Summit RacingSummit Racing Verified Purchase

PRO-66878
Ordered these rockers thinking I could save a few dollars and seeing mixed reviews on proform rockers thought I would chance it. Bad decision rockers were the worst quality you could imagine words cannot do justice. Parts were loose in packaging allowing them to flop around the pin that holds the roller tips were only half installed with about a 1/8 inch of pin hanging out the side of most of the rockers two of the first five I looked at were smashed so tight the rollers wouldn't even turn Thank goodness summit has first class customer service and didn't question the return Thank You Summit. I know we're all on budgets but proform rockers are not a bargain so buyers beware ...read more
