The PRW 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift camshafts and are much stronger than die cast aluminum or stamped steel, so rocker arm flex is negligible. The roller tip minimizes scrubbing (the result of the valve stem pushing hard against the valve guide), reducing friction and freeing up an additional 15 to 30 horsepower over stock rockers.

The rockers and balls seem ok, but the poly locks were waaaayyy too short for even stock length studs. Also the kit came incomplete, it’s missing half of the balls..

Needed self aligning rockers for replacement heads, these are good quality at a fair price. I'd buy again when needed.

After about 300 miles, I had 4 failures. The cup where the pushrod resides deteriorate to the point of eroding the end of the pushrod.

If i could leave no stars i would. Long story short, i had to keep resetting the bolt and in the end the "4340" steel busted.

I bought theses because of a review and since the I've found several negative reviews. I wish I had found those negative reviews before I bought. Out of 16 rockers two of them are no good and must be replaced. That wouldn't be so bad but the time to deal with this is far more expensive than the rockers.
