    66929 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Good addition Product arrived with several other items I purchased, when I opened the box the packaging for the rockers had opened up during transit/delivery and the rockers and poly locks were loose in the box and scratched up. Other than than that the rockers function well and installed as they should. For a regular street motor I would have no problem recommending these but for a high output motor I would not recommend as they are bulky and somewhat heavycompared to other roller rockers I have used in the past.
