Valve Keeper Pioneer PF555HD200
15 February 2024
Pioneer PF-555HD Valve locks are awesome!
Been using this brand of valve locks for nearly 30 years, never had a failure. Used them on stock engines on up to solid roller big blocks with .700 lift. The price became inflated the past few years, but the quality hasn't changed.

Easy to use
Seller upgraded me to Version 2. I Have yet too explore all the features, But what I have experienced so far has been great. Great product for the price.

Perfect Circle are the perfect choice.
Perfect circle has always had great brand name products in there boxes, these were Clevite bearings from back in the day when they were allowed to make bearings correctly in the U.S.A. Since they are no longer around as perfect circle, there quality didn't go down like most current bearing manufacturers.
