Shocktech High Pressure Inline Regulator (HPR) - Black Shocktech inline regulator available in black gloss, silver gloss or raw kit form. Years ago we tried out every inline regulator we could get our hands on. We felt that CP made the best so we hit them up for a private label version. Their internals to go with our outer design. It worked out so well that when it came time to build a new updated version we went right back to one of the best in the biz. High yet very consistent flow rates, our inline regulator will not let you down at the chrono. ** DO NOT USE RAW PARTS WITHOUT ANODIZING **When you purchase raw aluminum parts please keep in mind that you cannot thread them into each other.A raw bomb screwed into a raw front block may seize and never unscrew. This applies to all raw components. The threads are weak and will "roll" or "gall" until anodized. ** ANY RAW PARTS PURCHASED WILL COME UNASSAMBLED **
