  • BLP Down Leg Boosters

    BLP 4150 down leg boosters are machined from a high hump heavy duty blank. The booster leg is sized with a special ball nosed reamer to ensure better fuel delivery. The modified boosters have a special machined radius in the center and the outside is machined for uniformity and better air flow. This machining is not allowed in some classes and is not performed on the "legal boosters". The last 3 digits of the part number indicate the booster leg size.
