    - 3” MM Frame Mount Body Lift

    - Alpha Engine Oil Pan

    - Engine Oil Dipstick on Driver's Side

    - Brand new wiring harnesses

    - All accessories on the engine are new

    - FASS Fuel system

    - Every build is built to USE

    - Over 4 page detailed build list

    - 500 mile road tests before delivery 

    We are only interested in making the highest quality conversions in the game.

    If its worth doing its worth over doing.
