Product Reviews

  • "very simple and easy install"
    David H. Strictly Diesel Dipstick Adapter Repair Kit
  • "Had shift flare between 3rd and OD, got the package with filter and valve body and love the way it shifts now. Great product and a great price."
    William H. John Wood Valve Body
  • "Just installed this thing on my 05 F250. And wow.. combined with just the MileageXS tune from my Superchips Flashpaq F5 1845 it now has some crazy snap at all ends of the power band. Going to try it out on the hot tune tomorrow. I can only imagine the insane gain it’ll give me. Mind you I’m just running a MBRP turbo back exhaust with stock cat and a custom coated banks intercooler with honed out intake elbow to eliminate airflow turbulence and volant intake and obviously the FASS Titanium Water/Air preparator with sump kit. This beastly thing now is able to go from fifteen to 70 in just a few seconds and yet still getting better mileage than a big block ever will. Torque It to Launch It🤘"
