Your cart is empty.Billet Rack Cap (also sometimes called the rack plug), made of the highest quality Billet Aluminum, allows full rack travel of the Bosch P7100 injection pump. The Attitude Rack Cap is drilled to 17mm, which is 4mm deeper than a stock rack cap. This allows for full 21mm of possible rack travel which provides more fuel flow, equating to 20+ more HP. Fits on all Bosch P7100 pumps

Made well and good threads have to grind the case or pull the pump to get it on. To get full rack travel you will need to do the afc washer mod, and remove the fuel plate or to get close to full travel run a 0 plate. Best of luck, all the mods are cheap to do and will make your truck run like a new one. Be careful with to much power on automatics can burn up the transmission.
