MPS Automatic Air Shifters

MPS Automatic Air Shifter

MPS was the first to develop auto shifters back in 1986. We have refined them over the years and now offer several different combinations. Available for both two and four coil bikes in both auto shift only or auto shifts with integrated engine kill. They are also available with a fuel kill for dry nitrous applications as it avoids the bang of air and fuel igniting in the exhaust that can cause engine damage . The MPS Auto Shift Control is still the best weapon for good consistent runs. Shift points are the biggest reason for inconsistent runs. It shifts at the same preprogrammed point, run after run. Watch the track and your opponent, not a shift light!

MPS Big Cylinder Kit Our shifters come with push in style air fittings. These little jewels are so much nicer to work with than the old fashioned ferrule type that need replaced every time you remove the line. A DOT air bottle is included so you can upgrade to the high pressure system without needing to buy a new bottle. Custom wiring harnesses with a shifter/horn toggle switch are available as an option for some specific bikes to make wiring your MPS shifter a snap. We invented the Auto Shift and the Electronic Engine Kill so we can offer our exclusive, no hassle, free repair or replacement lifetime warranty on them. Be sure to ask about that when buying copycat versions of our products.

Due to popular demand, we continue to offer the MPS Total Package Auto Shifter Kit. Along with the MPS Sport Bike Auto Shifter Kit, you get an Onboard Air Compressor (pn 1-0298), a Horn Button - Air Shifter Control Switch Swapper (pn 1-0317) or Wire Harness, and a MSD RPM Module Kit of your choice. All the most requested accessories combined into one part number for easy ordering and a discounted price.
