Trask Stage 1 Original Turbo Kit - $5,590


Send me more information about this product:



The Original Turbo Kit features a stock like exhaust with a right side, single exit pipe. A false dual exhaust pipe is available for FL models which will keep the exhaust looking symmetrical from the rear. The OG features a clean and sleek internal wastegate setup.

TRASK Turbo Kits will boost the horsepower on your Harley Davidson motorcycle about 40-50% more to the rear wheel!  Our Harley Turbo Kits are 100% bolt on and do not require any modifications to your stock engine when running 8lbs of boost on 91 octane pump fuel.  Our Harley-Davidson turbo systems make peak HP and TQ right where you need it, between 3,000 and 4,000 RPM. For Monster gains our kits are capable of making 120-300 HP to the rear wheel (depending on engine size, fuel quality, Stage 1 or Stage 2 kit, & application).  Application is everything, turning up the boost means engine upgrades may be required.  All Trask Turbo Kits require the use of a Thundermax ECM which is purchased separately.  Trask can provide the Thundermax with your turbo kit preloaded with the proper base map.


Twin Cam Turbo Kit installation instructions can be found HERE.

    M8 Turbo Kit installation instructions can be found HERE.

    Turbo Kits available for almost all Twin Cam and M8 Harley-Davidsons including Road Glide, Street Glide, Dyna, Softail and Road King's.

    *Don't run any fuel additives, octane booster or leaded race gas with kits, it will burn up the oxygen sensors and ruin the map in the Thundermax. Lower Fairings and some aftermarket highway bars are not compatible with our Turbo Kits.  2020 RDRS equipped bikes may have check engine lights on until software updates are available.
