A lightweight knockout. A26 is packed with efficient muscle.
The A26 produces up to 515 HP and 1850 lb.-ft. of torque, but its big-bore performance only begins to tell the full story of this engine. The modern simplicity of the A26 design does more than shed weight — every component has been carefully engineered to deliver uncompromising uptime and fuel efficiency, reduced weight and quieter operation.
We stand behind the A26 with a two-year unlimited hours or miles warranty that lets you take it as far as you want, for as many hours/miles as you want. Go ahead, go the extra mile.

The A26 weighs 600-700 lbs. less than 15L big-bore engines.
The Compacted Graphite Iron (CGI) crankcase has greater strength and fatigue resistance than traditional gray iron for thinner walls, reduced weight and maximized payload.
Valve covers are built of a durable, lightweight composite instead of aluminum.
The shot peened aluminum flywheel housing delivers high strength with impressive weight savings over traditional iron flywheel housings.
The simple, single stage design of the turbocharger eliminates several major components, reducing weight and complexity.
