The first of their kind to the marketplace, the latest crankshafts from Lunati are built specifically for the
new Gen V (LT1/L83/L86) engines from GM. These cranks are designed to increase engine stroke, which
in turn increases displacement, horsepower and torque. Each crank is available in a 4.000″ or 4.125″ long
or short snout configuration.
All of the crankshafts feature a contoured wing and are fully detailed to reduce windage and regain
horsepower from parasitic losses. The cranks are nitrided and utilize micropolished journals to improve
lubricity and strength for extreme performance applications. The 0.125″ radii journals also increase
strength and power capability. These cranks are gun-drilled to reduce overall weight, and angled rod
lightening holes reduce rotating inertia for maximum horsepower potential and weight savings.
The long snout versions are built for 2014 Corvettes with an LT1, 6.2L V8 with a dry sump oil system
(Z51 package). The snort snout options are designed for the same Corvettes without Z51, along with 2014
Chevrolet and GMC trucks utilizing L86 and L83 engines.
