Lunati Offers 6-Counterweight Signature Series Big Block Chevy Crankshafts

Released: 1/11/2015 10:45:45 AM

Olive Branch, MS – New lightweight versions of popular Signature Series crankshafts are now available from Lunati. They feature six counterweights instead of the eight found in most Big Block Chevy cranks.

Lunati 6-Counterweight Signature Series Crankshafts are designed without center counterweights, thereby allowing the engine to rev faster. They are nitrided with micropolished journals to increase lubricity and strength in extreme performance applications. Each crank features a 0.125" main and rod journal fillet radii to increase strength and power capability. A contoured wing also diminishes windage in the crankcase and frees up lost horsepower from parasitic losses. Lunati 6-Counterweight Signature Series Crankshafts are gun-drilled to further reduce weight and have a lightened rod pin for decreased mass and rotational inertia. They are designed for Big Block Chevy applications featuring two-piece rear seals. Each crank weighs 67-68 pounds depending on stroke and length of counterweight.
