The Voodoo® Small Block Chevrolet 383 Stroker Crank and Rod Kit from Lunati® combines high-quality components with an affordable price. Each kit includes a 3.750" stroke Lunati crankshaft, 6.000" long “stroker” H-beam connecting rods, and premium main and rod bearings. Lunati crankshafts are made from non-twist forged 4340 steel alloy for strength and durability and feature lightening holes in the rod journals for reduced crankshaft inertia and increased acceleration. They are nitride heat-treated and finished with micro-polished journals. Lunati’s Voodoo H-beam rods are also made from forged 4340 steel, CNC-machined and fitted with ARP2000 rod bolts. Each Stroker Rod and Crank Kit ships with premium rod and main bearing kit. Main bearing kits are for a two-piece seal.
