PRI 2013: Lunati’s Full Line of Rotating Assemblies

Regardless if you are building a new engine on a budget or looking for parts that will handle well over 1,500 hp, Lunati has you covered with their wide range of rotating assembly packages.

Starting with their sportsman Voodoo line, Lunati’s rotating assemblies are based off a 4340 non-twist crankshaft that is nitride heat treated and also features mircopolished journals. Lightening holes in the rod journals reduce crankshaft inertia weight for faster acceleration and ease of balancing.

The Voodoo H-beam connecting rods also come as 4340 forgings that have been heat treated, stress-relived, shot-peened, and magnafluxed. These processes stress relieve the rods so they are ready to go as soon as you bolt them into your engine. All Voodoo rods are weight matched to 1 gram and use ARP 2000 7/16″ rod bolts. In rotating assembly form, Lunati pairs their Voodoo crank and rods with Icon forged pistons and rings along with King or Clevite bearings.

If premium parts are required, then look no further to Lunati’s Signature Series. A similar 4340 steel forging comes with all the same features as the Voodoo line but is also gun drilled, lightened and contoured. Drop pocket oiling ensures maximum connecting rod oil pressure while fully detailed counterweights with contoured wing help reduce windage. The 4340 aircraft quality steel Signature Series rods come in I-Beam form that have also been shot-peened, magnafluxed, and sonic tested. The Signature Series rotating assemblies can be paired with either premium I-beam or H-beam rods, Mahle or Diamond pistons, and King or Clevite bearings.

Rotating assemblies are offered in popular LS, big block Chevy, small block Chevy, and small block Ford displacement combinations.
