This Rotating Assembly is designed for LS3 / LS9 / L92 / L99 Engines and makes 416 Cubic Inches. It features a K1 Technologies Forged 4340 4.000" Stroke Crankshaft, K1 Technologies Forged 4340 H-Beam Rods with 7/16" ARP 2000 Rod Bolts and your choice of Wiseco Pistons. These Pistons are the strongest shelf stocking Pistons available for the LS-Series Engines and come standard with Wiseco's Armour Glide Skirt Coating and Wiseco's GFX Ring Set. The GFX Ring Set is designed to handle any amount of Boost and / or Nitrous. These Rings feature a Steel Nitrided Stainless Steel Top Ring and a Napier 2nd Ring which helps with Oil Control. 4130 Chrome Moly Pins come standard with an option to upgrade to 9310 Alloy Pins which we suggest at the 800 HP range for extra insurance.
*Reluctor Ring - We offer both 24x and 58x Reluctor Rings. While all LS3 / L92 / LS9 Engines use a 58x Reluctor, we know some customers will be using this Rotating Assembly in an Earlier Model Vehicle. Below is a list to help you select the correct Reluctor Ring for an Earlier Model application.
ALL 1997 - 2004 LS1 - 24x
ALL LS2 GTO's - 24x
2005 Corvette - 24x , 2006 / 2007 - 58x
2006 / 2007 CTS-V - 58x
2006 TBSS - 24x , 2007 - 2009 - 58x
*Balancing - We offer Digital Balancing for all Rotating Assemblies we sell. While some shops will just measure 1 Rod and 1 Piston to get the Bobweights for the Crankshaft, we do NOT! We start by Weight Matching all Rods (Big and Small End) and Pistons (with Pins) to a tolerance of +/- 0.1g
The Crankshaft is then Balanced to a Tolerance of 0.2g
