 Crankshaft features OE-style reluctor ring installed and checked for runout prior to packaging, and roller pilot bearing is included with crankshaft. Must use OE-style bearings for 2005 & later models. 

"ESP" forged 4340 steel crankshafts feature a non-twist forging and undergo a multi-stage heat treatment process, as well as stress relieving, shot peening, and nitriding. Cranks are magnafluxed and sonic tested to insure quality. Eagle micro-polishes each journal to a 3 or better R.A. The .125" radius is used to increase strength, so chamfered or narrowed bearings must be used.

All rod throws feature lightening holes to reduce weight. All Chevrolet "LS" series forged 4340 cranks are internal balance. Target bobweight GUARANTEED +/- 2%. Crank specs are as follows:

• MAIN JOURNAL: 2.559"
• ROD JOURNAL: 2.100"
• STROKE: 3.622"
• BOBWEIGHT: 1800
• MIN ROD LENGTH: 6.100"
