Description

Update 02/28/25:  For those that have these on back order with us, Eagle is saying those orders should be filled on/around 03/31/25.  They’re also stating that orders placed now, should be filled around 05/09/25, and that date will extended as time passes.  They’re NOT confident that they will produce these to the point of having “shelf stock” in the future due to decreased sales.  Get your orders in here/elsewhere!  It’s unlikely that these cranks will become and “order-and-ship-now” part in the future (like many parts for our beloved cars)!

Exceptional quality at a reasonable price.

These forged 4340 steel crankshafts from Eagle Specialty Products are great for high-performance applications. They feature non-twist forging, go through a multi-stage heat-treatment process, and are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed, and sonic tested, so you know you’re getting a top-quality piece. Each crankshaft has cross-drilled and chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength, and the journals are precision-ground and micro-polished to less than 5 RA. A target bobweight of +/- 2 percent greatly reduces balancing time.

Stroke: 3.465″ (88mm)

Notes: Stock Stroke for 4G63 6-Bolt Engines.
