BTR Forged Crankshafts

Brian Tooley Racing's premium 4340 forged crankshafts are available for serious street and race LS engines. Each crank is core-hardened using nitride for improved strength, bearing life, and size tolerances held to +/- .0002 in. BTR has either a 3.622 in., 3.900 in., or 4.000 in. stroke, along with three different reluctor wheel options—including standard factory 24 and 58 tooth wheels, or an upgraded 24 tooth billet wheel. A standard wet sump snout and 6-bolt rear flange will allow you to bolt on your factory balancers and flywheels/flexplates or the many aftermarket pieces offered.

Product features include:

* 2.100 rod journal diameter
* .125 in. radius on both the connecting rod journals and main journals for increased strength
* Chamfered oil holes for improved oiling
* Leading edge chamfer and radius on counterweights
* BTR balanced rotating assembles are available separately

NOTE: BTR crankshafts require an OEM style, one-piece crank gear.
