Features & Benefits:
* Heat-treated 4140 material is harder and 114% stronger than stock
* Harder material, eliminates thrust washer
* Larger 1.671in. diameter crankpin
* Designed with increased cross-sectional area for increased crank-pin clamping force – No welding required!
* Integral mainshafts – Eliminates two potential points of weakness
* Consistent balance and precision machining – Truer flywheels and less vibration
* Reduced mainshaft deflecti on at high rpm – less vibration, reduced piston and rod side thrusting, prevents oil pump damage, fully compatible with gear drive cams
* Capable of higher rpm – More available power!
* Trued to with in .0005in. TIR
* Rod Bearings have 20 rollers vs 18 stock
Tech Tip:
* Does Not Fit Dyna 2006.
