Product Details
Starting with a 4.000-inch stroke, this Manley Pro Series crankshaft is forged from 4340 alloy steel, a material chosen for its excellent strength-to-weight ratio. This isn't just any piece of steel; it's a non-twist forging that's been put through a multi-step heat treatment and nitriding process. This treatment significantly boosts its strength and ensures it can handle the demands of a performance engine over the long haul.
You'll notice the attention to detail in its lightweight design. Manley has gun drilled the mains and lightened the rod journals, all contributing to a lower overall weight. This reduction helps optimize your engine's performance. The counterweights are also fully profiled, meaning they're shaped precisely for balanced stability. To further reduce friction and improve how smoothly everything spins, the large radius journals have been micro-polished. This level of finishing is crucial for longevity and performance.
Before it ever leaves Manley, each crankshaft undergoes rigorous quality checks. This includes stress relief, shot peening for fatigue resistance, and 100% magnafluxing to catch any potential flaws. This thorough process ensures you're getting a well-built component that meets their high standards for your Chevrolet LT1 engine.
