What is the primary benefit of using a 4340 billet steel crankshaft?

4340 billet steel is chosen for its exceptional strength and ability to withstand high stresses and temperatures. This makes the crankshaft more durable and reliable under demanding performance conditions compared to cast iron or other materials.

What does the 82mm stroke signify for my engine?

An 82mm stroke means the crankshaft has a longer throw than the stock unit. This increases the engine's displacement, which can lead to improved torque and horsepower, especially when paired with other performance modifications.

What other components are typically needed when installing a new crankshaft?

When installing a new crankshaft, it's crucial to have new main bearings and rod bearings, as well as new seals. For optimal performance and reliability, it's also recommended to have the crankshaft and the entire rotating assembly professionally balanced.
