Brian Crower Crankshaft - Toyota 3URFE 108mm Stroke 4340 Billet

This is a Brian Crower 4340 billet crankshaft specifically made for Toyota 3URFE engines. It features a 108mm stroke, which is an increase over the stock dimension, allowing for a larger displacement and potentially more power when building a performance engine. If you're looking to rebuild or significantly upgrade the bottom end of your 3URFE, a strong crankshaft like this is a foundational piece.

Brian Crower is known for making well-built internal engine components, and this crankshaft is no exception. It's forged from 4340 billet steel, a material chosen for its exceptional strength and durability under high stress. This makes it suitable for builds that will see significant performance use, whether that's for racing, heavy towing, or just pushing the limits of a naturally aspirated or boosted setup. The 108mm stroke is a common upgrade for these engines, offering a good balance between increased displacement and maintaining reliable engine geometry. This part is designed to be a direct replacement for the factory crankshaft, though it's intended for performance applications where other supporting modifications will likely be made.

When installing a performance crankshaft like this, it's crucial to ensure all related components are up to the task. This includes balancing the rotating assembly, using appropriate pistons and connecting rods, and ensuring your engine block is properly machined and clearanced. Always refer to the manufacturer's installation instructions for specific details regarding bearing clearances, assembly procedures, and any required machining. This crankshaft is a significant investment in your engine build, and proper installation is key to unlocking its full potential and ensuring long-term reliability.
