If you're serious about performance, you know the crankshaft is the heart of your engine. Since 1968, Tomei has been all about tuning and racing in Japan, and they've built a reputation that speaks volumes in the motorsport world. Their crankshafts are designed with the kind of attention to detail that only comes from years of experience on the track.

Let's talk about what makes the Tomei crankshaft stand out. First off, it's a hefty piece of machinery—16.8 kg of solid engineering. With a 98.0mm stroke and crank pin and main journal sizes of 52mm, you're looking at a component that's built to handle the extreme demands of performance driving. This isn't just a factory part; it's made to withstand the kind of stress that comes from racing, where RPMs can spike and throttle transitions are rapid.

Factory crankshafts are typically designed to save costs and last through everyday driving, which is the opposite of what we want when we're pushing the limits. Tomei's crankshafts, on the other hand, are forged or machined from billet steel, giving them a strength that cast pieces just can't match. The forging process creates a grain structure that enhances durability, and every crankshaft is meticulously balanced to minimize vibrations that can lead to engine wear.

Whether you're hitting the streets or the track, you need a crankshaft that won't let you down. Tomei's products are engineered to strict tolerances, which means you can count on optimal fitment and airflow. This is crucial because even the smallest misalignment can lead to catastrophic failures. With Tomei, you're getting a component that's been tested and proven in nearly every motorsport imaginable.

For those of you with a Mitsubishi EVO10 from 2008 to 2016, this crankshaft is a perfect match. If you want to dive deeper into the installation process, you can find the instructions here.
