Mishimoto

Mishimoto has built its reputation on engineering performance cooling and drivetrain components that solve real-world problems for hard-working trucks and tow rigs. Founded by enthusiasts, the brand has grown into one of the most trusted names in aftermarket thermal management, delivering precision-built parts that improve durability, lower operating temperatures, and add a serious dose of underhood and underbody style. At Stateside Performance, we carry a curated selection of Mishimoto upgrades designed to keep your diesel or gas truck running cooler and stronger under load.

Our Mishimoto lineup focuses on heavy-duty drivetrain protection, including their popular cast aluminum transmission pans built specifically for the Duramax Allison A1000. These finned pans increase fluid capacity, improve heat dissipation, and add structural rigidity to help extend transmission life during towing, hauling, and daily driving. Whether you're running a stock truck or a tuned workhorse, Mishimoto's components are engineered with OEM-quality fitment and a finish that looks as good as it performs.

You'll find Mishimoto fitments covering a wide range of late-model and legacy trucks and SUVs, including Ford, Chevy, GMC, Ram, Dodge, Jeep, and Cadillac applications. From Silverado and Sierra HD diesels to Super Duty, Ram HD, Wrangler, and Escalade platforms, Mishimoto continues to expand its catalog with bolt-on upgrades that deliver measurable performance gains.
