Description
The Maximizer 4x4 Transmissions bring performance to your four-wheel drive. A four-wheel drive application is especially tough on an automatic transmission, and the addition of bigger tires makes the job even harder. The Maximizer series is designed to be as tough as your truck, because they are built with the best components available and programmed to provide crisp shifts time and time again for applications ranging from 450 to 550 HP.

ABOUT US

It all started in 2018, with a simple idea: to create an online haven for automotive enthusiasts.

I wanted a place where people could find not just truck parts, but a wide array of automotive products, including overlanding gear, performance parts, car accessories, and
items for Jeep and SUV owners.

That's how Truck Part Superstore came to life.
