THE HEAVY HAULER SERIES THE ROCK CRAWLER AND MUD CRAWLER SERIES
Our Heavy Hauler series is built for one thing: Pulling. Whether it's pulling the boat, the camper, the RV, or the horse trailer, this is a work transmission with special attention paid to cooling and maximum torque handling while still retaining reasonable shift comfort and drivability. If you have a truck that works hard, these are the transmissions built just for you. They are available in GM 700R4, 4L60E/65 and 4L80E. Click below to learn more. Our Rock Crawler and Mud Crawler Series is very similar to our Heavy Hauler, except it's built with climbing and spinning in mind. It has slightly more aggressive shifts and more punch built in. It is ready to head to the mountains or play in the bog - your choice. It's available in GM 4L60E/65, 700R4 and 4L80E. Click below to learn more.
