Transmission Upgrade Kits

Upgrading the transmission in your diesel rig can be a very costly upgrade and one that needs to be done right the first time.  In the world of performance upgrades, this can be the most expensive thing you do short of engine work.  Take your time, get educated and choose the best option for you.  First, be honest with yourself on what your going to do with the truck.  Do you simply use the truck to tow?   If your using the truck as a tow rig, plow truck or commuter transportation, our MA450 kit maybe right for you.   Looking to do some sled pulling, drag racing, or other forms of competition use?  Got aftermarket turbo or injectors?  You should be looking at our MA700 kit.  Rated to hold 700 HP, this will hold up to the rigors of competition.    Got big twin turbos and nitrous?  You need to look at our MA1000 kit, you can throw the kitchen sink at it, it does not matter.

First, lets look at the options offered for your transmission upgrade.  I’ve gone away from all the confusing “stages” and “levels” often associated with an upgrade.  Its easy to get caught up in all of the competition of naming a transmission kit Extreme or Stage V and so on.    To make it more simple for you to decide I’ve labeled them by a conservative horsepower rating.  The MA450 kit is rated at 450 RWHP, the MA700 kit is rated at 700RWHP.  How do we get the ratings?  Real world testing, years of experience and hundreds of units built.  Lots of trial and error has been done, things have been tried that did not work, some things that do work.  I've taken the guess work out for you.

*   Ability to hold rated horsepower levels is effected on driving habits and engine and transmission calibration.  Transmissions that are abused from excessive temperature, careless or “show off” type driving may not be able to withstand rated horsepower for extended periods.  Proper engine and transmission tuning is essential to long transmission life.
