Since TRX Pro.15 engine mounts, starters and exhaust systems do not work with the TRX 2.5R Racing Engine, we have prepared specially priced upgrade conversion packages to allow owners to easily install the new engine. The upgrade packages contain all the items necessary for a complete factory-style conversion. Depending on the application, the packages include items such as the engine mounts, linkage, exhaust header, pipe, and other required components specific to each model. Major components come pre-assembled and pre-adjusted. Just bolt them on. These packages are an incredible deal compared to the cost and headache of trying to research and acquire the parts separately on your own for the conversion. Purchase these upgrade kits from your local dealer, they are listed on the engine exchange form.

The complete EZ-Start® 2 system including the wiring, drive
unit, and control box can be purchased as part #5270.
