The staff of SoDak Diesel was able to attend dealer training days. We had a great time learning more about current available products along with some very exciting new products that are being developed and soon to be released. The comrodery and networking with other shops and dealers was great. Of course the hospitality of ATS is bar non the best around.

The wait is finally over! Fleece Performance Engineering has done it once again by developing the best drop in replacement turbo for the 17+ L5P Duramax platform.

This has been in development for a few years now and SoDak Diesel had the amazing opportunity to help with testing these units during the development stages.
