Interstate Transmission & GTK Services LLC, 695 Industrial Blvd, New Richmond, WI 54017, US

HistoryTri Star is a family owned and operated business that was founded in 1988 by Dave and Judy Steine. Dave had been rebuilding engines and working at wholesale auto parts companies his entire life and finally decided to turn his passion into his own business. A lot of 'About Us' pages will tell you they started with a wrench and garage, but Dave went in head first with a huge loan for a 40,000 square foot building and the drive to work harder than anyone else. That ambition to take risks is what pushes us to constantly improve and innovate; if there's a new piece of a machinery available to increase the quality of our engines we buy it, if there's a way we can better serve our customers we implement it. One thing that has never changed in the 25+ year history of Tri Star Engines is our family owned values. It seems like a simple philosophy Treat people right. That's it... We've given away the secret to our success. We treat every customer right!SpecialtiesWe design and build engines for all types of OE replacement, racing, performance, diesel engines and marine applications. We also sell transmissions, transfer cases and differentials. Focused on providing high quality American made products backed up by multiple full coverage warranty options.
