Our services


Did you know that the HD industry was transformed 40 years ago by Minimizer, with the revolutionary invention of its poly fenders? Famous for their lightweight yet durable design, they’ve become a must-have for road professionals around the world.

TransDiff JDH Peterbilt is proud to offer these professional-grade fenders for your truck fleet. Combine them with our brackets to create the perfect flex system, which has been tested and tortured to ensure it stands up to the harshest conditions. Minimizer offers fenders for virtually all wheels on Class 6, 7 or 8 trucks, as well as most trailers. They provide unrivalled durability, won’t crack under stress, won’t rust, and will retain their shape after a hard impact.

Mobile service

Your truck broke down on the road? Our mobile units are available during the same opening hours as the workshop to help you out. Our technicians can respond to several of your requests.

SAAQ agent

Our Lévis location is authorized to perform heavy road vehicle checks for the Société de l’assurance automobile du Québec (SAAQ). We therefore carry out mechanical checks on all vehicles with a GVWR of 4,500 kg or more; these are usually trailers (enclosed, flat bed, hand-crafted, etc.), trucks and buses. Inspections are performed in the workshop by our trained staff. Don’t hesitate to contact us if you have any questions or to make an appointment.
