By doing so, you can ensure that your truck receives timely attention and avoid any unnecessary downtime. Call (916) 571-8888 to schedule.
We’re a repair shop, not a rental fleet — we don’t have loaner trucks. What we will do is tell you honestly how long the truck will be down before work starts, so you can plan the load board around it.
Payment is due on completion of the work — there are no net terms, billing accounts or payment plans. Call the shop at (916) 571-8888 to confirm which payment methods are accepted before your visit.
The frequency of maintenance checks depends on several factors, including the make and model of your truck, its age, and the type of usage it undergoes. As a general rule, at Pro Truck Services, we recommend bringing your truck in for a comprehensive maintenance check at least once every six months or as specified by the manufacturer’s guidelines. During these checks, our technicians will perform a thorough inspection of your truck’s key components, including brakes, tires, fluid levels, belts, hoses, and electrical systems. We will also perform necessary services such as oil changes, filter replacements, and lubrication to keep your truck running at its best.
