Our technicians work on all major heavy-duty makes, including Freightliner, Peterbilt, Kenworth, Volvo, Mack and International, and get approval from the driver or fleet manager before any repair begins.

Customer Reviews
What Drivers & Fleets Say
“We use Rapid Truck Repair regularly for road calls, and I honestly don't know what we'd do without them sometimes. They've saved us more headaches than I can count and have proven time and time again that they're people we can count on. They do great work, they're honest, and they genuinely care about taking care of their customers. A huge shoutout to Macie! She's always incredibly helpful, easy to communicate with, and willing to go the extra mile.”
“I've been in the trucking industry for many years, and this is by far the best truck service I've ever received. They were quick to respond and handled everything efficiently. On top of that, their pricing was extremely reasonable which is a huge relief when you're in a bind. I'm definitely sticking with them for any future truck service needs. Highly recommend!”
“I've had Rapid Truck Repair help me out a couple of times during the night with our semi-trucks, and they've always been on time. We broke down in Weed, CA and they went out of their way next day to make sure we had the right parts to get our truck fixed, which was super important for keeping our deliveries on schedule. Really appreciate their quick and reliable service.”
“My EGR pipe completely cracked off on my T680 with an X15 engine. I was in Yreka, California, and it was the weekend. They came out, removed my parts, went to the Kenworth dealer, picked up all the original hoses and clamps, completed the repairs, and got me home. Can't thank them enough!”
