Broke down, or due for service?
J&A Fleet brings heavy-duty truck repair and roadside assistance to you across the I-80 / I-55 corridor. We fix it on the spot when we can. When it needs the shop, we line up the tow at the best rate and handle the repair from there.
— and we tell you what it costs before we start.
Diesel and semi specialists, family-owned, certified, based right here.
- WHAT WE DO — one shop for the whole rig, roadside or in the bay:
- • Roadside assistance & breakdowns — we come to you, day or night
- • Diesel & engine repair
- • Air brakes, electrical & alternators
- • Cooling, radiator & A/C
- • Transmissions
- • Wheel alignment
- • Welding & fabrication
- • Fleet maintenance & preventive programs
WE COME TO YOU
Most repairs don’t need the shop. Our mobile techs roll to your truck — shoulder, stop, or yard — so your driver stays with the load. When the job is bigger than the roadside, we tap our network of tow companies, get you the best rate to the shop, and our crew takes it from there.
WHY DRIVERS AND FLEETS CALL US FIRST
• We find the actual problem. We diagnose to the root and fix that — no throwing parts at it.
• Straight pricing, every time. Rate, minimum, and surcharges up front. Stranded at 2 a.m. doesn’t cost extra.
• Done right the first time. Certified techs trained on big rigs.
• Family-owned and local. Founded by a diesel tech who became a fleet manager — and got tired of shops selling labor instead of fixing trucks.
