Parked on the shoulder just past exit 120 with coolant leaking and air hissing from the brake lines? That’s a long night – unless Bigler Boyz is on the way. Our mobile diesel units are built for jobs like this, stocked with the parts and tools to fix air leaks, forced regens, wiring gremlins, and busted U-joints right where you broke down. This isn’t “wait for a tow and sit in the shop” service.
When the fix takes more than a quick patch, we move the unit to our 40,000-square-foot shop off Dale Road in Curtin. From the tow to the teardown, it all stays in-house. Every minute saved on coordination means one thing: your semi gets back on the road that much faster.

You blow a tire near Curtin, PA, or lose electrical heading up Rockton Mountain? Of course you’re not thumbing through a directory. You’re searching “Semi Truck Repair near me” and hoping someone actually answers your call. Bigler Boyz always does. Our mobile service trucks operate like field hospitals for trucks: fully stocked with tires (LP22.5, 11R24.5, even 445s), wiring kits, and diagnostic gear that communicates directly with your ECM. We’ll meet you where you’re stuck: I-80 shoulder, tight gas station corner, or backroads near Wallaceton.
We’ve been around long enough to know downtime costs real money. That’s why we keep communication clear and repairs straightforward. Every job—big or small—runs through one coordinated process, so you’re never left guessing where your truck stands. We’ve built our reputation across Curtin County by doing the hard work right the first time.
We’ve been turning wrenches in Curtin long enough to know the difference between a quick fix and a real repair. Our shop, just off I-80, is built for big jobs: complete brake rebuilds, structural welding, axle replacements, and electrical rewiring. We don’t hand off your truck to a rotating list of unknowns. The same crew who greets you also gets their hands dirty fixing the problem.
We’ve been turning wrenches in central Pennsylvania long enough to know that every hour off the road hits your bottom line. That’s why our process is streamlined from check-in to completion. We coordinate directly with your fleet manager or insurance rep and keep updates flowing. The sooner you roll out of our lot, the sooner you’re earning again.
Our semi repair services span everything a working truck might need across Pennsylvania’s hills and interstates. We handle engines, transmissions, and suspension systems that take the brunt of the mileage. Electrical diagnostics track down sensor faults and charging issues before they cascade into bigger problems. We service AC and heating to keep cabs comfortable, replace worn brake components, and rebuild radiators and cooling systems for long-distance reliability. We also tackle the heavy fixes that keep fleets alive year-round—welding cracked frames, fabricating brackets, and replacing axle spindles that have seen too many winters. Preventive maintenance keeps rigs on a steady schedule instead of being stranded on the roadside. The work doesn’t stop until your semi is back doing what it was built for: hauling.
