Why bring it to Truck Shark

We are a shop-based diesel repair facility at 7101 IL Rt 83, Long Grove, IL 60060, right on Route 83 and a few minutes from I-94. Tractor, trailer and reefer work happens in the same bays, so one visit can cover the whole rig instead of two stops at two shops.

Walk-ins are welcome. Calling ahead at (224) 327-2077 lets us reserve a bay and start sourcing parts before you arrive.
