Mack Repair & Service

Vocational trucks, mixers and dump chassis

Mack chassis in this region are heavily vocational — mixers and dumps that spend their life loaded and off pavement. The frame and body take the punishment before the driveline does.

What we see most on Mack

  • Dump body and hoist structural repair
  • Frame crack repair on loaded vocational chassis
  • Hydraulic hoist cylinder rebuilds
  • Suspension and mounting bracket welding
