Custom Truck Mounting Brackets

When swapping a Caterpillar (C12/C15/3406E), Cummins (ISX/ISM), or Detroit Series 60 engine into your heavy-duty truck, mismatched factory mounting points can complicate the install. Kustom Truck Parts solves this with precision-engineered engine conversion brackets and mounting solutions tailored for Kenworth, Peterbilt, Freightliner, and other chassis.

Our lineup includes:

  • Chassis-specific front engine mount brackets for secure alignment and reduced vibration
  • Engine-mounted or underhood air cleaner bracket kits
  • AC adapter brackets and dual V-belt kits
  • Battery hold-down kits, transmission supports, carrier bearing plates, and more

Built for demanding conversions and repowers, these brackets feature high-strength hardware (Grade 8/10.9), durable finishes (including powder-coated), and exact chassis-engine fitment to ensure proper driveline angles, minimal downtime, and long-term reliability. Unlike generic parts, each is designed specifically for engine swap scenarios.
