CAC & Radiator Tubes

Swapping a Caterpillar, Cummins, or Detroit Series 60 engine often means the turbo outlet, intercooler, and radiator ports no longer align with your truck's factory routing—making off-the-shelf tubes a poor fit. Kustom Truck Parts offers precision-engineered CAC tubes (charge air cooler) and radiator tubes built specifically for heavy-duty engine conversions on chassis like Kenworth, Peterbilt, Freightliner, and Western Star.

Our lineup includes:

  • Individual pipes (e.g., left/right side CAC, upper/lower radiator) for targeted routing
  • Full piping kits (RAD + CAC) for complete airflow and coolant integration
  • Intake elbow kits for Caterpillar engines (engine-mounted or external air cleaners)
  • Hump hoses, installation kits, and even custom kits built per your specs

Crafted from durable stainless steel (offered in mill or polished finishes), these tubes ensure proper fit, efficient boost/coolant flow, corrosion resistance, and reliable performance in demanding swaps—without custom fabrication hassles. Ideal for mechanics and owner-operators tackling repowers or engine conversion projects.
