Peterbilt 567/579 CAC Clamps, Boots & Hoses

Upgrade Your Air Intake System with New CAC Clamps, Boots or Hoses

If your Peterbilt 567 or 579 won’t hold boost, start with the CAC system. CAC clamps, boots, and hoses move cooled, pressurized air from the turbo to the engine. When they seal tight, your truck runs strong and efficient. A leaking CAC boot dumps boost fast. Power drops. Throttle response slows. Fuel burn climbs just to keep speed. That poor air balance creates soot, which loads the DPF and increases the risk of a derate. Oil is the biggest threat to CAC boots. Turbo oil mist softens silicone over time. Boots swell. They lose shape. Then they blow under load. Replacing oil-soaked boots early prevents roadside breakdowns. Clamps matter. Weak clamps let hoses shift under boost. That causes leaks and can pull dirty air into the intake. Grit inside the engine causes permanent damage. Heavy-duty CAC clamps keep everything locked in place.
