Peterbilt 587 CAC Clamps, Boots & Hoses

Get the Right Fit for Your Big Rig

If your Peterbilt 587 feels slow to respond or struggles to hold boost, the CAC system is often the cause. CAC clamps, boots, and hoses carry cooled, pressurized air from the turbo to the engine. When they seal tight, your truck runs cleaner and pulls harder. A leaking CAC boot costs power. Acceleration drops. Hill pulls suffer. Fuel use climbs just to stay at speed. That poor air balance creates soot, which loads the DPF and raises the risk of a derate. Oil shortens boot life. Turbo oil mist softens silicone over time. Boots swell and lose shape. Under boost, they split without warning. Replacing oil-soaked boots early helps avoid roadside breakdowns. Clamps are just as important. Weak clamps let hoses shift under pressure. That causes leaks and can pull dirty air into the intake. Grit inside the engine leads to permanent damage. Heavy-duty CAC clamps keep connections sealed.
