Peterbilt 387 CAC Clamps, Boots & Hoses

Upgrade to Premium Silicone CAC Boots: Engineered for Extreme Heat

Our lineup of replacement CAC boots and hoses can help get your CAC system back on track. A cracked boot or weak clamp leaks boost. You feel slower throttle response, softer pulls on grades, and higher fuel burn just to keep speed. That poor air balance also creates extra soot, which loads the DPF faster and increases the risk of a derate. One small leak can turn into lost time and money. Oil exposure causes most CAC boot failures. Turbo oil mist slowly breaks down silicone. Boots soften, swell, and lose their shape. Under heavy throttle, they split without warning. Replacing oil-soaked boots early helps prevent blown hoses and roadside breakdowns. Clamps matter just as much as the boots and hoses. Stretched or low-quality clamps let hoses shift under boost. That leads to leaks and can allow dirty air to get pulled into the intake. Dust and grit inside the engine cause permanent damage. Heavy-duty CAC clamps keep connections tight and the airflow clean.

Failure Warning Signs

You may hear a sharp hiss or whistle under load. You may see oil residue on boots or black smoke on acceleration. You may notice lower boost readings on the dash. Replacing CAC clamps, boots, and hoses is a smart preventative repair. A quick shop install beats a blown boot and a tow call. This lineup of Peterbilt 387 CAC clamps, boots, and hoses is built for long-term, heavy-duty use
