Peterbilt 386 CAC Clamps, Boots & Hoses

Buy Oil-Resistant Silicone Boots to Maintain Your CAC System

A leaking CAC boot or loose clamp dumps boost. You notice slower acceleration, weaker hill climbs, and higher fuel use just to maintain speed. That imbalance creates excess soot, which puts added stress on the DPF and raises the risk of a derate. For a working truck, that downtime gets expensive fast. Oil contamination is one of the biggest threats to CAC boots. Turbo oil mist slowly softens silicone. Boots swell, lose shape, and eventually split under load. Replacing oil-soaked boots before they fail helps avoid blown hoses and roadside repairs. Clamps play a critical role. Weak or stretched clamps allow hoses to shift under boost. That causes leaks and can pull dirty air into the intake. Even small amounts of road grit can cause internal engine damage over time. Heavy-duty CAC clamps keep everything locked in place and the intake air clean. Most failures give warning signs. You may hear a hiss or whistle under load. You may see oil residue around boots or black smoke on acceleration. You may notice lower boost readings on the gauge. Replacing CAC clamps, boots, and hoses is a practical, preventative fix. A quick install in the shop beats sitting on the shoulder with a derated engine. This selection of Peterbilt 375 and 377 CAC clamps, boots, and hoses is built for commercial use. Designed to handle heat, vibration, and high boost, these parts restore power, protect the emissions system, and keep your truck running strong mile after mile
