2004-2010 Chevy GMC 6.6L Duramax LLY LBZ LMM PCV/CCV Reroute Kit

Precision-engineered from high-grade aluminum alloy with a sleek, black-anodized finish for superior corrosion resistance and lasting durability.

Enables a clean reroute of restrictive factory ventilation lines, effectively eliminating oily residue deposits within the engine’s crankcase vent system.

Features heavy-duty 5/8" CCV/fuel-rated hose—upgrading from standard heater hose material to ensure maximum heat resistance and longevity.

Dramatically improves ventilation flow and prevents oil-laden vapors from entering your turbocharger, thereby reducing intake soot accumulation.

Streamlines your engine bay by moving bulky factory lines, freeing up essential space for other under-hood maintenance or performance modifications.

Designed to promote a healthier, cleaner engine environment by optimizing crankcase pressure management.

Fits: 2004-2010 Chevy Silverado and GMC Sierra 2500HD / 3500HD 6.6L Duramax (LLY / LBZ / LMM engines).
