      Description

      Heavy-Duty Hardware. The PPE Up-Pipe Bolt Set delivers robust clamping force and durable service for high-heat, high-vibration exhaust connections. Engineered as a direct replacement with OE-comparable geometry, these fasteners are purpose-built to keep joints tight and leak-resistant under demanding conditions. Full fitment: fits 2017-2026 6.6L Duramax GMC Sierra 3500 HD models.

      Construction and Appearance. Each fastener uses high-strength steel rated at 220+ KSI tensile strength to maintain preload through heat cycles and vibration. Precision M8-1.25 threads and a 30mm underhead length provide reliable engagement in factory components, while the 12-point bolt head promotes even tool contact for confident service. A matte black finish offers added surface protection and a clean, professional look that resists corrosion and grime between maintenance intervals.

      Installation. These bolts are designed for straightforward, bolt-on use with factory up-pipe and flange hardware. The 12-point head simplifies tool access in tight spaces, supporting consistent torquing and clamp load across the sealing surfaces. For best results, clean mating threads, chase if necessary, and apply the appropriate anti-seize or thread treatment specified by your service procedure; torque in a crisscross pattern to establish an even seal and recheck after initial heat cycles.

      Warranty. The PPE Up-Pipe Bolt Set is backed by a limited 1-year warranty, providing assurance against defects in materials and workmanship. This coverage underscores the fasteners’ durable construction and gives confidence that the joint integrity will remain stable through regular temperature swings and mileage.

      Application. This PPE Up-Pipe Bolt Set fits 2017-2026 6.6L Duramax GMC Sierra 3500 HD models. By replacing fatigued or corroded hardware, it helps maintain gasket crush, reduces the chance of exhaust leaks, and supports consistent sensor readings—contributing to smoother operation and easier future service.
