Premium Bolt Kit for PPE Up Pipes

If you're planning to install new up-pipes on your Duramax, don’t overlook one of the most important supporting details—your hardware. The PPE 116121500 Up-Pipes 12-Piece Bolt Set is designed specifically for 2001–2016 GM 2500HD and 3500HD trucks running the 6.6L Duramax, offering the strength, fitment, and reliability you need for a solid, worry-free seal. Whether you're replacing worn-out factory bolts or upgrading to a performance up-pipe system, this kit gives you exactly what you need to get the job done right the first time. Each bolt in this 12-piece set features an OEM-style thread pitch and comes pre-packaged with washers to ensure even torque and proper sealing. PPE went a step further by increasing the thread length to accommodate washer thickness, so you’re not sacrificing engagement like you would with standard hardware. Two of the bolts are slightly longer to support the downpipe mounting bracket, a thoughtful touch that saves time and headaches during installation.

High-Quality Construction

Built with durability in mind, this hardware holds up under the extreme heat and vibration generated by diesel exhaust systems. It’s a small upgrade that plays a big role in preventing leaks, broken bolts, and future repairs. If you're already under the hood, it's worth replacing old, rusted fasteners with a kit that’s designed to last—and designed to fit like it should.
