This premium L5P/L5D Exhaust Up Pipe Stud Kit delivers unmatched strength, durability, and reliability. Designed as a superior replacement for weak, corroded, or seized factory hardware, this kit features precision-machined studs and 12-point nuts crafted from S220 material, delivering top-tier performance where it matters most.

Built to handle the extreme heat cycles and vibration found in diesel exhaust systems, each stud carries a tensile strength rating of 220,000 PSI, making them significantly stronger than OEM hardware. This ensures a secure, long-lasting seal at the up-pipe connection—critical for maintaining exhaust flow, turbo efficiency, and overall engine performance.

All components are made in the USA by Point 1, guaranteeing consistent quality and craftsmanship. Whether you’re a professional diesel shop, a performance builder, or a Duramax enthusiast working in the garage, these studs provide reliable clamping force and future serviceability.
