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.

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.
