Kill Exhaust Leaks Before They Kill Your Turbo Response.

Duramax up-pipe bolts are single-use by design — stretched, heat-cycled, and seized by the time you're back in there. This complete 12-piece high-strength bolt set lets you reseal both up-pipes properly instead of reusing fatigued factory hardware that leaks and ticks under boost.

  • Complete 12-piece set — services both up-pipes
  • High-strength 12-point bolts resist stretching and heat fatigue
  • Direct replacement for factory hardware (replaces 116121500)
  • Fits 2001-2016 Chevrolet Silverado / GMC Sierra 2500/3500 6.6L Duramax (LB7, LLY, LBZ, LMM, LML)
