Turbo Flange Bolt Kit

Quadstar Tuning LLC

  • $9.95

Let us save you a trip to the hardware store with the perfect bolt kit for your turbo swap project. Typically, you can't re-use the factory hardware because most turbo housings require bolts unlike the stock setup which has threaded studs.  These shoulder bolts center the new turbo correctly (without slack in the holes) and allow you to get the torque needed for a complete seal.

We have tested these to fill all Quadstar Turbos, HX35, HX40, HX40WII, & H1C.  Others may fit as well but have not been verified. These are NOT compatible with stock turbos as those use mounting studs.


  • 4 black oxide flange head bolts
  • 4  black oxide flange nuts
