Up-pipe to turbocharger and up-pipe to exhaust manifold bolts for all 2001 to 2016 6.6L Duramax diesels. These M10 bolts are grade 12.9 and feature a minimum tensile strength of 170,000 psi. Like the factory hardware, these bolts utilize a 12 point head which permits higher torque loads while making the head more difficult to "round" than a standard hex head.


Up-pipe hardware should not be reused as they lose their material properties and strength characteristics as a result of heat exposure. Broken up-pipe bolts are very common on 2001 - 2016 Duramax diesels for this very reason, and reused bolts are significantly more likely to break. Bolt extraction is extremely difficult, time consuming, and often expensive, so we highly recommend they be replaced as necessary.


Each up-pipe requires a total of (6) bolts; (3) bolts connect the up-pipe to the exhaust manifold flange and (3) bolts connect the up-pipe to the turbocharger flange. Sold in sets of 6 or 12.


• Grade 12.9 alloy steel bolts

• 12 point head for increased resilience
