Product Details & Specifications
This is the strongest DD15 cylinder head bolt set on the market. These bolts are both manufactured and treated here in the USA.
What makes cryogenic treating so special?
IPD is the first company to offer cryo-treated head bolts for the DD15. Cryogenic heat treatment is a precisely engineered process of taking materials down to approximately -310?? F, keeping them at that temperature in liquid nitrogen to remove residual stresses, and then ramping temperature back to room temperature, followed by a mild heat treatment process. The result is a considerably longer life bolt with less internal stress and optimized tensile strength. IPDs cryo-treated DD15 head bolts are designed to ensure proper and even clamping forces across your cylinder head and keep your engine running.
These bolts do not stretch and do not require retorquing. They work for all DD15 applications.
Each bolt is packaged in its own protective netting to prevent abrasions during transit.
- The bolts are the highest grade steel forged bolt in ISO classification, ISO12.9
- These bolt have rolled threads for smoother threading into the cylinder block.
- Cryogenic heat treating the bolt minimizes internal stress from the forging process.
- Cryogenic heat treating the head bolt optimizes its tensile strength.
- The rate at which the bolt fatigues is greatly reduced by the cryogenic heat treating process.
- They retain their tightness much longer than an unfrozen bolt.
IPD provides engine rebuilders with a full range of quality engine line products that range from steel pistons to overhaul kits for diesel and spark-ignited engines, and everything else you need to increase your equipments performance. This new head bolt kit offering is just an extension of their unparalleled quality and innovation.
