Product Details & Specifications
This is the strongest 3406E & C15 cylinder head bolt set on the market. These bolts are both manufactured and treated here in the USA. 

What makes cryogenic treating so special?
Cryogenic heat treatment is a precisely engineered process of taking materials down to approximately -310 degrees 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 end result is a considerably longer life bolt with less internal stress and optimized tensile strength. IPDs cryo-treated C15 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 3406E and C15 applications, but are especially ideal for high torque applications like the C15 low compression conversion kit.

Each bolt is packaged in its own protective netting to prevent abrasions during transit. 

This head bolt set includes:
16 x 1241855 cryo-treated bolt
10 x 7N1961 cryo-treated bolt
26 x 5H1504 hardened washers

  • 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.
