74-85 12A 3mm Atkins Cryogenically Treated Apex Seal Set (ARE12-3-C)

12A Cryogenically Treated Apex Seals. All of our apex seals undergo a heat treatment, these apex seals are taken one step further with a cryogenic treating process which creates a denser, more uniform grain structure that allows heat to be dissipated more quickly and uniformly. This tighter molecular structure also increases strength, wear life, and fatigue life.

 The material for these seals has been developed by David Atkins over his extensive racing career in order to exceed stock apex seal life and durability. We have customers running 7 second quarter mile times with these seals. Customers use them in a wide variety of applications including turbo, NOS, superchargers, and naturally aspirated applications.

Detonation will ruin any apex seal, none are immune from this problem. Some apex seals will bend under detonation, and become useless, due to lack of compression, these may break but they will do so inside of the rotor and save your housings. The benefit of these is that they can takes much more abuse before breaking than other seals can before bending.

Why cryogenic Treatment

Metals Last up to 600% Longer

Cryogenic processing extends the life of metal, up to 600% longer.

Save Money

Our process extends the life of your metals, which means you spend less on maintenance or repairs and keep that cash for something else.

Reduce Metal Stress and Fatigue

We freeze at-risk metals to -300°F, causing structural changes at the molecular level to make your wearable parts more resilient. This helps fight corrosion, breakage, and wear – reducing unnecessary stress on your metal parts.

TIP

** Check the rotor with a feeler gauge to ensure that the tolerance between apex seal and groove are correct. The second picture is an example of a bad rotor that needs to be replaced or milled to 3mm if not already done so.
