Use the XDP X-TRA Cool Direct-Fit Replacement Radiator XD297 to upgrade the failed radiator in your 2006-2010 GM 6.6L Duramax LBZ and LMM. The X-TRA Cool Radiators are built for increased durability over your factory radiator. Using construction techniques borrowed from the HD and semi-truck industry, X-TRA Cool Radiators give you a long-lasting direct-fit upgrade to protect your engine and cooling system.
High-Efficiency Core Design
With more fins per inch, and heavy duty tubes to increase cooling efficiency, the upgraded core design allows you to maximize cooling potential of your Duramax.
Internally Reinforced
Using a special aluminum brazing technique, the X-TRA Cool Radiators are built for increased strength. The internally reinforced end tubes and outside corners provide more strength where the core is most vulnerable.
Gasket Design
A common failure point in many OE radiators, X-TRA Cool Radiators use a proprietary gasket that allows for contraction, expansion, and front-end movement.
Revised End Tanks
Using a fiber reinforced plastic mix adds strength to the end tanks. Reinforcement ribs are added to the weak points to help eliminate end tank failures.
Upgraded Mounting Points
The integrated mounting points have been updated for added strength. This allows for the radiator to be securely mounted in the factory locations.
End Tank/Core Assembly
X-TRA Cool Radiators use a heavy gauge steel crimp strip to mate the core to the end tanks. Instead of using aluminum like the factory radiator, the heavy gauge steel helps to eliminate the common failures of tank and core separation.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
