Description
The XDP Xtra Cool Direct-Fit Replacement Radiator XD295 is an upgrade for the old leaking radiator in your 2001-2005 GM 6.6L Duramax LB7 & LLY. While the Xtra Cool may resemble a stock replacement, the construction and design is far from it! The Xtra Cool Radiators are specially designed with upgraded techniques borrowed from the semi-truck and HD industry. Unlike the OEM radiator, extra steps are taken to ensure added durability and strength to protect your cooling system.
High Efficiency Core
XDP's Xtra Cool Radiators are built with a high efficiency core that has 18 fins per inch over the factory 16 fins per inch, and heavy-duty tubes to maximize cooling capabilities.
Internal Reinforcements
For added strength, special aluminum brazing techniques are used during construction. The reinforced end tubes and added strength at the outside corners protect the core where it is most vulnerable.
Gasket Design
Xtra Cool Radiators feature a proprietary rubber gasket designed to withstand expansion, contraction, and the flex in the front end of your truck.
Revised End Tanks
Reinforcement ribs are strategically added to the end tanks to strengthen weak points. The plastic mix includes a fiber reinforcement that is added during tank construction to provide more strength over the factory tanks.
Upgraded Mounting Points
To allow the Xtra Cool Radiator to stay securely mounted in the same factory location as the stock radiator, the mounting points have been upgraded for added strength and longevity.
Tank Attachment
To attach the end tanks to the core on the Xtra Cool Radiator, a heavy gauge steel crimp strip is used instead of aluminum like the factory design. The heavy duty crimp helps eliminate tank and core separation failures that many experience with the factory radiator.

- Direct-Fit Replacement

XD295 Radiator
SteveA (Lincoln, CA) | December 19th, 2025
I replaced my stock radiator after 19 years with this XD295 radiator back in 2021 while doing other upgrades on my 2002 LB7. It fit perfect with my Banks intercooler. The price was very reasonable compared to other options out there. It has been working great after 4 years with no issues.

Good pruduct

I gotta say, if Jesus himself packed a radiator, I don’t think he would have protected it as well as these guys. That package was well over double the weight of the radiator just in protection. Installed it today and all is well. Looked like it was made very well, my only gripe with it was they gave me new fitting for my transmission lines and the ones that came pre installed were all red loctited in, not a bad thing but my got was it a fight to get them apart. Overall very nice radiator

radiator install went extremely easy. Only had to swap out with the furnished shorter fittings. Radiator fit perfectly. Now only time will tell, got 19 years and 180,000 miles out of the original.

Been super happy with the radiator for Dmax's from these guys. Cross multiple generations, all fit great, and seems to be a nice upgrade to factory units.
