These premium quality Arctic High Flow units are simply the best choice when its time to replace your factory or aftermarket radiator. Other Aftermarket radiators tend to fail quickly, fit poorly, and often leak immediately after installation. These radiators are manufactured to the highest quality and are reinforced in all critical areas to exceed the OEM specifications.   All Radiators are double-checked for damage before shipment and are packed with triple-wall cardboard material to ensure no damage occurs in transit. This is the only radiator Dmaxstore will install in house.
Includes:
  • Radiator
  • Fittings
  • Grommets
Replaces:
  • GM Radiator Part# 89018318

DmaxStore Note: If you are going to pull the plugs on the cooler for aftermarket lines, please start with the top one and replace it and then move to the bottom one. The cooler inside may move if both are pulled at the same time. We also recommend replacing your stock radiator anytime after 200k miles or when replacing the water pump or trans coolers.

*2 Year, Unlimited Mileage Warranty*

This radiator worked perfectly

This radiator worked perfectly, I use my lb7 to pull 12k trailer in the rocky mountains, my old oem radiator would cause the truck ect to reach 230 every time I went up Eisenhower, didn't matter how much i cleaned it out,this maxflow radiator on the same trip never made it to 210. Im very happy with it
