Max-Flow Duramax Oil Cooler Upgrade Kit

Fits 2001-2007 LB7 LLY LBZ 6.6L Duramax & 2011-2019 LML L5P 6.6L Duramax

The Max-Flow Duramax Oil Cooler Upgrade kit includes an oversized oil cooler that has improved fluid dynamics to take full advantage of the cooling plates within the oil cooler. If you are concerned with oil temps or they are getting hotter then you will benefit from this bolt on replacement oil cooler for your Duramax Diesel. When testing this oil cooler kit we have seen a 10-15 degree decrease in oil temperatures during daily driving when unloaded, we also tested this with a trailer attached and going up a fairly steep grade we saw a 25 degree drop in peak oil temperatures after installing this Max-Flow Oil Cooler Upgrade kit.
