Rockauto has the csf one 78 bucks it's thicker than oem 1 5/8. The stock one in my 01 RT is 1 inch thick and it's been fine for 18 years and just started leaking, i ordered the Mopar heavy duty because i use it to tow. I measured it today and was shocked that it was only 1 inch. The other Durango rt i have has the heavy duty radiator for towing and that one 1 1/2.

Being dimensionally the same, the only thing "heavy duty" about the mopar one is it probably has extra fins for the heat spreader between rows.

In every installation there is an optimum combination of fin performance and core restriction that will produce maximum heat transfer. Increasing the core restriction from this optimum point by increasing fin count will reduce the heat transfer performance of the radiator. On the other hand, if the original radiator has a very low fin count, increasing will improve heat transfer. In general, for high performance applications, fin counts from 12 fins per inch to 16 fins per inch are optimum. Increasing the fin count above 16 fins per inch will almost always result in reduced heat transfer performance.
