ECE uses their own part number, but when I called I was told they use the same shocks for 2/4 all the way to 4/6 drops. I did alot of research and I ordered my KYB shocks from Summitt as they had the best price. I went with 344055 for the rear ($27.31 each) and 344068 on the front ($23.06 each). I am very happy. I cut 1 front coil and used Jeep TJ springs in the rear. I also relocated my rear shocks. Rides 10x better. Summitt will tell you the 344055 is for the rear of a Nissian Quest van but it is KYB part number that ECE sells with their own part number. I hope this helps.
