drop zone has a full warrenty lifetime on the product, and 30,000mile blowout, i have been riding on them for 1000's of miles, at fast speeds over bumps sharp turns, with exceeded weight and they still ride the same as the day i put them on. i dont know why everyone disses dropzone struts, how did they get a bad name, they are inexpensive but that doesnt say that they are bad, honda's are inexpensive cars and in my opinion the best cars on the market with the best engineering. i love my dropzones, yea there are better than dropzones of course, but there is nothing wrong with these struts. i have had, blues and oems other than my dropzone, i have had ground controls, shitty coilovers, and my prokit that i have now. my ride with prokit and dropzones is great,i would like to get a little stiffer spring rate, but i am very satisfited with my dropzones, more than Tokico blues, and oem.
