I replaced my stock fronts with the Arnott units that come with a resistor so you dont trigger a warning light. I've noticed no ride difference-still rides great. I replaced my rears along with a compressor also from Arnott-I bought the re-manufactured OEM ones because they were plug and play. I also tow and like the auto level feature. It is true that the autoride as a whole can be problematic but when that time comes I will probably just replace the entire system with a passive one w resistors. But in the meantime-no complaints.....
