Simply Awesome
Folks, this product is just plain amazing. There is no ifs, ands, or buts about that. Installation was simply a breeze compared to what I thought it would be. Instructions are very clear. All watertight connectors on the harness. PLENTY of harness length, installed on a 2013 Ram 1500 Crew Cab and had almost 5 feet to spare! THAT NEVER HAPPENS WITH PRE-MADE HARNESSES!!!! Kit came with extra airline T's, and everything you could possibly need. I had an entire bag of leftovers. Now please note that this kit is not made for coil spring vehicles, which is what I installed it on........ Wait, how did you do that? The ONLY reason this product is not recommended for coil spring vehicles is that normal airbags for coil spring vehicles will either replace, or fit inside of the existing coils. This kit is not made to adjust for those types of bags. Also, the bracket for the magnetic height sensor is made for leaf springs. I modified it and put it where I wanted it, and it works fine. The magnetic height sensor is EXTREMELY touchy. For example, I get out of the truck, leave it running, after the built in delay period it will open the air release solenoid for a split second and lower my truck the quarter of an inch it just rose from me getting out. Likewise, I hook up a trailer, it kicks on and raises the truck right back to the set level. Simply perfect!! The ONLY thing I would add is the ability to manually overide the automatic system (i.e. on/off switch), but that can be added very easily at any time. As sold, this kit is just great. I've had it installed for a month with no issues at all. I could not possibly be happier with this product or with how fast Suspension Connection got it to me. Top notch quality, top notch price, top notch shipping. How do you beat that folks? You Dont!!!!
