I have been looking for a suspension upgrade for awhile now,and have decided on a Carli system. Kore has a good system also with almost the same spring assembly design. Both wrapped very close as to not infringe on each others patented design. Kore had to be ordered to your house,with shipping charge's are what they are today it came real close to what Carli was charging for it's front end kit upgrade spring/shocks. They also included swaybar end links in their frontend system. Kore does not. As far as the steering shock stabilizer goes the Kore stabilizer was more money. So that too went to Carli. As for the Track bar goes I did not see a part number for a 3 gen truck, so that too went to Carli too. Bilstein 5100's round out the deal this cost was the same both charging the same for front and rear shocks. Both charged the same for installation. I have decided to buy Carli's airbag system also,this is a manual inflate system or can be pumped by a onboard air compressor. If any one has this system please chime in on this thread as to what your thought's are on them,verse Firestone,Airride,and the rest. Carli's airbag system has the firestone boot's installed on their system. Location also came into play them being 20 minute's down the road.
