Hello Arnott Industries. I had to write to you and share the good word with all of you at Arnott. The best thing about YOUR product is that it is much better and stronger than you say it is and the price is 4 times lower than a Lincoln Dealers price. Dealers price was $1,800, yours was $400. I have installed Arnott Industries Complete Front Air Suspension Shock Assembly for 2003-2006 Navigator on my 2006 140" Stretch Lincoln Navigator Limousine, which is a 12 passenger + the driver vehicle. I have to say that your product holds and works great with absolutely no problems, even when it is overloaded. I am very happy with my purchase and I tell everyone I know to purchase only Arnott products.
