Exact fit, exact fix!
I had an issue with my IWEs engaging / disengaging half way and causing a ratcheting sound. I replaced the IWEs and when I did that, noticed water in them and in the hoses. The original hoses were heavily cracked and not supplying a solid vacuum. Since I went through the trouble of replacing the IWEs I figured a new set of hoses couldn't hurt. These lines were identical to the factory (actually had a few more heat shields), fit perfectly and were simple to install. I've had no more issues with noise from the IWEs. In fact, fixing the system has actually saved me money. My fuel mileage has improved in 2WD because the front axel shafts aren't rotating anymore until I engage 4WD (which is almost never). The way Ford designed the system to function. Definitely worth the money.

Good quality
Great price. Arrived quickly. Very good quality. Unfortunately, I have not installed yet due to a heat wave in southern Idaho. I finally installed these vacuum lines in my truck around the end of July 2025. They worked great. They fixed the problem of low vacuum at my IWE's on My 2007 Ford F-150. Now my IWE's do not make the grinding sound. Thank you, Don

DYI solution with professional results.
Helped get all my vacuum leaks sealed up so my new activators work. Replacing with complete set makes it much easier than Jerry rigging stuff together and taking chances of grinding axles inside bearing assemblies. Now 4x4 when I need it and saving $ when I don't.
