I’m going to check it out, thanks!

 

We have a few users who have done the retrofit.... some examples are @chewblekka & @muffin86 off the top of my head. These are serious DIYers, so if you're looking for a shop to have it done at, you'll struggle, plus you won't like the $10k+ cost that will come with it.

 

A struggle indeed… I appreciate the post! Definitely not worth having done professionally at that price. Plus I’ve had the thought that due to the unique vehicle not many people have experience working on it anyways, and especially not for a job like this one. For those that DIY, do you have any insight on what suspension products they installed themselves?

 

They used the OEM system\parts\controllers.

 

 

All OEM parts! The Air Suspensions I bought were used but came off a Porsche that had the same part numbers. Hardest part to find are the air lines in my opinion, the rest is quite easy to find.

 

My guy, I can 100% understand wanting the immense benefits of air suspension for a host of reasons. But, to justify a measly 574lb tongue weight? That's quite a stretch.

This is over 1,000lb tongue weight. Angle of the driveway exacerbates the perception of squat. I don't think you should worry about the piss in a bucket 574lb squat unless you're planning on loading the heck out of the town vehicle
