Full air ride VS coilovers

[Isobaric]

Would you mind telling me why peterbilt now has air ride all the way around? Or does this only apply to lifted pickups with improperly setup 4 link?

Why? Weight savings and driver comfort are the primary two.

How? Those systems were designed from the ground up to utilize an airbag along with a traditional taper-leaf. The daily engineering budget of PACCAR, Dana, Hendrickson, etc, is more than the yearly operating budget of all light duty aftermarket suspension companies combined.

Because they have millions and millions into designing them. They have trucks now days that can go down the road without anyone driving it. Giant test tracks specifically built to challenge and put them in every environment possible. It is a huge industry.

It's also easier to design and build a system with limited movement. Big trucks aren't trying to have 16" of wheel travel so it's much easier to keep the bad aspects in check.

Best post to date.
How is your kit on the concrete settling lines on highways? (The ones that kill you in a stock truck)

I have not found a road yet that I didn't like... We don't have many roads around here that have those expansion joints like you are talking about.

Funny thing is I took a truck with essentially the same kit as mine down to California. It is a 575 series with 3.0 coilovers and 3.0 bypasses all the way around. Drove awesome and I don't remember the roads ever bothering me. But what I did remember is getting in the rental car on the way home and noticing how ****ing ****ty the roads were on the way back....LOL. Didn't realize how great the truck road until I got into the rental. LOL

That is one real cool deal about the bypasses though. If I did find a ****ty road. It doesn't take much time to get out and tweak all the bypasses one way or the other... That works for offroad too. You can open up all the shocks and drive the dunes or the whoops.... or whatever...then adjust all the bypasses back to your normal settings and drive home. But you got to know what the heck you are doing in the beginning when you are valving the system. The valving in the coilovers is so much different than the valving in the bypasses.

Valving Is done already by sage carli. I just need to fine tune to what seems the be the rear shock which has bypasses. Do I mess with the mini compression tube or the long one?

Got any pics of the shocks?

You just got to play with them. Are they 2-tube or 3 tube with compression and rebound bypasses?

I usually start from one extreme and go to another using large changes and driving over and over the same spot...LOL
