Mid Perch

[Chinmasterflex]

Have you guys with mid-perch noticed a lot of front end chatter over occassional small bumps at highway speeds shen street driving?
I've haven't read or heard much about it but was a bit surprised by it the first few times after making the change.

I had read that thread at one point but I guess I had just dismissed it as some guys that couldn't handle a stiffly sprung vehicle. Maybe it's the same thing and just the extra spring preload... feels a lot like head shake on a motorcycle, it's pretty violent.

A local tire/alignment shop did mine 3 years ago for $75 including alignment. They are the go to guys in town for any 4WD upgrades, etc.

The way you describe it doesn't sound like it's just the added pre-load. The pre load adds a bit more stutter to small square edge chop than you experience on bottom perch. How many miles are on your shocks? May be in need of a rebuild.

I didn't really care for the feel of mid perch when I first went to it. I kind of felt like the truck went from a F150 to a F250, but I got used to it. I just installed Geiser Bros springs and rebuilt shocks on low perch and couldn't be happier. Same ride height as mid perch with OEM springs, but it handles the small stuff sooooo much better.

Edit: I also went from the OEM KOs to Toyo RTs when I went to mid perch so that probably also played a role in the stiffer ride.

Shocks were just rebuilt a few hundred miles ago through the exchange program so I'm pretty confident we're good there. I've only had it happen a couple of times and it only appears to happen in a narrow range of speed ~60-70 mph. Maybe it's the same as what you're calling stutter. Might have to give those progressive springs a shot if I cant find anything wrong. If that's the case, it's a bummer. I otherwise don't find mid perch to be very stiff at all.
Thanks for all the help, guys

This exchange program you speak of, is it something that carries over with the truck as a second owner? First time I'm hearing of this program. Thanks.

i dont think it matters who owns the truck. just as long as you are willing to pay the deposit and mail yours back when you are done.
