I wish there was a selectable locker that didn't use clutches and was normally limited slip and full locker when locked up. I know auburn makes a selectable locker that is limited slip/ locked but it uses the clutch packs....and I believe it may only be made for smaller axles, I can't recall.

You probably could have just pulled 2 of the front shocks and kept them as spares or for another project. that's what I did when I got a PMF dual stabilizer kit with fox steering stabilizers/ dampers. It was so stiff that the wheel would not recenter and it was a pain. you could literally drive down the road and turn the wheel a hair and it would hold that position. so I pulled the kit and made it work with the factory setup. Although, I think 1 Fox is still slightly too stiff..

 

Shocks are tunable and Fox (like any full line shock manufacturer) has several offerings and will even offer custom tuning for a given shop that's putting together kits. Shock tuning is normally done via a combination of valving and oil weight (and nitrogen pressure if applicable). PMF probably just spec'd a damper that was to stiff for your application.

PMF is a more hardcore off-road type shop, like they expect their stuff to be use /abused. So they probably spec'd a stiff shock assuming it was going on something with 42+ inch tires that was competing in King of Hammers (which has an open desert racing section between rock crawling trails). BDS on the other hand (the makers of the dual steering stabilizer kit I have on the Excursion) , well, they're a little less hardcore, and know full well that at least half of their customers vehicles will never see actual off road use. Sure their stuff is still capable, but they offer some compromises for on-road comfort/ on road usability that shops like PMF just don't.

I have three different styles of Fox steering dampers in my current little fleet of vehicles. The excursion has the BDS dual kit pictured on the first page of this thread. The 2010 F250 has a weird double ended thing with a through shaft Fox stabilizer pictured directly below (that kit was from CJC offroad). And the Dodge has a custom /homemade setup using a fox IFP (internal floating piston) damper that's popular for Jeeps with one ton axle swaps (second pic below). I hated everything about the stock Dodge steering setup BTW, what's seen below is a Frankenstein conglomeration of crap I threw together from various year trucks to make it suck less.

All three return to center just fine, and drive like you'd expect any normal vehicle to, heck the 2010 F250 is even my teenage son's daily driver, no way would I give him a vehicle with weird handling characteristics.

My actual Fox suspension shocks are supposedly tuned for my particular truck which were purchased from PMF. I've been happy with those...you're probably right on the dampers though...probably for a rock buggy that hasn't gone to hydraulic steering
My Fox damper literally is the size of a 2.0 shock...like 3 times larger than oem or the KYB I once used. I used to have a bilstein damper but I gave that to a buddy one time when I put my truck back to stock suspension. That damper was fine.

My truck drives/ handles well with no effort, it just doesn't fully recenter like it once did. The way i have my front end lifted might have a slight role in that as well. I would have to pull the fox damper off to see. I'd just like it to recenter better but have adapted to it. It's not unsafe in any way, just not ideal either

 

Just make it simple and easy to repair with OEM parts

 

I’m guessing that truck bump steers like a big dog with how not parallel the track bar and drag link angles are.

Looks like this was the fresh build picture because all the paint is new and clean. Has a track bar drop bracket been put on since to help reduce the bump steer?
…

 

Drop pitman arm with stock track bar bracket?
I guess dual stabilizers are useful in at least this case.




just messin round bros. carry on.

 

That's an 08+ front end based on how the drag link connects to the knuckle and tie rod, so there is no telling what the mix of stock to aftermarket parts are, but with the drag link and track bar being at that much of a different in angle, there is no way that truck doesn't bump steer, even with the dual steering shocks.

For that truck to not bump steer the way its pictured, the suspension would have to literally not compress or extend, ever (which if its street queen / bro-dozer, that might not be a problem).

I thought all the '05 & up D60s were like that, mine came out of an '06 F350 anyway. Maybe the leaf-sprung D60s still had the cursed y link for clearance? I can't say for sure, I got mine and I'm happy so the technical history aint on my radar after that.

 

AFAIK all the leaf-sprung Ford Dana 60's had the same T- link style setup like the 4x4 Excursion's had. Yeah the drag ling connects to the tie rod and not directly to the knuckle, but the tie rod is still solid between each knuckle. Below is a pic of the Dana 60 currently in my Excursion. There is a solid tie rod going between the two knuckles and the drag link is zip tied to the tie rod so it doesn't flop around during installation (read arrow at the connection point)




A Y-link steering (like the Dodge setup I mentioned hating earlier) has the drag link going to the knuckle, but the tie rod for the other side connecting to the drag link. So the two steering knuckles are not solidly tied together. So while a Y-link setup doesn't really have bump steer, the toe number changes every time the suspension cycles, and change differently side to side for a given amount of suspension travel. Below is a google image search pic of what a Y-link setup looks like. This is what my Dodge (and my old Jeep XJ ) had in stock form. They have their advantages and disadvantages, didn't hate it on the little light Jeep XJ, but hated it on the heavy Dodge Cummins truck (hence why I converted the Dodge to a T-link setup from a later year truck with an HD steering option).
