Stroppe Edition Rear Sway Bar Question

[ThunderFlash]

I was a little surprised to see the Stroppe, being a 2 door, comes with a rear sway bar. Is that unique to the Stroppe, part of the current SAS package, part of the HOSS 3.0, or do current BLs have it too? Is it the same part/stiffness as a 4 door sway bar? Anyone know the part number for that Stroppe bar, if it's different from a 4 door bar?
My '22 2 door WT was a HOSS 2.0 rig. I don't know I need it just yet, but I might after I put my doors, roof, and roof rack back on the truck. In July, I swapped the standard rear Eibach springs out for the HD springs (already had HD springs in the front). It helped the sloppy body motion significantly, but haven't yet put it back into fall/winter mode yet. Putting that high weight back on, then some load on the rack, could bring back that sloppy feeling. I suspect this bar could cure that should it be an issue.

Thanks for the help!

Part of the HOSS 3.0 Suspension.

@Ducati1098 might be able to find the part number.

Thanks @Beach_Bum! I've looked at all the Bronco option packages a million times and never noticed the rear bar in the 3.0 package.

@Ducati1098, I'd be curious if the 2 door HOSS 3.0 P/N is different from a 4 door SAS 2.0 P/N and a 4 door HOSS 3.0 P/N. If it is, I might have to go crawl around dealer lots with my calipers and measure the bar diameters. If I add a bar, I think I'd want the softest option.....with out paying a freaking grand for the Rock Jock. It's sporty, but it's still a just a sway bar, IMHO.

It’s the same on all broncos equipped with one.

Bar is NB3Z-5A772-A
Links are NB3Z-5C486-B

@Beach_Bum and @Ducati1098, thanks a ton. It would have taken me a long time to figure that out...and then I'd still question myself. Good news they are all the same. I may have to visit some local salvage yards. Got to be some crashed 4 door SAS around.

The oem rear sway bar is 17 mm diameter.

if increased front articulation is the goal and still having some lateral sway resistance on the road. Then having a reasonably sized rear bar and decreasing the front bar diameter is beneficial. Oem front bar is 1 3/8” diameter. Many aftermarket front bars are just under an inch diameter (7/8” range). Rockjock and Carli.

small changes in bar diameter result in large changes in torsional resistance, a function of the diameter to the fourth power.

Thanks Z. Increased front articulation wasn't the goal....but it would be nice to get more. I've watched that video with the Toyota guy, and its interesting that stiffing the rear up forced more articulation to the front for better total articulation front and rear...if that makes sense.
It's a long story, but my truck has become a bit of a piglet. She's probably +350 pounds or more on the hoof and unladen. Most of that is on the front axle, so I tried the Eibach Pro Truck Stage 2 with HD springs front, standard spring rear. I had more pronounced side to side body motion with rear squat/jacking than with the stock Bilsteins. Adding the TrailRax TRMR rack + Pak Rax made it even more wallowy on the road and trails. Running sans doors/roof/rack was better, but it just did not feel right front to back under braking, acceleration, or whoops.
A few weeks ago, I swapped out the standard rear springs for the Eibach HD springs and it was a significant improvement in just about every way, but I still have not put the doors/roof/rack back on the rig as of yet. I also want to get a 83L Roam box for the rack, which will raise the cg even higher. I'm anticipating the excessive side to side body motion may come back. So, I'm trying to be a little proactive on a plan.

I'm not a hard core rock crawler or anything. Mainly exploring ORV trails to date trying to build skills, learn the truck, and testing set ups. So far, I'm very happy with how it performs with the HD springs and a couple hundred pounds load+passengers. 17mm for the OEM bar seems a little wimpy, but it's way stiffer than no bar! I'll probably give that a try if I can do it on the cheap, like <$300 for salvage parts. Do you think that's a reasonable approach? If I get a wee bit more front articulation, too, that will be gravy!

@87-Z28, I got some lift, probably close to 2" with the Eibachs at their lowest position. Do you think I'd benefit from longer than OEM end links?

 

[87-Z28]

For now I would just add the oem rear bar and see what you think. Reevaluate the front bar after you have tested things out a bit.

I have an oem rear bar I was going to put on in the next few weeks. I only have about 1” of lift on 6100 bilsteins. Not sure about the end links for 2” of lift but I suspect they will be fine. I will know more after I mount my bar.

I found the sway bar at one place online for $132....and for $139 more, they will even ship it to me. Good golly, at least it would be a ginormous box.

I have added an oem rear sway bar and have a couple inches of lift. In some situations the rear links are definitely too tight. A while back I was trying to source longer links that would work but came up empty handed. All of the links I tried didn't quite have the right size bolt for the OEM setup. Or they were cheap aftermarket with little to no movement. My main concern is that I may break a link off road someday.

Thanks for the feed back. At least you wouldn't be stranded. What's your overall impression?

I have the Eibachs and they are pretty softly valved and sprung, even with the HD springs. I think it will benefit from the sway bar when it's back to full weight, much like Ford thought it was appropriate for the 2 door Fox set up.

 

[GI_Jo_Nathan]

Yep very true.
I've really like it with the rear bar. Feels a lot more confident driving on the road , and surprisingly slightly less nosedive. I have the factory non-sas Badlands struts and springs, and 1" perch collars added to the front.

When I'm off road I run with the front disconnected a lot of the time. Normal sway bar, so manually disconnecting the links. It adds some flexibility without being completely floppy. I don't have much added weight and what I do have is down low.

I definitely hate that I feel the rear is more limited than it should be with the links, but also on the two-door especially if you free it up too much you can get into the rear of the fuel tanks skid anyways.

For the money I think it's a great addition. Not sure about now, but they used to be really reasonable directly from ford. You just have to order each piece separately.
