1 inch rear sag

[GreyZ]

I struggle to believe that you are being realistic with the added weight. The bare top is 30 lbs more. If you have any of the additional panels or sound deadening or interior tailgate panels etc thats another 10-15 lbs. the grabber is 15 lbs more than the oem BFG (and sticking out more due to the lower offset). The raceline wheel is 5 lbs more than the standard Braptor wheel. If you still have anything in the rear cubby (mines probably got 25+ lbs of recovery gear), or a offroad jack (another 30). The OEM bumper is 40 lbs and most aftermarket rear bumpers are 80+. Heavy duty sliders can be 80+ lbs each and add a ton of rear weight.

Anything at all added into the bronco that is rearward of the front axle centerline will change rear squat.

Add all that up and 3/4" of squat sounds very reasonable. You likely need either spacers or a higher spring rate to handle the added weight.

This is with the 1” of sag.

Only items that remain in the back right now are the hard top, tire reinforcement, and the tire itself, which is 3/4” of sag. All the other weight is gone. I weighed every item and rounded up to the nearest pound.

Not springs but when I did my lift/level collars, the vehicle was dead even before I started to add a bunch of rear weight bolt on stuff, but I have offset everything in the rear with a front winch. At some point when I rebuild my shocks/struts I will change it over to hypercoils and figure out a bit heavier rear spring to get a little bit of rear height before heavy loads.

For fun since it's been sitting a couple days went and put a level on the rail. Just a tick rear less.

Bronco leveling springs and Carolina Squat are practically synonyms on this forum.

Maybe you should just replace the rear springs with aftermarket ones that restore the factory rake?

If this existed that’s exactly what I would do! I actually tried this with the 2”/2” Hyperco springs initially, but the springs were so stiff that with only 170lbs it would buck like crazy on whoops/jumps and the bronco would literally nose dive. They recommended I get the 2”/1” which is why I switched

I think their springs are having issues with the live valve.... It also sounds like they want them to look like $#@k boy trucks.

I’d install a 1” spring perch on the rear & maybe plate on your top cap
