Spring And Shock Package For Extra Weight?

[Sloth]

@B Miller

I was in a similar situation with my 22 Wildtrack after I added ~400lbs of bumper, winch, skids, rails, etc... I went with the full Dobinsons IMS kit (IMS shocks, 566/569 springs, track bar, lower arms, and Icon UCA). They offer different capacity springs matched to their height adjustable monotube shocks. Ride quality is subjective, but I've been happy with the ride and increased control over the stock SAS Bilstein setup.

This kit wasn't available when I ordered, but could be the subject of a future shock upgrade...
Dobinsons MMR kit (3 way adjustable plus height)

I limited my install to two inches up front with plans to raise once I address the 2.0 steering rack.

Thank you for all that information! Appreciate it!

I'm kinda in the same boat...
I try to travel light, but all loaded, my Bronco is down at least an inch and level.
I'd like to get that back.
A spacer lift would keep the spring rate and shocks (Bilsteins) working properly together...
A perch collar spring preload would give me back the height and keep the suspension geometry at factory specs but would the Bronco become too 'springy'?

Few things to note
-Would you rather your your bronco ride nice and smooth unloaded or loaded? We tend to help customers set up their suspension for how it will be used most often vs the few times a month/year.
-Spacer lift, although it wont mess with the shock function, you will need to be sure you have everything else modified to account for that extra extended length. Example: brake lines, sway bar links.
-Perch collar would be an option if there are no aftermarket springs to help. Those perch collars are just adding preload, which is totally fine. We could geek out and look into max preload on that spring, but we don't have that kind of data.

For Kings, we now have a new rear spring rate option for those who have a lot of accessories. Unfortunately this spring wont fit just any rear shock.

I have a Basesquatch where I’ve added steel front/rear bumpers and steel skid plates. It settled a bit, especially in front. Would BL/BD squash springs help? They are different part numbers for these trims, so assume stiffer for heavier stock weight. I don’t want to spend the money if negligible.
