Bronco coilover spring specs?

[Ehucek]

Bumping an old thread to avoid creating a new one.

I have a base 2dr, 2.3L with the added weight of a front winch/mount, and OEM skid plates. Any shots in the dark which front springs (which 6G trim?) would be a good swap to level it out a bit? It makes more sense to me to swap heavier springs instead of adding front lift spacers. Here is what I’m starting with:

I'm in the same boat as you, just did the modular bumper Warn winch kit and ARB skid plates in my 2dr base 7MT, measured it dropped about 3/4"

Did you find any good solutions yet? I'd also prefer not using spacers, leaning toward just a lift kit where I'd go ~ 2" front and 1" rear to balance it back out

I ordered the Zone 1” leveling kit. Assuming it will bring me back to factory rake. Once the 1” kit was delivered, I immediately wondered if I should have opted for the 2” leveling kit. So, I understand the “lean” you’re feeling.

I recently swapped on a set of black diamond alloys (currently have the stock 265/70r17 Grabbers) but I’m replacing them with a set of 285/70r17 KO3 in a week or so. Adding the 1” level kit after that.

My concern with the 2” level kit is that I’ll then be tempted to install 285/75r17 tires. I’m not sure my 3.73 gearing would appreciate that…

Just to throw this out: I used Bilstein 5100s. Does not address spring rate, as you use your old springs, but you can select your lift and do different front and back per your liking. Cost would be around $650 for both ends if you install yourself. I did a winch first then 5100's then bumpers and didn't measure each time but it looks like I've retained most the lift even after added weight. It could be since the 5100s use snap ring placement for lift it preloads the springs and allows less settling than a spacer lift.

Some objectives to achieve with a suspension modification may be, in no particular order;

1) clearance at ride height
2) mid shock stroke at ride height
3) ride quality
4) wheel travel

In order to achieve each of these, proper spring rates are required and knowledge of static weight at wheel.

Clearance at ride height is the easiest to achieve and most threads on here are singularly focused on that. Simple solutions are centered around shock length increase (spacers) or spring preload adjustment (spring seat collars and adjustable spring seats). These are both viable solutions that can have different consequences. However neither solution adequately addresses the other objectives. If corner weights start to get big due to modifications proper spring rate is the only way to address all of the objectives.

most people aren’t thinking this way or tracking this. I myself have 6100 bills and use spring preload to dial in my ride height. Although I do know as I add weight I need to rethink things.
