My experience / tips replacing coilovers - BOTH WAYS (LCA vs. Knuckle method)

[PWillette]

Yes more brake dive than the 2.0 bilsteins with the winch and bumper. @87-Z28 springs are key no doubt. One would assume the HD springs from eibach were best for the weight I have on there (not forgetting all the 3/16" skids). Brake dive was more but was still very controllable in a hard brake.

I'll be on the trails weekend after this. I look forward to seeing the difference all say is great. Wheeling around here is slow and all the reviews said the eibachs were not good at fast, and great at slow, so I'll report back. I plan to do the same trail I did a week ago on the sasq bilsteins so I Can provide a good comparison.

Was going to ask if you went w/ the HD springs, will be interested in your comparison. When Eibach originally released the 2.0s for the 6G there was no HD option so I'm on the standard springs w/ #160lbs of bumper and winch. I was only able to get 2.25" of lift up front on the standard springs.

I reached out to Eibach because I was in a similar situation, didn't have the HD springs at time of purchase. They sent me a HD front spring free of charge, "warranty." Made a huge improvement, I thought over the Billsteins, but I am in MI and there is a lot of slow wheeling.

Can I borrow that?

She’s more than happy to help anyone out. Just brace yourself for what some might consider an excessive use of the C word if there’s something fighting her

Seems she went with the “remove UCA and entire knuckle option.”

(Yes, she’s putting the original yellow Blowsteins back in. Or…bilservoirs…? Anyway-Benjamin button de-build is ongoing)

That's great, but.................................can she cook?

Some guys are just lucky I guess. I won't ask any other questions, I promise.

You’re gonna love them on slow trails.

@SierraBronco she's such a cutie and who cares if she can cook as long as she can change the suspension. I'll make the bacon and eggs in that case!

Ever heard of "euphemism"?

@NC_Oak Nice write up.


Gonna annoy some people with this one, but what good is B6G if you can’t throw stuff out there.

Spring rate is KING, the damper merely dances to the king’s tune. And that tune can change a crap ton whether slow rock crawling or high speed handling. Way too easy for people to blame the damper and look for holistic solutions from the damper. This thought pattern misses the mark a bit.

Spring rate gives you real power to affect handling and shock travel. Damping rates only provide perceived power and let you fine tune the strut response. Relying on damping to control suspension response relieves symptoms instead of curing the disease.

This is a good point, it may be that with a stiffer spring the Eibach's may perform better than they currently do. Unfortunately, there's not a lot of published spring rate info on the Bronco, so I honestly wouldn't even know where to start.

Also randomly changing springs is a major pain in the ass. I would want to have some idea of what my results would be like.

absolutely. My comment is just for awareness. It is not on the consumer to design their own spring rates or swap in a bunch using trial and error until they have something the like. But they should perhaps understand the critical design parameters.

many of the B6G coilover manufacturers started with a one size fits all approach. And some of these cost a few grand. Wtf. At a minimum there should be 2-3 different spring rate options. People are running many different weights with their builds. And using their broncos differently, slow crawling, fast desert running, or daily driving. There are many different sway bar options, different diameter bars, damper links, full disconnects. BUT ONE SINGLE SPRING RATE IS FINE FOR MOST BECAUSE THE DAMPING WILL TAKE CARE OF IT.

The manufacturers market the fancy damper properties and down play spring rates. Don’t get me wrong , the adjustable low and high damper settings are great but not the be all end all.

Well, Ford has a ton of different spring options for the Bronco straight from the factory, all selected by computer to the specific Bronco. So it would make sense that if the sping rate is king, then this is a necessity to getting the best ride quality. There are fewer shock options than spring options for the Bronco.

I appreciate your deep dive in the suspension thread, I don't understand it fully yet, but that happens when you let a psychologist loose on engineering matters. I can tell you how it makes me feel though... LOL.

Hit a trail up saturday, same one I did last before I swapped the coilovers, wanted to make the best comparison. I do like the eibachs a lot. the soft valving works nicely in 4-lo, crawling. I wouldnt say there is a huge difference from the sasq bilsteins, but certainly softer which was nice will transitioning from rock to the next, or obstacle to obstacle.

A couple off camber dips sending my rear in the air, the front coilovers compressed nicely with a soft rebound.

The handle speed humps in parking lots very nicely. The bilsteins were more stiff and sent the impact into the truck. The eibachs soak em up.
