Coil over question

Have any theories or arguments? I'd like to know your perspective.

 

I do agree with this.. Plus the alignment bolts on the lca to allow for the additional down swing of the lca. Unless there was a c-clip above the spring that could sit in a race allowing the shock body to rotate. But the forces would likely not make that easy and it would lose the adjustability of spring rate. But I know right where a crescent wrench could go for easy adjustability and the remote resi.

 

I was thinking something along these lines, excuse the poor edit



If stock height was the shock body threaded all the way down so the body bottomed out on the lower mount and you could still go up 3 inches before it hit a built in stopper to allow for enough threads to be in the lower mount for strength I think it would work good

 

The idea are sound, the downside is that you may not get maximum shock travel, which is something else to consider.

PK

 

I share that concern, as well as fair wear and tear over time. Our crappy winters and road salt tend to destroy anything that isn't simplified and robust, meaning that strut design would rot from the inside out as soon as some salty icy slush worked its way in there.

 

You know i could see that on a Xrunner but an off road truck that would limit so much travel it would be worthless.

 

Yes, but lifting the truck at all limits travel either (droop, or up travel) regardless of coilover correct? You can only change the travel by changing the control arm geometry, ie Long travel. Install any lift with stock arms and you are removing down travel for gained up travel?

Correct?

The best 80 hwy / 20 off with a lift would be to have a soft initial up travel as you have less down travel on bumps. Anyway, yes, having a lift will change the geo and the ride is stiffer. That is not necessarily a bad thing for a truck unless you want it to ride like a caddie...which the raptor does similarly on road. I tend to agree with OP that the shocks from the big 3 here etc could be better tuned in some aspects while allowing for ride height adjustability.

 

^x2 JLee it's just a fancier spacer lift. Cool idea, but wouldn't you rather have that many more coil wraps that provide you with useful travel taking up that space where the threaded body is?

I think this is the same reason you don't see your type of COs in trucks OP. We have a lot more room to play with than rally cars (which I know nothing about but I'm assuming they have a very small amount of travel with stiff as fuck springs) so the manufacturers use all that space with the coilover itself rather than messing with the adjustable shock body. They seem better applied to lowering applications (it's at stock height threaded all the way out and you crank it in to lower) rather than for lifting (it's at stock height all the way in and you thread out to lift). The more you crank that thing out the more shear you introduce to the shock body and the more likely it will break

 

You're somewhat correct when you say spring rate doesnt change, but what does change is the required force to compress the spring. If you have a 100lb spring with zero preload it will take 100 pounds of force to compress the spring. Take that same spring and put an inch of preload on it and it will now take 200lbs of force to move it an inch. That means the first inch of travel now takes twice the force. Thats what you feel, not the control arms being at different angles.

 

So other than keeping coilovers at stock ride height, there is no way to prevent a more harsh ride when upgrading? I would like 2.5-3" lift but all of the trucks I have heard about or ridden in are a bit stiff for the daily commute

 

If you would just forget about the adjustable part the OME 885s and nitrochargers will give you 2.5" of lift and handle like a dream on and off road. Install and forget. Bulletproof reliable technology. Doesn't get any easier.

 

My All Pro coilovers give a significant improvement over the stock ride, and I'm lifted over 3 inches on coil preload.

 

I am pretty sure allpro does not make coilovers

 

Very true.

It would be a catch all and worry over time.

Yes for legitimate mall crawlers..

This is my current setup. Except I have billies instead of the nitro chargers.

 

I am positive they do, since they are bolted to my truck.

 

I have heard of the walker evans, just didn't know they were made by allpro

 

Also, instead of preloading the coil springs couldn't I get a longer spring say by 2" and achieve the same lift as preloading without the harsh ride?

 

Exactly the idea I've been trying to sell you on.

Are the OME coils longer then? because I don't recall you saying that longer springs would be the solution I just remember you suggesting an OME setup, not a coilover with a longer than off the shelf spring.
