Bilstein 5100 + eibach coils maxed out

sort of. a Stiffer coil (increased spring rate) will elicit the appearance of more "lift" because the spring is simply sagging less. if the valving of the shock was not made for that rate, the shock will perform worse.

however, if you had a 14" spring at the SAME RATE ft.lbs as the 13" spring, you could then have less displayed pre-load on the clips, because the longer spring would occupy the perch the same way as a pre-loaded 13" spring ran up the clips.

13" 600lb spring ran up x clips = 14" 600lb spring with no clips moved.
try to picture your shock shaft becoming more or less exposed from the body by pre-load.

changing the spring rate (the ft.lbs) should only be used in cases of more weight over the shock, and should ideally match the valving.

 

I think 3” on a 3rd gen is a VERY bad idea. There is literally not one good thing that can come from that. 1.5-2” is the sweet spot.

 

Yes I agree a longer coil would be ideal and possibly the route I will be going

 

Why?

 

Only if not adding supporting mods. Uca's, ecg, etc

 

I am still confused how a stiffer coil with the top notch set is only yielding about 3.25 of lift..... feels like it should be closer to 5 inches.... :/

 

define no issue, because running them the way the manufacturer intended and the way they are sold are two completely different things.

there is an 85 page thread filled with problems.
https://www.tacomaworld.com/threads/eibach-pro-lift-kit.545060/

but the longer coil is only applicable if you are going to NOT run the spring up the clips, because the extra INCH is functionally pre-loading the suspension already.

 

Yeah I meant for the fox coilovers I looking at lol

 

see this where were back to square one , and exactly what the "cruxx" character just couldnt wrap his head around. The stiffer coil is merely 'holding' the weight static, rather than 'suspending' the weight like a hammock. It just 'looks" taller.

you have to remember there is only a FINITE amount of shock shaft from eyelet to eyelet. You eat or consume the remaining shaft/travel by either
-preload (via clip settings)
-a longer coil (pre-load ish)
-spacers (bye bye correct down travel)
the "lift" is an illusion produced by consumption of the available travel.

thus to properly SUSPEND a truck at a new height and maintain ideal up&down travel, you would need a whole coilover assembly that had the appropriate shock shaft lenght, body length and perch settings to keep everything in that range.

LOL just wait untill we get into the effects of "progressive (trd-pros) and Digressive (bilsteins etc.) and what happens when you fuck with those.

if springs provided "lift" you would see 10million people making 16" springs and it would be case closed. The tacoma was configured off of a 13" factory spring at a (disputed 650lb-700lb) rate. Off-road marketers have utterly ruined the meaning of "lift" and "ride-height" to the point its semantical nightmare

 

What is he spring rate of the coil you have on there now?

 

I think I get what you're saying. It kinda sounds like you still think I'm using a spacer lift which I am not. I would have assumed the 5100s were longer shocks to account for the 2 inch lift????

 

I dont know it all came as a kit via the link.

 

Take this guy for example:
Eibach pro lift kit

he needs to increase spring RATE (+ft.lbs) in order to offset his increased static-weight to maintain ride-height at current spec.
-poster states he lost 3/8 after adding 115lbs
-the spring is now being loaded even further.
-raising it a clip wont help anything, its only adding pre-load further.

Increasing spring RATE is how you offset static-weight gains in the truck, to maintain a specified ride height.

 

You ARE increasing spring rate by increasing preload though, I'm pretty positive

 

Did u get 600# springs?

 

Spring stiffness stays the same.... but the more compressed a spring is the more load it takes to compress it further.

 

I dont know. I'm going to email bilsteinlifts.com and see if I can get all the specs. I'm pretty sure the installer threw Way all my packaging

 

lol I know what your using and I am trying to explain to you here. this is what I mean by fraudulent marketers exploiting customers.

The shock itself was never "longer" in a technical sense. IT was merely using an over-spec size spring to eat up pre-load and an over rated spring rate to give the false appearance of lift @ a given ride-height.

its literally all smoke and mirrors, coming at the expense of your ball-joints, alignment cams, CV's, drive-line and god knows what else.

 

You just contradicted yourself.
