Loss of articulation

[M.Allison]

Hey guys,

I took my rangie out 4wding today and i noticed im not getting near as much articulation as i did when i had my air bags in....scratch that im not getting any at all :eek:?

what are the possible reasons for this?

(for anyone that doesnt know i have a spring conversion with a 2" lift)

p.s i havnt changed my shocks from standard could this be contributing to this??

thanks guys

If you're running the same dampers (shock absorbers), then you must have very high rate springs fitted (as in heavy duty).

I suspect that you have answered your own Q :p

"im not getting near as much articulation as i did when i had my air bags in"

You've hit the nail right on the head there.

[M.Allison]

so im confused is it because the springs are preventing my articulation?

could someone please explain how it all works.....because im confused lol

Thanks Mike

If you had good articulation with the airbags and now you have poor articulation with coil springs and all that has been changed is the springs then....



clearly your coil springs are limiting the articulation.

What is to explain?

So ... Tell us the model numbers on the coils // and the shocks

ok that is probably my fault for the way i worded it. I know it is my coil springs to blame but i want to know "why" i have lost articulation, or maybe i have gotten articulation mixed up with something else.

this is the best way i can explain it.

when i park on a hill and the car is on an angle normally the the wheels on the slant will level out. Now when i park on the same hill the wheels stay on an angle giving me less tire on the hill.

is that articulation?

thanks

they are Arnott's spring conversion and shocks are the stock ones that came with the car. I have 2" spacers also from Arnott's

Thanks

When you park on a lump ... Does it do this??

WTF :confused:

Articulation is the flex available from both front and rear differential. Measured with one wheel compressed and the other extended (droop).

In the photo of the yellow beast above the front drivers side wheel is compressed as opposed to the front passenger side wheel which is extended, this is called flex.
The rear differential is also flexing, oposing the front differential. What you see there is flex/articulation.

If you are talking about the ability to self level the suspension at rest like when you had airbags fitted then I am sorry to tell you this, but there is no way to change the ride height of the springs to compensate for angles in the terrain.

Hey,

Thanks guys for all your help now i realise that i was wrong :( lol but the main thing is that i have learnt something.

on another note what do i do if ive lifted it two inches and in reality its more like 2 1/4 inches what shocks do i put in because ive noticed the shocks "bottoming" out when i go over bumps and that (they are still standard).

Thanks guys

Personally, when I change any springs for one of different height, be it taller or shorter (as I did on my Falcon) I always look at the travel of the shock compared to the spring.

Springs and shocks will provide the travel but the bump stops should be the items that dictate "stop" of the travel. If the shock is topping or bottoming out before the bump stop comes into play then you would have to be causing damage to the shock.

We have a 3 inch suspension lift in our RRC and are using suitable height PRO-COMP shocks.

Maybe someone here will be able to point you in the right direction for a shock to use or to a company that can recommend and if needed fit the right ones for you.

you can move the front shocks to the rear and get modified LandCruiser shocks for the front. Think I mentioned the model numbers (Bilsteins) in another post. Works on my 2" lift, but I have Arnott Gen III's that give more travel/flex anyway. You might get away with just another set of fronts for the rear... and longer bump stops from HRA.
cheers, Paul.
