Oh crap

I recently fitted some Koni shocks for my 80 series suited for a 2" lift. In Brissy the other day I stopped in to dobinsons to measure the wire thickness of the springs to find out what they are rated at, and turns out the springs are 3" heavy duty. I had thought they were a 2" spring.

The question is: will shocks only made for a 2" lift be OK with my 3" heavy duty springs? I am leaving for a double crossing of the Simpson desert in a few weeks.

Now I know I have a 3" lift I don't want to go any lower! But would 3" normal duty springs be ok? I plan to fit airbags in the back. The old girl is just too rigid.

You will eventually 'top out' the shock, did you ask Dobinsons? I would ask Koni (the place you brought them) what the max extention lenght is for the shocks.

A 3" lift is still a 3" lift even if the coils are softer - a 2" shock remains a 2" shock no matter what coil you put in.

as said you will top them out. If its too rigid now, why would you fit airbags?

Of course the shocks top out..even the Toyota ones do, thats what keeps compression on and holds the coil spring in.

A 2" or 3" spring doesn't aways equate to a 2" or 3" lift. It depends on the mass of the vehicle, whats extra mass you have screwed/fitted to the vehicle as well.

Are the Koni's the 8 or 9 series. Mostly available are the 8 series, and you will find the 2" lift (if we use such a term) ones are pretty much standard length of the standard Toyota shock.

The wire thickness is often a guide to the load carrying capacity of the spring..the lift height relates to a standard mass vehicle.

I run the king springs 600kg ones on the rear of my Cruiser..on a standard mass Cruiser, that would probably give a good 3" lift..but on mine with the fitted gear..barely 2".

What was the point of fitting air bags again..?...

I think he meant a softer 3" lift with air bags to help.

here is an important thing to consider.

In your suspension what limits the upper suspension travel.

If it is the shockabsorber...and you have 2 inch lifted shocks and 3 inch lifted springs...um...you have a problem.

if it is some other mechanical contrivance..it should make no difference.

BTW.....under current regs....a 3 inch suspension lift without engineering is illegal.

cheers
