New Shape 2018 Fortuner - 2.4 GD-6 4x4 Auto - Suspension options?

Hi Everyone
So I invested in a 2018 Fortuner 2.4 GD-6 4x4 Auto as that is as far as my finances could reach. Children at university takes its toll! (yes, plural, 2 of them with a third on its way to varsity, so cash flow is limited).

Generally happy with the vehicle, but the suspension sucks!
When lightly loaded, it jumps over speedhumps, indicating that the suspension is too hard, with little give.
However, when I hook up a trailer, the tail sags and I find the suspension too soft.
In addition I find the car too low, did one 4x4 trail to test out all the settings and knobs etc, and came back with a scratched bumper (underneath) and I knocked the radius arm mounting bracket.

So in my opinion Toyota got it wrong on all counts!
I had a Hilux 3.0 D4D 4x4 DC that ran a medium duty OME setup in the front and a OME heavy duty setup in the rear, and that worked well for overlanding in Africa with a family consisting of 2 adults and 3 children plus an Imagine Trailvan.

Question is what do I fit on the new shape Fortuner? Any advice or experience would be most welcome!

Here are my requirements: I want a lift, I want a progressive suspension that will soak up the potholes and speed humps etc at slow speeds, yet firms up significantly when I hook up a 800kg trailer. I also do not want a soft suspension at speed, as I hate a wallowing ride.
From reading up on the topic, there are a couple of options and some warning tips.

Apparently lift is limited to about 25mm and even then you need to fit a drive shaft spacer (also known as a trim packer or tail shaft spacer) (ARB and OME have available) to prevent driveline vibrations.
Would like to hear from guys that have a higher lift kit - do you experience driveline vibrations?
There are a number of schools of thought on this topic:

Some advocate that you keep the standard coils and fit adjustable shocks. I like the ability to be able to adjust the shocks (Rancho and Tough Dog)
However keeping the standard coils will not give me any lift. So I will have to change the shocks, which I do not mind doing, and/or potentially fit a body lifting kit, which I am not keen on.
Some recommend keeping the fixed shocks in front and adding adjustable to the rear.
For heavy loading (overland travelling), it is recommended to add airbags to the rear suspension. (Gremeltech ...)

Then there are the various proponents of their favourite brand of suspension. I have driven previous generation Tuna's with EFS and Ironman suspensions, and found them too firm for my liking. Not sure of their new offerings.

I do not have experience with Tough Dog, Rancho, Amada, etc ... so if there are guys who fitted any of these, your feedback will be appreciated.


What do the Hilux guys fit on the front of their bakkies?

Thanks in advance, lets see whats out there!

Hi Herbie, wil ltry to give you some answers.... but please feel free to contact myself directly for more info,

We do on the Fortuner's 50mm Suspension without any side effects such as vibrations of any serious wear on any joints, the moment you go over the 50mm bracket then the suspension geometry start changing very quickly and the kit become much more expensive.

You mention you would like a progressive system, we did use progressive coils earlier but stopped manufacturing them, let me explain... the progressive coils sounds great... soft on the top and become progressively harder as you load your vehicle, ... the soft part is created by coiling the wire closer together as the moment you manufacture the coils closer the coil become softer the spring rate and if you increase the distance between the coils, the spring rate increase.
But the problem when loading, because the top part is softer... it will sag also quicker, thus when you load the vehicle it will sag very easily. I have found the linear coil springs to give better overall performance when it comes to daily use and load applications.

Remember shocks does not give any lift, unless you have a front shock with an adjustable spring seat, then only can get more height out of the shock with the standard coil spring. We offer 2x types of front shocks, std height spring seat and raised spring seat.... thus with the raised spring seat we can raise the front with the std coils or raise more with different coil springs.

I have airbags on both my vehicles, of one is the Fortuner... I love the air bags, gives perfect balance between comfort when the vehicle is not loaded and can be inflated to handle almost any load. There are 2 x types available for the Fortuner.... first the in-side coil type... not my first choice although its cheaper... rather go for the heavy duty unit which fits between the axle and chassis... these are unreal and go for the Firestone product, slightly more expensive but top quality
