Hi Guys

I have lifted my ml in three steps:

1. I lifted the front 1" with the torsion bars. The right torsion bar then reached its limit with the left still far away from its limit.

2. I fitted bigger tyres: 265/70/17 (31.7") in stead of 255/60/17 (29.1").

I drove a lot in this configuration, but the bigger tyres were filling the wheel arches too much for my liking, and also with the sway bar disconnected during off road, I needed better clearance between the tyres and the body, so I proceeded with step 3.

3. Because the right front torsion bars were on its limit, I took it to someone that took them out, and moved them on 2 splines on the right side and one spline on the left side.
The rear shocks were also taken out and 20mm spacers were put on top.

Now my ground clearance in the front is 260mm and in the rear it is 300mm.:D

I can adjust the front more, but I leave a minimum of 60mm between the maximum droop and the current height.

Unfortunately not. It was made by a company who specialises in shocks. I could ask him what it looks like. I know he has also done 3 other ml's in South Africa, and that maximum spacer is 20mm. It gives a lift of 30-40mm. Spacers of more than 20mm will cause problems where part of the suspension will press against the coil spring when it is at maximum droop.

I remember the suspension/shock guy showing me how you could barely fit a piece of paper in between the suspension (upper arm) and the coil when the vehicle is lifted up and the suspension is at maximum droop. I am sure it is possible to fit the 30mm spacers but I will be surprised if it does not touch your coil at max droop. This guy do specialise in Billstein shocks and work everyday on suspensions. I know that it is not often that the wheels will be at maximum droop, but it does happen during off-road. I therefor does not want to have the upper arm link push against the coil spring during max droop.

As it is, the ground clearance on my ML is higher at the rear than the front. I lifted my front up to a point so that I have 60mm left before I have maximum droop (also as per advise from the suspension/shock guy). Otherwise there is not anough play for the shock in order to do its job properly during normal driving.

So in my case, the 20mm spacer at the rear gave me a little more lift than what I have hoped for. The front seems to me to be the limiting factor in how high the ml can be lifted and still function normal on and off road.

danie,
you're keeping good stuff to yourself?!

tell us about the skid plates you have on! i saw that!:)
any drawings left?

i plan on doing at least one for the trans oil pan.


hope i'm not off-topic, lifted ml is not complete without skid plates.
;)

The skid plate (bash plate as we call it) was made by a company that makes all sort of things for 4x4 vehicles, even front metal bumpers that can take winches and allow much better approach angles, as well as rear bumpers that can take one or two spare tyres. They made these for lots of different vehicles, including the Mercedes ML and GL. They even go colour coded on request.

I have actually removed my skid plate. It was running from under the radiator up to the second crossmember (covering the engine and gearbox).
I have removed it since I was replacing all diff oils and transfer case oil. I also replaced the eng oil level sensor as it was leaking oil.

I did not replace the skid plate for a couple of reasons. I feel the ML's engine and gearbox is well protected by design. As it is, you have to really bash your front bumper, radiator and the swaybar as well as front crossmember in order to hit your engine sump. The gearbox is also at a very good height and it's sump close anought to the front axle in order not to be affected by high crossover angles.

The vulnarable points on the ML the way I see it is the following:
1. Overall ground clearance. That could be rectified by lifting through bigger tyres and torsion bar setting as well as spacers at the rear.
2. The body parts on the side below the side doors. That is the part that will damage if you go over too sharp a ridge, since that part is lower than the metal chassis. To counter that problem I have fitted metal rocksliders that can take the weight of the vehcile and take the punches when I do slide over high ridges or rocks.
3. The fuel tank at the left rear is also exposed. If I can have a skid plate that can protect that I will put it in a higher priority than the engine/gearbox. A friend of mine had his tank damaged during off road.

When I do have time I will try and get a picture of my bashplate so that you could get an idea how they made it fit on the ML. :D

ground clearance: kind of fixed that - 265/70 17 cooper disco.st maxx.
didn't have time to take height measurements but will do that.
still wanting to fit spacers on the rear shocks...

rocksliders: i saw your posts and it's a very nice job.
i don't really need these, we don't have rocky trails/steeps over here.
i can see why you went for bfg mt's km2, they originate from rock crawler tire.

fuel tank is really an issue on rocky terrain.

protecting the transmission is still a priority for me.
it will be either a plate or a bar/s from side to side.

What is it thats stopping max droop on the front? Can that be modified?

I guess you'll be doing a body lift next.

No touching of my rear upper suspension arm on the coil, i swear. it is a very few milimetres close indeed.
i don't get why you where not able to lift the front enough to mach the rear, i did even if my car is probably more lifted in the rear than yours (bigger spacers & tires).
it runs great in this setup, i do some serious offroad and it's superb!

That is good then :)

It is not that I can't lift the front of my ML more. I don't want to lift it higher.

At shis stage the distance from the bottom of the mag (rim) to the bottom of the front fender is 740mm. Maximum droop measured at the smae place is just over 800mm. I want a minimum of 60mm left for the shock to work properly during normal driving and that is how I run the setup at the moment.

It is high anough as it is for all the off-road that I care to do, and it is also good anough for taking the family on holiday and also for going to work and back on the freeway :D

The one I had does protect the whole engine and transmission.

Unfortunately I don't have a better picture of it.:)

I have the template for the 20mm spacers (unfortunately sold out at the moment) that give about 40mm lift so if you want about 3/4 of an inch, I could make some like 10 or 8 mm. That should do it. Here is what the 20mm look like.

Thanks, they came out very nice. I never would have guessed Ii would have sold out inn my first 2 months. I've sold 30 sets already, all over the world. I am very excited about it.

Well done Bosch wish you all the luck in the world. One bit of advice though. Watch the bottom line, and make them better than they should ever need to be and not anymore. Just add 10% for luck.

that piece seems over engineered by about two orders of magnitude ;) ...i mean that is a solid piece of steel.
