Just got my 2013 DMax back from OL after the suspension upgrade, I was a little nervous after reading some negative comments on the forums but I figure the only way to find out was bite the bullet and get it done.
OL and Tough Dog people assured me that the lift provided (40mm) was within the safe range for the CV's and stated that they have installed many kits like mine with no issues.
I went for the 0-300kg rear leaves, 9 stage adjustable shocks, front strut assembly to suit bar and winch extra weight, urethane bushes, and greasable shackles.
After measuring I found this:
The back went up slightly less than the front approximately 35mm and the front up 45mm, this brought the car closer to level than it was previously, there is still a little rake with the back being 10-15 mm higher than the front.
With the shock adjustment set to mid way, the very scientific bounce test on each corner of the car showed a definite improvement with the car settling after just one bounce ( previously 2-3).
The ride on the roads around home which are tar but pretty rough in spots was great, less body roll around corners, almost no nose dive on breaking, and smooth.
Haven't tried it on the dirt yet so cant comment on that, we will try to test it out prior to our trip to Cape York in June.
There was no vibration or shudder that I could notice.
On inspection of the CV's they are clearly at a steeper angle but don't look too bad, I took some photos prior to the new suspension going in so I will compare after I take some new photos.
Next step is to load the car up with all our gear,hook up the camper and see how it sits and drives, Previously the rear sagged approximately 20mm when we did this but because the rear of the car sat higher than it does now it sat pretty flat, I'm a little worried that the car will now sit low in the back when loaded up, and with the camper on.
All in all pretty happy so far.
Cheers
Dave

Does the vehicle have active or electronic stability control?

Then you 'may' be illegal.
I was under the impression any vehicle with ASC or ESC was not allowed to have any mods on suspension or steering components.

Does your install comes with engineering certification/compliance?

Apparently there have been a fair few Late model DMax's done, probably other makes too with esc, no mention of it by Ol or Toughdog suspension.
I'l have to make some enquiries.
If what your saying is correct its going to make it tough for people buying new 4x4 vehicles as Esc and traction control are pretty common on modern cars.

From what I have read, there is ESC (Electroninc Stability Control), common in modern cars, and ESC (Electronic SUPENSION Control), not so common, the later being the one thats an issue I believe.

This was addressed about 4 years ago by the major suspension manufactures when there was concerns raised, proved to have no impact of stability control.

There are thousands of vehicles with raised suspension and stability control.

Did they realign the front end for you?
After the front coils settle it may have to be done again and the rear end won't be so much of an issue.

Because it is a new vehicle the 2 to three on the bounce test should not be there, 1 to 1/12 is normal.
You are lucky you have the new model Dmax as the previous model suspension allowed the wheel to rebound 4 to 7 times shortly after new. Those shocks renamed to shockING.

With a constant load in the tub and a camper on the towball you may end up requiring an additional leaf in the rear so the suspension travel retains some upward ability to cater for conditions.

Worst situation is going at the bottom of a dip when the camper mass ie, increased down force on tow ball, makes sure the normal clearance is almost nil and then you hit a bump.

Be more careful in that situation.

Yes they did an alignment, in June we are heading to the Cape, I'l get it checked before we go.
The bump stop clearance was only about 50mm prior to the suspension upgrade, I havnt measured it again, but at a glance it looks close to double that now. I will measure it unladen and also fully loaded and camper hitched up.

Very interested in this as I'm looking at options for my BT50 dual cab. What is the ball weight of your camper please?
Cheers

have had mine lifted for nearly 12mths (different mob) and it is still doing well after 25K Kms. Don't have a camper to tow but my rear went up 75mm and the front 35mm so it kept (increased) its rake. Still not a bad 4wd that does what it's supposed to do. Enjoy your trip - I'm back into the deserts for a few months in a couple of weeks.

I;m another who has done the upgrade, I also have the 300 constant. Been nearly a year now and very happy with it. Towing our camper over corrugated roads, even the wife commented on how nice the ride was.

Enjoy your ride, the Dmax is a very good 4x4 :)

I tossed up the idea of the 300 constant rather than the 0-300, but was talked into the 0-300 by OL, not sure if it was the right choice yet as I hoped to retain a bit more rake to compensate for the drop with the trailer on. I have been advised that fully loaded and the trailer hooked on it will still retain some rake, I will find out soon enough.
I guess I could have an extra leaf spring fitted if required.
Cheers

hi , had the suspension upgrade in may 2011 when max was just 3 months old also had it lifted 40mm. definately picked the wrong crowd to install it but that said the suspension has done the job asked of it ( our van has a tow ball weight of 250kg ) and has followed max up dry river beds and some not so dry. strez, odnadat, warri gate, etc even with all the extras I found that I have to run the tyres at D-max specs . I dropped down from a very tricked up landcruiser ( long story ) and max is 4wd number 14 for me and it continues to impress. just finished making drawer system and last on the list is limited slip in the front.
Cheers warren
