Re: T30 Suspension Lift
Hi Everyone,
So i have a suspension issue. I have the King Spring (30mm) lifeted coils. The KDRR47's. With my standard struts. I have never had any issues and I previously only carried the roof top tent (50kg), 105ah thumper (40kg ish) 60L fridge (35kg ish) plus some camp gear, clothes etc when fully loaded. I have now added my tyre trek rear wheel carrier with dual jerry can mounts which weighs 115kg fully loaded and I always empty the jerry cans as soon as they can fit in my tank so that I don't have excess rear weight. I have done 6000km since installing the rear bar (I don't always carry jerry cans so the usual weight is only 75kg ish. There is a visible sag in the rear of the car compared to the front (I have lost height due to weight). I have noticed excessive wear on the rear drivers tyre (inside of the tyre). I had my tyre replace and booked it in at at a wheel allignment and suspension place. They checked the alignment off the ground and it was normal but under load it is 2 degrees out on the right and 1.5 degrees out on the left. They have told me I need more height in the rear to compensate for the extra load. The front can stay the same as that is perfect.
My question to the xtrail community is do you know of any brand that makes a heavier duty spring than the king spring KDRR47. I will need a higher than 30mm spring lets say 50-60mm raise so that with my weight it sags to 30mm lift from standard. Other question is would a strut spacer in the rear only fix my issue as the suspension guy said my height is the issue and they want to lift with a heavier spring. I'm thinking a heavier spring and new strut in the rear to compensate for my weight. leave the front as is.
The suspension guy is doubtful that there is an off the shelf spring that I can buy to solve my issue. I do have the option of getting the car weighed and getting a custom spring made for around $350 per pair (ball park figure from where I got my original king springs) that will do what I want it to do (plus struts and fitting).
Thanks in advance for the advice. I'm really getting to the limit of my xtrail but dont have the permission yet (from the boss) to buy a new 4wd. Maybe this will push her over the edge and my T30 may go up for sale

Re: T30 Suspension Lift
Hi Max,
The strut spacers will raise the suspension the fixed 50mm but should not be used with raised springs so that problems with excessive CV joint angles and stretched ABS sensor cables do not occur.
Did you get a measurement of the new settled height of your sagged raised springs ?
If more than zero above normal height then this could be a concern.
The spacers cost $200/pair (when I got them many years ago) so if the suspension place guarantee the custom springs for $350 will last then I would say these could be your best option.
The only concern will be the stiffer ride in the rear causing loss of traction around bumpy corners from the harder rebound of the springs when unloaded.

Re: T30 Suspension Lift
Hi Kev,
I didn't know there were CV joints in the rear. I' waiting to hear back from the suspension place to see what they come back with. Haven't taken any measurements as of yet.
What if I put a 50mm spacer in with a firm king spring which is a standard height? I would only be getting the lift from the spacer then as the spring was a standard height. I like the stiffer springs is all.

Re: T30 Suspension Lift
No problems with any type of standard height stiffer springs regarding your CV joints Max.
You'll just notice a harsher ride when unloaded, similar to what you get in a ute.

Re: T30 Suspension Lift
Hi guys,
Coming from Vitaras to XTrails, I have a question surrounding a solution that the Vitara guys have well sorted out.
Has anyone tried a budget lift using springs out of other cars?
The Vitara guys use springs out of particular Commondoors, and that gives them 3in lift, whilst not jeopardising ride quality (like we experience with King Springs, which, in my opinion, tend to be way too hard).
I had 3in springs made up before, only increasing coil diameter by 1mm to accomodate the extra length whilst not making the ride harsh, but I do like to experiment and do all my own work anyway, so I don't have to pay for labour.
I look forward to your reply.

Re: T30 Suspension Lift
I don't know about the Vitaras Syd, but with the Xtrails there are 2 things which will limit your lift to 2" and they are the strut and the CV joints.
The longer the spring there will be less downward travel you will have before the strut bottoms out and chances are the higher number of coils will also lessen the amount of compression the strut can do so your upward travel will also be less.
Atleast with the spring lift you won't have CV joint problems because they can only flex as much as the strut lets them which will be no different with the standard struts. I don't know if anyone makes longer struts for the Xtrail but that could dangerously increase the CV joint angle and cause faster wear or failure.
