I am about to upgrade my suspension on my 2003 GU. I wanted to lift the vehicle by 50mm and I will be carrying some heavy loads. I am finding that the standard suspension just doesn't 'cut the mustard'. I have done some research on a couple of products available, TJM's XGS and OME systems.

I wanted to know if anyone had any opinions on which product offered the best value for money, or if there are other suspension products that were better.

Deano,
My 2000 GU has Lovells springs, but is also pretty heavy, with Opp Lock dual rear wheel carrier, long range tank, steel bullbar, winch, steel roofrack, full recovery gear etc (3.28T before I load it up with gear). The Lovells are 4" front and 5" rear. The actual height increase (measured against a stocker) is 3" back and front. I have made no other changes at this stage and it seems to handle okay. IE: I have not changed the castor/camber angles or lengthened the the brake hoses. I was running without both sway bars for many months, but recently decided to re-fit them, adding Snake Racing quick disconnects on the front one.
I also have Polyairs in the rear springs just to be sure.
I can thoroughly recommend the Lovells. I also currently have Koni shocks which have been on it since almost new. At first, I had OME springs with the Konis which gave me a 2" lift, but as I kept adding more heavy stuff, those springs started to sag and I was back to the same height as a stocker......hence the need to add longer/heavier springs to take the weight. I've done over 117,000klm on those Konis now and will need to replace them in due course (after next trip to the Cape in September if they last that long).

Stick with any of the well-known brands and you should be okay; but be fair dinkum about how much stuff you will be carrying (maybe load it up like normal and put it over a weigh bridge). That way you'll be able to tell the supplier the right info for them to help you make a decision.
Cheers,

Roachie

Deano,
TJM and ARB both King Springs,
Lovelles Springs, all go stuff and a lot of them around.
The shocks are the real big decision. A lot of posts are out there and the finial choice is yours. The shocks on a coil sprung vehicle have to work very hard. My postion on shocks is Koni's.

Kings make both TJM and ARB OME springs but they are not the same, OME runs different spring rates and specifications. TJM are definately straight off the shelf King coils with a TJM part number. OME has a wider choice of coils to suit different application.
30mm lift, 50mm lift Medium Duty, Heavy Duty constant 200kg Wagon Coils. If thats not heavy enought go to the ute range which in a wagon are effectively constant load 400kg and constant 600kg.

Try Ride Pro.

IMHO they seem to be good shocks; fat buggers which should = lotsa oil & gas, which should, if they get the valving right = good performance. certainly they have improved my GU's handling.

All for a fair price, too, I thought

When I asked them about coils to replace existing ones, they were very interested in how/what/why I used the bus. From there they made suggestions, including recognising the need for camber adjustments

Deano, you may like to look up reinforcing the rear spring towers on the GU for heavy loads and shocks too. Have 12 mm plate over the top of mine side to side bolted into the towers using the provided bolt holes. Mind you mine is in a traytopper and I don't know how you do it in a wagon.

There has been some discussion on the www.outerlimits4x4.com site and I have pictures there too. It is best to put in the extra when you have it all bared.
Cheers,
Who?

John,

cheers for the reply. I don't think I will end up carrying so much that I will require the towers to be re-inforced. But its worth a thought.

Cheers

I bought my '02 GU s/hand with the TJM 50mm lift & XGS already fitted. It's was soft in the rear & sagged badly when loaded. I have fitted the polyairs and upgraded the shocks with adjustable foam cell Tough Dogs. This way I can maintain the softer domestic ride, screw them up for the heavy stuff and the poly bags add support especially when I've got the 2tn boat behind.
Check at Opposite Lock & this site

has some good info about suspensions, phone Kirk.

Thanks for the tips. I am interested in those Tough Dos and will start doing some research into those.
I was a little disappointed to listen to the ARB people bag out other brands at the recent 4WD show here in Syd. Turns out the srings come out of the same factory !

Thanks for the reply.

Cokca,

yep in Sydney, down at Cronulla. You ?

How do the foam cells compare to oil or gas shockers.
I checked out that site, looks interested. I bet the 9000X series that are adjustable are expensive hey ?

Whick Opp Lock store did you get the tough dogs ?

Deano I'm up the nthn beaches & dealt with the Brookvale store. I visited a couple of the local suspension specialists but after a while you get info overload. I was looking at Koni because of the feedback from the forum & I got a recommendation for the TDogs from three outlets. The Koni were going to cost me $1400. (first quote)

I got the 45mm (bore) adjustable foam cells
AutoAlliance (Kirk) quoted $1040 and OpLok quoted me 5% less - saved 52 bucks.

Here's a couple of sites that will give you some info. I think you'll find the gas shocks are not the best for 4wd applications.

Bob,
Which Tough Dog units did you choose?
The massive 53mm bore Ralphs?
The new Heavy Duty 45mm bore adjustables?
The smaller 35mm adjustables?
or The foam cell 35mm jobbies?
I'd love to get the Ralphs but at $260- each, I could get a set of TJM XGSs and then send my Konis away to be tweaked up ready for next time.
Cheers,
Roachie

Bob,

Further to shocks, what spring option did you choose? Interested to know feedback on the comfort lift springs vs next stiffer, I think heavy lift.

Roachie, mine are the standard 35mm foam cell & I have had no trouble so far but if they die I would like the 45mm adjustable.

Hugh, I put heavy on the front as I have a winch & extra heavy on the back as I have draws & tow the camper. I find the ride better than standard set up.
