My 98 300TDi Disco has a +2" lift using Old Man Emu dampers with HD springs. I'm thinking of fitting trailing arms, radius arms and eventually a cardon jointed prop.
There seem to be a number of options when it comes to trailing arms.
Cranked Trailing Arms -

Just fit a pair of cranked trailing arms and some good tyres.

to be honest i wouldnt bother with the rose joint type as if you get crap in there its another part to be binned , just look what sand and grit do to bearings and breaks . i would just go for cranked arms then its only a quik bush change if it all goes wrong .

Thanks Guys.
235/70/16 BF Goodrich A/T's are fitted at the moment, although they have about a year left on them. Money permitting I'd love to fit some Mach 5's with the same tyres on, but slightly bigger. The 235/70's (stock size) look a bit like roller skate wheels with the lift! :grin:
Now what's the difference between "cranked" and "double cranked" trailing arms ? I can see visually that there is an extra curve in there, but what advantage/disadvantage does that give?

you dont need new front arms on a 2" lift, if you fit those the prop will probibly bind due to the new pinion angle.everey thing moves together with the origional parts. and i wouldnt use qt arms if i were you, they break!

I fitted 3 degree correction arms and double cranked trailing arms from qt -

I've got the gwennn Lewis rear trailing links, they are bullet proof if a little heavy, basically they are twin tubed arms and will stand up to you dropping the car on them, others don't.
On the front I have QT 3 degree arms, I've heard all the arguaments but for the use you are going to put it to you won't be breaking them, they are pretty damn tough things.
By castor correcting you will quickly need a TD5 front prop (cardan jointed at the gearbox end) but the steering will be much better and the spring/shock seats will not be bound up.
Other than springs and long shocks that should more or less be it. I had to space both my anti roll bars and fit longer brake lines but i can't thinbk of anything else.

I'm using the adrenaline double cranked trailing arms on my RRC. I think they are great, very solid. They move the axle back a bit so it's in it's original position and the double crank (bends) allow the axle to stand upright in it's correct position. I've got some QT castor corrected radius arms but haven't fitted them yet. Found out correct castor is essential the other day - While being towed the steering wanted to go to full lock. I had to hold the steering wheel quite tightly to keep it central. Never had this problem with standard setups.
The adrenaline radius arms look good in fact all the kit they supply would be fitted to the RRC if i had the money!
You may also want to consider an adustable panhard rod to keep the axles in line.
