Here is LRA's spring rate/length/ride height chart.

Thanks Heaps Simon,
this looks like what I needed.

No probs at all. I've not had anything to do with LRA, but you may find that all of those springs are ground top and bottom, and that is fine for the D2 rear, but the front requires a cut and dog legged spring. I'm not sure if they will do that or if you'll need to run a D2 rear lower perch up at the front.

my D2 runs WHITE fronts,,
and I HAVE just installed a front bar(no winch)

so these should'nt sag overly Slunnie?

They're stiff for a front bar, but I doubt they will sag at all after the initial settle, even with a winch and duel batteries etc.

is WHITE usual on the front of a D2??

Many manufacturers are back at about 180-190lb/in for a Disco2 front and these in my opinion and from what I could research in the US and in Aus are fine for no bar, marginal with a steel bar and will return to standard ride height with a winch on the front.

There are a couple of manufacturers that have rates at about 220lb/in including Dobinsons I think and ARB have revised their 779 from a longer 180lb to a slightly shorter 220lb/in for their full load D2 front spring. I run a lovells 230lb/in and no problem there yet either.

270lb is pretty stiff, but I know of these being run in Defenders etc without problem, but not a Disco2 front. I'd say that they'd be a more typical rear spring.

I suppose the next question is why?
as in install these (I'm guessing from the factory-- ) on a D2?

The D2 has always been harsher at the front than BUB91,, (even with Nitrochargers )

maybe its just me comparing it to the luxo ride from the back half

Oh... Are these LRA (Rangie Spares) springs or factory springs? Factory whites according the above data are 110 military springs.

To get the luxo ride back you could look at softer rates with the appropriate length and/or shocks with softer bump valving.
