Defender Coils

Thanks Kelvin, that's pretty close to what I got with the KRRS-04 springs, a bit too high for a Puma without a DC joint.. Looks like I will have to try the KRFR-03 standard duty ones, alternatively I'll contact Andrew at LR Automotive and see what they suggest.

I've had a look at my spring collection behind the shed (surprising how many different springs I've got :)) I have another set of Disco rears, with a Green/Brown stripe on them.

According to this chart, Spring Chart they are rated at 207lb/in with a 754lb rating with a 15.2in free length.

A Defender 110 with the two yellow stripes is supposedly has 154lb/in rate and 171lb rating ( probably a typo 711lb?) with a 14.5" free length.

So it looks like I might have another pair to try :) - getting quite good at this spring swap business.

I also have a set of rear springs with a Red/Green strip - 330lb/in and 643lb rating but I'm happy with the OEM ones with air bags at the moment.

I've had 130 front springs on my 2007 Puma for 230,000kms now. About 120mm to the bump stops. Original front prop shaft and unis, and it's been very good, so perhaps mine, being an early model has some different parts to the later ones??

I had the standard rear springs with Poly Airs, but eventually changed to Standard Kings (25% stronger than Std LR), with the Poly Airs. Seem fine, but maybe a little stiffer than I'd like when empty. I was tossing up whether to try HD LR rear springs. Does anybody have comment about the HD LR rears?

:eek:

I have a 130 and only 65mm between the BS's ?

Have the same springs as Jason and it still only had 120mm when new a long time ago (admittedly a Tdi, not a TDci)

Brid I'm toying with getting my inner helper spring re done. My rear coils are also Les Richmond, red green I think. They are his heaviest coil for a defender which is still the standard rate. I had a set wound to 17" which is about 1.5 longer than standard. This allows the car to sit at standard height full of crap.
Now the truck handles itself well with its expedition load, but because I'm lazy and occasionally drive a bit fast it ocassipnally bottoms . No bigy but have toyed with getting some new inner springs wound 1.5" longer to match the outers. And maybe set at 150 or 160 lb/inch instead of the standard 140 lb.
Bit of a science experiment I admit. I'm also toying with a whole heap of engineering I know little about.
So feedback welcome.

It seems most go for bags, which is my other option. Just the simplicity of empty coils appeals to me.

Looks like I've found the "Goldilocks" springs for my car. The Bump Stop measurement is now 90mm. I put in the 10mm thick Discovery rubber pad on top of the spring the came with them, I might take out but I'll wait to see if they drop first. The edge of plastic flare to wheel hub centre is 505mm. I think when I'm finished loading the car, it will drop another 10-15mm or so and maybe they will settle a bit as well.

I'm not 100% sure where I got them, think they may have come with a spare axle I bought from a Hong Kong V8 import, if so, the wreckers will be full of them.

I wondered if I made a mistake, so went out to check, as I was going from memory. That measurement would have been right, as I've put a winch on recently and it's 100mm now parked downhill, nose first.
