Are springs interchangable between a Disco and a 90?

[Datt]

Got talking to my neighbour about LRs today as he owns a late 80s 90 with a 2" spring lift. I have a set of standard height King springs on my Disco at the moment. The neighbour wants standard and I want 2" lift - so my question is are they interchangable so we can swap???

Thanks
Matt.

yes the springs are interchangable, the coil diameter is the same,

disco-deefer has slightly different spring rates and free heights so as to if what your proposing will work Id suggest swapping one rear spring on each and giving it a go over with the tape measure.

The 90's have the same spring diameter, but the 110/130 rears are a different diameter and wont change over with Disco/RRC.

The front sprngs from a Disco should give the 90 a similar lift, and the rears should provide about 1" extra lift.

Great, thanks guys. Now to sus out whether to swap dampeners, I'd rather keep my Bilsteins if I can.
