Quick Spring Question

Hello, getting new suspension today, Terrafirma standard height shocks and standard springs. Though I can't seem to find any rear springs for a 90 that arent heavy duty. Are all the rear springs on a 90 heavy duty? And yes I am looking at normal springs and not sh*tpart yellow heavy duty or whatever. Thanks - would get lift - really want to - but can't be fooked for castor correction and so on.

google nrc9448 and nrc9449

Cheers for that

2" lift is fine without correction arms...
