coil springs

Hi all just would like advise on the following. I run a 1984 110 and want to fit heavy duty springs to it, I don't want to lift it but just want it to stay firm at heavy loads, I am planning on overlanding and will be carrying a fair bit of weight, the only mods I have are a winch on the front and a spare wheel on the bonnet plus the rear mounted one, I may fit an auxiliary tank under the drivers seat, I would like specifically to know what make is reccomended and what poundage they should be, thanks, kirk

ive fitted a lot of britpart yellow h/d std height springs with their gas shockers for a local farmer whose fleet hauls a lot of weight about ,hes found them perfect ,you can also fit the helper springs that fit inside ,i could give you numbers of parts need to fit them

thanks for that, i was swaying towards the britpart ones, a lot seems to be down to peoples tastes and the price!!

is that it on the advise front, all you landy owners and no opinions whatsoever??!!
