Land Rover Springs-Range Rover
My '92 needed new springs. I wanted some lift, without going wacko on ride quality. After too much web surfing and listserv notes... I decided on trying the LR HD springs. Then, after more web surfing and emailing, I discovered that the front set of the factory HD spring set appears to be simply D90 rear springs. Robert Cork told me he saw a pallet load of these at RoversDownSouth, and sure enough, I bought the 2 front springs for 22.50 each. These springs are NEW TAKE-OFFS, probably on a vehicle for a few miles.
Hunting down the rears was harder. From other owners of these springs, the rear set are Pink/Red/Yellow, but I couldn't find this color coding on the spring info web pages. We agreed that they are progressive rate springs, but that was as far as I could go.
I spoke with RN, and they said that the rear of that set was a NTC8572. I could order these springs, but I couldn't find any info on them on the internet sites, either. Mansfield sold me a set of the springs, which their site claimed them to be for a Discovery DSL.
I ordered these springs on a gamble that the fronts and rears would match up and replicate the Land Rover Heavy Duty spring set for much less money than simply buying the set brand new.
I did all this, and installed them, all pictures are linked below, and so far I'm happy with ride quality.
Here are three vehicles with what I believe to be Genuine LR HD Springs:
Well, I've been riding these springs on midwestern roads for a bunch of months now... and guess what... they're too stiff. Yup, too much jarring around, hard "blams" over railroad tracks, and too much jousting with small road undulations.
I'm removing these springs and will buy a set of brand new OEM springs and run them, and see how I like them in my environment. I'm sure that the HD springs would be fine in a no-snow environment where the roads to and from work and grocery are much better than here. The truck really does handle better with the HD springs, much less body roll, but the ride quality loss is not acceptable trade at this point. I will post the results of new OEM spring installation here.
My 92 had these springs installed, I assume they are original to the truck except for the right rear, as it appeared this spring had been replaced at some point :

Rovers North indicated that the rear springs in the LR HD set is a NTC8572.
Of course, I can't yet find that part number on the internet sights for Rover spring ratings.
Rovers Down South Web Site has D90 REAR springs for 22.50 each:
The LR HD for RR Front appear to be D90 Rears
