Sheffield Posted September 20, 2015 Share Posted September 20, 2015 At present I am engaged in the entertaining task of replacing the shock absorbers on my 1996 300TDI, using Procomp ES9000s. However I have found the passenger side front spring is broken at the bottom seat. While it still supports the weight I obviously do not want to put it back on. Nor do I want to wait while the near useless French parcel carriers bring me some new springs. I do have amongst my treasures a set of four coil springs from a RRC V8. These were originally supplied by Famous Four of Louth, and are I believe their own spec. I am wondering if I can use them on the Discovery. FF do not say what spring rate their springs are. so I can not make a comparison. The original unbroken spring is 405, while the RRC springs are 380 free unloaded length. I have a set of spring isolators which brings the unloaded length to 385. The vehicle is an ex Police Discovery, RHD, so I assume the original springs may be Police spec. The vehicle is not used off road, and most of the time carries only me. It does not carry an excess weight. Does any one have any adfvice, please, as to whether I can use these springs, or will they be too soft, especially with the relatively soft Procomp shocks? I am concerned it may wallow too much. Thanks. Quote Link to comment Share on other sites More sharing options...
Nigelw Posted September 20, 2015 Share Posted September 20, 2015 If you have ARBs as I suspect you might, then nothing to worry about. spring rates vary as do uncompressed spring heights, I had some genuine springs for an old RRC and a set of HD std height springs, the HD springs seemed shorter but had a much higher spring rating, the genuine springs seemed to compress to a similar height when under the vehicle. Probably not much help but I would fit them and plod on Quote Link to comment Share on other sites More sharing options...
qwakers Posted September 20, 2015 Share Posted September 20, 2015 +1 and if you dont like it you can always replace them. rear springs are easy to change. remove bump stop, use scissor jack to jack between chassis and axle wait for spring to fall out, replace spring, lower jack.

Sheffield Posted September 26, 2015 Author Share Posted September 26, 2015 For some reason this seems to have been reported. Sorrry. Quote Link to comment Share on other sites More sharing options...
Sheffield Posted September 26, 2015 Author Share Posted September 26, 2015 Well, many thanks for your advice. I have fitted the springs and dampers, and they are indeed fine. The ride is smoother, without the hardness it had before. I suspect it would be too soft for a heavily loaded vehicle, or one hard driven, but for me with road use only it is fine.
