Does anyone know a source of uprated rear springs for a Shadow1. Thanks Mark | ||

The heavy duty front and rear springs have been available here from Lovell's Springs for a considerable period of time however I am not aware if this is still the case: www.lovellsauto.com.au/ Closer to home, forum contributor Paul Yorke would probably be able to assist as well: http://www.everythingrollsroyce.com/index.html You could also contact forum contributor Richard Treacy who sources parts for Rolls-Royce and Bentley vehicles: http://www.spurparts.com.au/ Another probable Australian supplier of heavy duty [colonial] springs would be RA Chapman Automotive: http://www.chapmanauto.com.au/index.php/rolls-royce-bentley-specialist-spare-parts-repair/ . | ||

Hi Mark, I can supply Harvey Bailey ones. Are you after them to raise the rear height or are you towing with her? Cheers, Paul. | ||

Hi Mark I have fitted new rear springs on cars bought from the usual sources and wasn't that happy with the results so I had a couple of pairs made locally (Euro Springs Ltd Dungannon) and fitted one set to my Shadow one and the other to Barry Murphys shadow two Geoff Wooton also had rear springs made around the same time, all my measurements etc are in a thread about a couple of years ago. Richard. | ||

The levelling has been disconnected years ago on James Shadow project and everything appears to require rebuild to be polite! . We are thinking of heavier springs to overcome the rebuild of this in order to get the car useable for the next couple of years whilst we finish everything else . The rear springs need shimming or replacement as they have sagged . Mark | ||

Hi Mark I didn't answer your first query as I bought my rear springs in the US and figured the delivery costs would be too high to the UK. As a point of interest the company was Coil Spring Specialties in Kansas. I don't understand why you are thinking of fitting heavier springs - I accept I may be missing something here. My understanding is the standard springs are designed (with correct shims) to hold the car at the right ride height. The leveling is there to keep the car at this height as weight (passengers etc) is added. With the car unladen, the leveling system should be totally inactive, the ride height being solely determined by the springs. Here's a good thread which is worth a read: http://au.rrforums.net/forum/messages/17001/16457.html?1438295588 BTW - There was a short article in the Dec 17 edition of Practical Classics about an owner who was restoring a Silver Shadow. It was only a couple of pages and didn't give any technical information but it was interesting to hear the contrary view to "always buy the most expensive car possible". This owners view was an apparently pristine Silver Shadow can be hiding all sorts of horrors so it is better to buy one at low cost and restore it. The only proviso being that the work was carried out by the enthusiast to take out prohibitive labour costs. If you pm me your email address I will send you a copy. | ||

FYI, Shadows were fitted with either "standard" or "colonial" springs during assembly depending on their ultimate delivery destination. The main difference in the springs was the colonial springs were 'stiffer" as the diameter of the rod used to make the colonial spring was around 0.125in larger than the standard spring. When increasing numbers of second hand UK-delivered Shadows began to arrive in Australia, problems of rear end "droop" became commonplace which was quickly traced to the standard rear springs taking a permanent set. This did not occur with locally-delivered vehicles fitted at Crewe with the standard "colonial" springs. Local spring manufacturers quickly diagnosed and corrected the problem by making stiffer springs using larger diameter spring steel rod. Quite a few cars were fitted with these springs when the RROC[Australia] NSW and ACT branch Self-Help Groups were active. http://au.rrforums.net/forum/messages/17001/16457.html I have the actual spring dimensions somewhere in my archives and, if my memory is reliable, these may have also been published in "Tee One Topics".  . | ||

Hi Mark Have you tried Grayson Enginnering they dont do springs but do the rubbers that fit in between the coils, my Shadow 11 was sitting low on the rear and that was after having new springs and shock absorbers fitted after fitting these it now sits level and in my opinion has improved the ride, its taken out a lot of the wallowing but still gives a smooth ride.And from memory they where only about £35 pair ...I have no connection with this company just a satisfied user.....http://www.graystonengineering.com/coil%20spring%20page.htm Roger (Message approved by david_gore) | ||

I've recently fitted those rubber coil spring assisters and find that my Silver Shadow sits better at the rear with them installed. I don't notice any difference in the ride quality but I don't tend to drive too hard anyway. Getting them inserted wasn't impossible but took some effort, soaked them in hot soapy water to make them softer which helped. I jacked up the rear but didn't need to remove the trailing arm metal bands (or whatever they're called) and didn't need to detach the brake pipes. I had the use of a hoist which definitely made access a lot easier. So far so good. Some others haven't found them great but I'm happy enough for the moment as the saggy bum appearance is gone and I don't like saggy bums. I regard them as a cheap temporary fix and how long they will last I've no idea. | ||

Did this mod back in 2005 or before, still working well with the running extra weight of LPG. "Hi Bob only just seen your posting yes I agree with all the hydraulics in good working order. Fitted low down so on the compression loading the bump stop is still functional. A must with LPG and a full load, in my opinion. I know some fit heavy duty springs to get over some probs but the ride is not so good. Think I have heard about doing a mod on the fitment of antiroll bars. A job for the winter me thinks. Sorry to hear about the signs, I thought all of where you live had escaped that sort of thing. "  | ||

Patrick, Richard Treacy described the fitting of Turbo R anti-roll bars to Shadows and later derivatives on this forum some time ago: http://au.rrforums.net/forum/messages/17004/9918.html . | ||

Thanks David, I did not do the mod and as it now turns out my driving with age has now gone into the steady comfort mode. Something to do more with my wife me thinks. The car has just passed it's yearly test with no advisories however I notice the coil helpers have moved up the coil spring! Will look into the operation of the bump stop travel. |
