120 Rear Springs

120 Rear Springs

I've got a 1954 120 OTS that sags considerably in the rear end - maybe 2 inches - because of spring fatigue. I've been told that the springs can be re-bent, but it may not last - that they may sag again shortly. I'd like to use the original springs rather than replace them, if it's wise. Does anyone have experience or suggestions? - Scott Allard

British Auto has replacements listed for the 120 in their catalogue. I had the same problem with my 150 and replacing the springs made a tremendous difference. - Ron, 150 dhc

You can have additional leaves made and/or added to youir original springs, which could help raise the rear end. Also, 'helper' springs could be added betwen the axle and the front spring shackle. If your springs are still wrapped in leather gaiters, or if you desire to add 'parcelling' (spring wrapping in a tar-impregnated cloth bandage), then it's possible that these extra leaves won't show. The original spring leaves can be reformed (bent) and then re-tempered; this could give you the original ride height with the original leaves. As they originally deformed with age and presure, they'll doubtlessly do it again, but probably not as soon as if they were merely rebent. Talk to a good spring works - one that makes replacement springs for the trucking industry. Check Hemmings Motor News or your local yellow pages or truck stop. Good hunting! I'd have them rebent and retempered, were I you (if I couldn't locate replacement springs - here's another thought - J.C. Whitney in Chicago used to list the springs in their catalog - might have some still 'on the shelf', even though they're no longer listed in the catalog. Call or write to them!) - Larry Schear Twin Cam, Inc.

I have exactly the same problem and I am going to get my springs reset when salt goes on the roads. If they sag again, I'll try something else. - Bruce Cunningham, '53 XK120 OTS
