    Correct! Chassis dimensions 34 5/8" front, 35 1/4" rear between eyes, same for lwb and swb. (which means you could probably even get away with interchanging front and rear, although the shackles would not set very well.

    These figures are for the 2a, but dimensions were unchanged from 86/107 up to the end of S3 production.

    I have a nearly new pair, but obviously too far away. I had them on my 2a SWB but they proved to soft for the hardtop and tools, and the trailers/caravans I tow. They'd probably work really well on a soft-top.
    I might use them when I build my Land-Rover camper trailer. Another pipe-dream...

    You 100% sure of those measurements. I am sure that rear springs are about 6" longer than fronts.

    People in the US have fitted rear springs on the front, but it means significantly lengthening the dumb irons and moving the front axle forward.

    FWIW Measurements for S1 springs in the manual are 36 1/4" Front and 48" Rear. These are the sizes with the spring flat. Interestingly rears on Fire Engine variants both SWB and LWB are 42".

    I've got the "two-stage" springs from a LWB 3 trayback under my SWB 2a. Simple bolt-in fit, shackles stand about 30 degrees past vertical under normal load. Ride well, though they still bottomed out when I had to tow 3000L airblast sprayer half-full!
    Long story...

    The figures quoted are from the chassis dimensions page 4-J and 5-J in Series 2 & 2a Workshop manual P/N 606408 - and I just checked again to make sure I had the figures right.

    G'day Folks

    The "Two Stage" springs are/were originally used for Station Wagons, as they were softer when lightly loaded and stiffened when loaded, from memory they were called 6 by 2's they were also fitted to traybacked utes on request.

    Numpty, if you want to recondition your own springs I could help you, as I did all mine when I got 172-484,"Aggie" they were spred by rust and I stripped them cleaned, chamfered, radiused, and painted with tar, been on 16 years now no problems,all done at home with angle grinder, and patience, they might also have been fitted and tightened without the bushes being allowed to settle that would stiffen the suspension and wear the bush rubber quickly.

    cheers

    Must be a misprint then.

    My father kept my IIA manuals, but my SIII manual (PN AKM3648) agrees 100% with Numpty's S1 manual. ALL front springs are 36.25", ALL rears are 48".

    Btw - if anyone is interested, spring rates are:

    SWB rear (11 leaf) - 166 lb/in
    LWB Station wagon - 270 lb/in (Uncle Ho - must have been 8 plus 2 - because that is what they are)
    LWB Heavy Duty (8-leaf) - 368 lb/in
    LWB Extra Heavy Duty (9-leaf) - 415 lb/in
