    I'd go for YSS as a reasonable alternative but my ZL came with a pair of those cheapo piggyback shocks and to be honest they were no worse than the I remember of the originals.

    You would be better for originality to go for a good better "nick" second-hand pair from a dry State in the USA or even a drier Mediterranean Continental Europe country! Not sure how many models, ZL, EL, EN, VN, fitted this type of shock if the 250s and VN cruisers did, then there are more out there! Otherwise I am going to check whether Norman @ NJB shocks can rebuild them, if he can I will let u know!
    The original pattern is I think, is a copy of those fitted by Harley Davidson in the 70s & 80s!


    Cheers

    They are the closest I have seen last year I bought a Pair of NJB Ultimate Rear shocks for my Norton, with half-shrouds like the classic late 60s Early 70s racers & the cost me £198. So I suppose £238 isn't bad but "Free Shipping" is a phrase used in the "States" which usually only cover the States! Weirdly they do not list the UK as a Shipping Destination!

    Measures a pair of shocks not fitted as yet to the ZL600 & I make it 340 mm between the centres of the shock "eyes", which translates into imperial @ 13.385 inches! Which given = 2mm is around 13 1/2 inches. The progressive 412 is only supplied in 11" & 12" lengths are these eye to eye centre measurements? Those supplied by this firm in England @ 11" & 12 " would surely, make them to small! Are the shocks a shorter length on the bigger machines ? Confused .com.! Unless some adjustments are facilitated.

    Honda Shadow VT500C & the VT500 had the same rear shocks as the ZL 600! By KYB. I think some of the bigger Shadows may have compatible rear shocks to the Eliminator too, perhaps the ZL900/1000 models.

    I have a set of ZL900 shocks with Vulcan springs (750 I think) mounted on my 600. Works just fine and gives you the air adjustment. The Vulcan springs allow for the overall length to be shorter.

    Does this mean that when the shock is totally rebounded the spring can lose contact on one side?

    So a shorter spring length, reduces the shock length down to the 13 1/2 inches required for the 600. R.J. n' Harriminator, stated that the big bike shock are maybe half an inch longer, centre to centre. Lizzy measured 335 mm n' I measured 340 mm between centres so in Imperial that is roughly equivalent to 13 1/2 inches, a softer more compliant spring for a the lighter bike would work out better too. On the "Big bike shock U could maybe perhaps slightly reduce the amount of internal oil to facilitate the lower ZL 400 & ZL 600 kerb weights . You could be scientific about it too recording oil in cc's n' the bikes riding stance n' comfort through progressive, (no pun intended), volume adjustments!
