This listing is for a set of six shocks needed to replace all the shocks on a Jaguar XJ6 or XJ12 from 1971-1989.
The part numbers are as follows,
The two skinny long front ones are
26-1089
The four thick short ones for the rear are
30-1090
These are new old stock, they move as they should and do not show any signs of use.
Of the four rear shocks two are shiny and two have a greyed top metal part as you can see in the pictures.
Please make sure the part numbers above are for your vehicle. It's not a universal product for all the jags of those years.
