In early 2012 I ordered a full set (front & rear) Arnotts to replace the OEM shocks. (I did the four replacements myself...)
The rear right Arnott shock recently started losing pressure - which I did not expect so soon after the Arnott fitments - and I have now gone this route;

On comparison, I'm rather disappointed in the lack of a metal sleeve and rubber boot on the Arnotts! (Their new shocks now incorporate both boot & sleeve.)
If there are any forum members here who have at some stage replaced their shocks with Arnotts ±2012, check if your shocks have the metal sleeve & rubber boot. If not, you may be "walking my path" soon as well...
(I was seriously let down - and embarrassed - with these Arnotts, touring with 4 ladies!)
