I unfortunately have needed to replace my rear shock twice now. First one at 45k and funnily enough the second at 90k. I contacted several specialist shock repair outfits all of which told me the electric trophy shocks can't be repaired. Well for those who end up in a similar situation I can fully recommend FIREFOX RACING LTD from Keighley. Great job done and despite mine needing replacement piston rod due to corrosion still well less than half new price including dhl collection/delivery. Find them on google. Brilliant service.
