Took me a long time and asking a lot off people to measure springs but found these up on eBay And thay are from MARZOCCHI 888 RC2X WC 203mm 06-07 Had to do some work as thay are narrower to the plastic slider that fits inside the spring to keep it inline and also it was about 25-30 mm shorted but I had a spare spring spacer and had to cut that and fit at the bottom of spring to make it the correct length all works perfect get full 190 travel and it loose so much weight both springs are about the weight of 1 steel spring

 how do you fit the ti spring in there?
what spring you use?

normaly only the original springs are fit on the cartridges...
