Be blxxdy carefull with these repros! The damper spindle on the genuine shocks passes into the top trunnion and is secured with a grovver pin, this is blxxdy important given the forces involved and prevents the two separating. On all of the repros I have seen the grovver pin isn't present so your relying on the strength of the thread (Steel in to an alloy, not the strongest combination)

You could always install a grovver pin..

Heed the words of Mr Dog - I had one of those repros seperate on me within 500 mls of fitment - not funny.

Fortunately I had knocked up a shox compressor jig for a previous resto so I was able to investigate and remedy. I found the damper rod does have a lock nut to prevent it unscrewing out of the trunnion - trouble is you have to trust this has been tightened by our diligent Chinese friends - mine wasn't :shock:

I reassembled the unit with plenty of locktite and as much torque on the locknut as I dared use. Touch wood, it's been fine

Sorry no - it wasn't really part of a resto so I wasn't keeping a photographic record.
If anyone's interested, I'm happy to post pics of the spring compressing jig I made? It's just two 12mm ply plates with holes machined:
Plate 1. fits over the the trunnion and butts up againist the top face of the plastic shroud
Plate 2. fits over the lower shock body and butts up against the lower spring retaining ring. The plates are held together with four M12 studs cut to length.
Tightening down the 4 nuts on the studding against the top plate compresses the spring evenly and safely so you can gain access to the area beneath the plastic upper shroud.
Only took a couple of hours to knock up but reete handy.
Infact it was quicker to make it than describe it :blah
