Hi Jon

 

Standard units for the period, used in most things

 

Moss quote part number 202388RH new & 202389LH new, they also quote uprated, Moss units are repro, not NOS (China ?)

 

Revington only sell reconditioned units on exchange with a surcharge

 

Ready supply, just be mindful of quality

I have not got model specific info but you may still find something useful in my blog post about Armstrong Dampers: http://vitessesteve.blogspot.co.uk/2015/09/armstrong-lever-dampers-explanation.html

The earlier live axle cars utilised DAS 9 type shock absorbers, whereas IRS cars used the physically larger DAS 10 type.

 

These two body types are common to all manner of cars, but (at the risk of stating the obvious) the internals are specific to an individual model of car in terms of valving, for example . . . . and of course the lever arm itself is specific to vehicle application.

 

There isn't a lot of point in trying to convert from one spec to another, as in converting an MG base unit to TR, unless the desired application is unusually difficult to find. It may not be too difficult for a reconditioner to amend the internal flow rates to suit, but he may well not have a ready supply of your preferred lever arms to hand !

 

There are several reconditioners around, some of whom seem to be a tad ambitious in their pricing, shall we say. Others take, in my view, a minimalist approach to the reconditioning process - I could do just as well on my own bench, and do.

 

Perhaps the most well regarded reconditioner within the TR community is Stevson, been around for donkey's years and unfailingly reliable and reasonable in my experience. Proper job sort of folks.

Usual disclaimers !

I (so we) have had contact from an organisation who claim to have experienced an increasing number of seriously over stiff Armstrong shocks recently fitted to TRs - so stiff that the splines are stripping with obvious concerns for chassis integrity. Is this a subject that already has wheels under it?

Thats why Stevsons will only uprate to 15% for road car use.
