RGM or AN Vernier Isolastic kits

I appreciate that a lot of the components which RGM sell are indeed from AN, does anyone know if the Vernier kits sold by RGM are from AN??
If not are the kits of an equal quality.
Thank you

Not sure, probably their own copies in stainless but I fitted the RGM rubber iso covers a while back, along with fork gaiters and both perished badly. Bought genuine AN replacements which have been much better so would choose theirs, and they tend to stand by their products if you have an obvious problem, in my case a faulty sprag and new cam followers with slight pits in brazing both replaced without hassle. Good people to deal with in my experience.
RGM wouldn,t refund the original delivery postage this year when I returned their faulty stainless 850 exhaust roses that fitted neither my old RH4 head or the new Fullauto.
Standard AN 850 roses fitted both perfectly.

The Iso rubbers I bought from RGM were hard and increased vibration (think 650cc Atlas). The AN rubbers were softer and significantly reduced vibration.

Not much fun doing the same job twice but I can claim to have first hand comparison data.

I have noticed that RGM offers softer rubbers as opposed to standard ones. Has anyone tried them? Im convinced that the the bonded later
adjustable type are harder than the original separate pieces.
...of course I could be quite wrong.

For the small difference in price, I'll be getting them from AN
Many thanks Gents

Be VERY SURE to check the mating surfaces for A) flatness, and B) surface finish. The stainless kit I got, was conical shaped, and record grooved finish. Which, will eat up the teflon washers.

I used the RGM kit along with their DT head steady with spring ... once getting Spring tension properly set .... Bike was transformed .... not sure buffers were softer type , positive they were softer than what came out though...

if RGM gets their iso rubber bits from Norvil, then you will be disappointed. ASK. get the AN bits, if not AN, shop elsewhere, Norvil has been reproducing poor replacement parts . do a search....

here for example; https://www.accessnorton.com/NortonCommando/norvil-iso-bushings.25315/

I've fitted RGM Iso kits and the rubber is definitely a soft compound, similar to the original buffers.

RGM do not deal with Norvil.

ive fitted the rgm venier isolastic kit 2 years and 4k miles ago. the threads have a lot of free play between the axle and the "ISOLASTIC ABUTMENT", so i am a little worried. although the the isolastic works perfect together with the dave taylor head steady. i donnot have any problems with vibrations.

the rubber caps are getting porous, which is really annoying considering the effort to change them.
