I looked into replacing my rear shock on my 1990 sidecar unit late April. I contacted the distributor for Hagon in NA. They are located in Nova Scotia but also have a warehouse in Maine. They were very helpful in providing me with lots of info.
They can be contacted at the following address:

See below an extract from their reply... All $ figures are in CAD dollars. You would have to contact them to have the US prices!
Thanks for your interest in Hagon suspension for your motorcycle. No reason to have anything shipped to you from England when we have air freight shipments arriving in Nova Scotia all the time from the Hagon factory. . Normally I would invite you to visit us in Wolfville, but our parts pickup counter is closed due to the virus situation, and in any case, our prices include shipping to us from UK, post to your door from our warehouse, and all taxes.
I would like to confirm a TOTAL price to your door of CAN$672.75 for the Hagon M61105 Monoshock for your 1990 GL1500 SE Honda Gold Wing sidecar rig, and would check when I placed the order order to see if Hagon recommended going with a stiffer spring rate due to the sidecar. It would be helpful to get an idea of your weight and estimated load and percentage of time loaded, if possible.
If the factory feels it might be better for you to buy a pair of shocks instead, I will let you know, but as your compressor is working, I think you are best sticking to the original configuration. Pricing for twin shocks is as follows, though:
Standard Road Shocks with 3 position spring preload adjustment, black body/chrome or black spring ( stainless body available at additional cost) $343.85 pr. TOTAL
2810 series, also has 10 position damping adjustment $557.75 PR. total, ditto on stainless body
NITRO series, all stainless and alloy, factory rebuildable, has same damping adjustment as 2810 but infinite spring preload adjustments, $936.10 pr. TOTAL
All Hagon shocks come with a 2 year unlimited mileage warranty, and a spring adjustment tool.

I have not dealt with them yet but the Canadian store is located near where I live. They have a very good reputation among the community!
Cheers,
Hope this help...
