Powdercoating would give the best, most durable and long lasting results. But most (maybe all) powdercoating shops want the items completely disassembled and they clean and bead blast them before powdercoating. Also the parts have either a + or - electrical current applied to them so the powder coating with the opposite charge can be attracted and applies to the part.
The powdercoating oven curing temperature is around 400F so any oils or fluids might give off gasses that could contaminate the powdercoating application and ruin the job.
Also if you have been using these shocks for 10 years and had no issues, any beadblasting and 400F temperatures in a curing oven might cause seals etc., to fail. maybe you can't find replacement parts now. Better check first.
You could paint the parts yourself but this would give the least durable results and not look as good as powdercoating or a professional paint job.
Having a good paint shop do a nice epoxy coating is probably your best option.
