Very happy that you offer that product. I was able to score a pair of Bilstein 5165 (with remote reservoirs). Thanks to those sleeves, I could insert them in the bottom rubber bushing of the 5165s. They feel a bit small, but I’m glad I have sleeves to protect the rubber. I coated them inside and out with moly grease. Happy with my purchase. Thank you for thinking of the tinkerer and not forcing customers to buy shocks from you only like others vendors do.
