The Rancho RS9000XL shock absorber comes with self-lubrication functionality, whereas the Bilstein 5100 does not have any self-lubrication functionality.
Pricing
Pricing is another important key consideration to keep in mind. The Rancho RS9000XL is slightly more expensive than the Bilstein 5100. The price difference can vary depending upon the store you are buying from.
