Do you sell the rear shocks? I see the separate spring kit but no shocks with it. Thanks

• Which SKU is needed to compliment this kit if we want four front shocks? general
• I see a lot of kits come with Urethan joints. Are there also rubber substitutes? I believe they take a good bit a vibr general
• Is this Bilstein kit available in a quad shock arrangement? If so, what other part numbers would be needed? Thank you general
