Well, I believe I've came to a conclusion to either get a 3" BL or 4". I believe that's the correct name for the type I want. Some people call it a block kit I believe. Where you put some block type things under the leaf springs. Thank you for your help everyone.
From my experience, BL is traditionally an abbreviation for body lift. That is where you insert spacers between the frame of the truck and the body. I'm not quite sure on compatibility since I am working with a 1986 W250, but Performance Accessories offers a 2" body lift for around $150 (part number PER-612), and also a 3" body lift for around $95 (part number PER-613). However, many companies also offer a lift block kit similar to the one you mentioned. From my research, I found that both Skyjacker and Superlift offer a 2.5" kit, Superlift offers a 3.5" kit, and Skyjacker, Rough Country, and Tuff Country each offer a 4" block lift kit. Various companies then offer 5", 6", and 8" lifts, but you mentioned that you are interested in a smaller kit.
These manufacturers offer different types of lift kits and systems for different situations, and therefore they provide different parts. Please remember that this information is from my own research for my own application, so you should make sure that it is compatible to yours. Also, I have been working with the Ram trucks for only 2 days now, so if I am wrong about any of this, somebody please let me know!
