RE 4" vs RE 4.5" Extreme

What is the difference between these two (besides 1/2 inch )? The 4" comes with shocks (cheap?) but not shackles for $820, the 4.5 EX comes with shackles but not shocks for $1129. Are the regular RE springs by another company (cheaper)? Are the Extreme springs that much better?
I really prefer Bilstein shocks so I'm leaning towards the 4.5 EX. I know the general opinion is to piece out, but I've been looking at piecing both the BDS and RE and the kits seem cheaper even if I won't use some of the parts.

The extreme duty springs are the 1454 up front and are desirable. I beat mine like a red headed step child.

Unless you NEED the whole kit, just buy the spring separately get Beserk shackles , and your Bilstien shocks... had them last time I checked.

Pretty much what I did. I have the 4" springs and work them hard with no ill effects..

I got the 4in kit to save the hassle of piecing things together because i had limited time to get it done and have been happy with my decision. Rides very nice. Although, i would recommend anticanman's brake line extension mod or some nice full extension braided lines, nix the hard line extension you get with the kit, and get a Slip yoke eliminator(which should be done with most lifts this size). Shackles can be had for cheap through Beserk
