You can go either way, it makes little difference. The spacer route, is clean and simple to install. It retains the stock ride while giving you the added lift you want. If you go with say the D-25 skyjacker way, they provide you with longer springs that take the place of the stock ones, yes you get two look at red springs, but many say the ride is stiffer, I don't know. Which ever way you go you should change the stock shocks out for longer replacement ones. Don't wast your go money on Skyjacker's shocks they suck, so does the Rancho RS5000's. I would go with the Bil stein as the number one pick, but you are the decision maker, not me. Just remember, the kits that come with shocks usually come with cheap one's thats how they make their money.
I went the spacer route, it has worked well for me. I think it also serves as a noise suppressor by isolating the vibrations of everyday road use and noise Thur it's poly spacer. Just my thought.
I also installed a dual shock mount from Fabtech, they sell great stuff and this model fits all Dodge trucks. Most that lift there trucks do so for the cosmetic results, they want larger tires like you for the Off Road look. This is fine, many do that including me, just don't kid yourself into thinking you increased your trucks off road prowess with any of the cheap lifts we discussed. For real off road use, nothing I have seen can beat the T-Rex suspension. It uses real adjustable off road shocks to deliver a great off road ride. They non have a "leveling Kit" that they sell, it is not to be confused with their other true off road kits, this leveling kit does nothing more then replace the front spring with a longer unit, and add the OEM Bilstien shocks, a good kit but way more then it should be at 500. 00 dollars. For comparison, the ploy spacer is 130. 00 and two good Bilstien shocks are 70. 00 each, so for 270. 00 you can do the same thing. It's your call. Good luck
