Deaver +3 Deaver +2 SD HD it's all the idiots on here can say. If you don't call deaver and discuss your specific needs then you are taking risks with your ride and your money. There are very few people on this forum that know what they are talking about when it comes to suspension...problem is you don't know who they are. In my case...after talking with Deaver...I wound up with a custom spring pack and paid less than the standard +2 +3 sd hd pre packs. People on here don't even ask you how you drive your truck, what results you are expecting, how loaded you plan to be, do you tow or anything else that would weigh into the decision. The old "Hey I put HD +2's and love em" suggestion isn't worth the time it took to post it. Call Deaver and discuss all the ways you want to use your truck, the kind of ride you are looking for and make sure you get a setup that fits your person needs. Take the brand suggestions on here for Deaver or Icon and ignore the rest of it. When you talk to Deaver or Icon make sure you speak with a tech and not the front end sales person unless they are a qualified suspension expert. Talking to the front end sales person will get you nowhere good.
