    Default Rear Leafs Compared To Lift Blocks

    What are the pro's and cons of the two. Thinking about ditching the lift blocks for a new set of Deaver Leaf springs. Already running air bags if it makes a difference

    I believe that blocks are used for the sole reason of being cheaper to gain height, maybe a little better ride. Deavers are great springs and should be a progressive style spring, imo springs are the way to go you may suffer a little ride quality though. Just make sure you are running a good shock. (Bilstien)

    I went from blocks to springs and air bags in my old 04 GMC HD and the ride was way better than the blocks also a lot more safer when towing. I went with atlas springs though I liked them never had a problem with them. I also had bilstein 7100"s in the back.

    Deavers are the way to go.They are local and their customer service is great too. Jeff has always taken care of me....even re-arched a set of springs for free when I changed my front lift set-up. is Atlas and Deaver are really the same springs...they both buy the same materials.

    7100 are a good shock but if you're gonna spend that much go ahead and get some Fox bypass shocks so you can really dial in the ride. If not stick with the 5100's unless you are getting the 7100's for $150 or less each.

    Just my $.02,

    Hey mock thanks for the info. One other question would be will the Deaver 6inch rear spring be too much for a RCD 6inch lift kit? Also were is the best place to get the best deals on the shocks sounds like you got the inside tip!!!!

    I remember running a 4" lifted Deaver spring in the rear on my 6" RCD to get a level ride. Since you have bags already that will work. 6" spring is what I ran on my 6" CST lift that was cranked up to a true 6" of lift, might stinkbug your truck with the RCD. Just be sure to let them know what lift you have and they are good at matching it. Deaver sells all the shocks if you are buying direct from them, Jeff or Scott should take care of. If not you can call Jason or Bret over at Rancho Motorsports 909-390-9722. Tell them I sent you and they'll hook you up, Jason is the owner. Let me know when you call him and I'll give him a buzz and make sure you get the PB deal.

    BTW $500 for Deavers is a good deal...I've paid from $450 to $600 for them in the past.

    Hope that helps....if not PM me and I'll see what I can help with,
    Chris

    yeah i am worried about the 6inch deavers stink bugging the truck i have the bars cranked in the front also but dont know if thats going to be enough with the deavers in the back. 500 is a good deal thats why i want to buy them. Wonder if I could pull a leaf out to make them more of a 4 inch or 5 ich pack. might have to call deaver on this one. THanks for your help mock.

    hey guys i work at central 4 wheel drive in sacramento ca. i have been lifting trucks for about ten years now. a lift spring with an arch is NOT the way to lift your truck if you plan on towing something you will turn your 3/4 ton or 1 ton into a half ton. you want to stay with your stock springs add a tracktion bar if you feel the need. any arched spring WILL sag out . adding blocks WILL NOT change the ride of your truck!! if you have any questions about this you can call me at 916 481 7842 just ask for jerry

    What sort of truck is this for? Without knowing the exact truck specs most everything should be taken with a grain or two of salt.

    For the sake of the thread I'll assume this is a GM truck we are talking about. And if it's a GM 2500HD the following information is correct. The factory leaf spring pack has very little arch and the overload leaf hits the main pack after less than 2" inches of delflection. That is why the rear of these trucks ride so stiff. Once the main spring hits the overload spring the spring rate triples and the best shock in the world won't be any help because it's now become a spring issue. Replacing the factory spring on a 2500HD with a lift spring (more arch) can do wonders for the ride quality. The main reason for the ride improvement is because there is no overload leaf. That's the downside too... if you tow or haul heavy with the truck you'll need a set of airbags (long travel preferred) because the aftermarket spring will deflect under the load and cause the tail of the truck to squat way past level. That's bad for handling and can lead to porpoising (constant up and down motion) after hitting a dip or rise in the road. The long travel air bag design is good for about 12" inches of wheel travel and works good on and off-road. A 12" travel bag is usually sufficient for most HD's with custom rear spring packs utilizing stock shock mounts and stock length shackles.

    I have no idea how or why traction bars got brought into this discussion.

    The regular off-the-shelf Deaver Springs are made by Triangle Spring. Deaver designs the pack, tests them, tweaks them, then Triangle builds them and slaps a Deaver sticker on them. If you live near Santa Ana (or are willing to drive) buying a Deaver spring makes good sense as they can service the spring and sometimes "adjust" the height for you at little to no cost.
