    Hi guys,

    First time posting here so please bare with me. I have a 2019 Tundra and I have the CB shackles +3 already installed in my truck. My question is does anyone have the combination of CB shackles and the Deaver U748 leaf packs installed on there ride. I know most run TC or Camburg but I really don't want to buy another set of shackles if possible but if it is not compatible or safe than I guess I have to. So any help would be appreciated. Thank you in advance.

    I am putting together my list right now and Deaver U748’s are on it. Not sure if you already figured it out but one place I am looking is MCM Fab and when you buy the springs they come with new shackles. Hope that helps. Good luck!

    What negative effects? I haven't ever read anything about them negatively.... except maybe issues with mounting a 35 tire underneath(yes, I know it's possible).

    Hey guys thanks for the reply. I ended up using the +3 CB and deavers u748. I spoke to David owner of CB and he said was compatible. I still have mix feelings but so far it looks fine haven't driven the truck yet since I am waiting to install my metal bumpers. I bought my leaf springs from Headstrong offroad and they drop ship from Deavers them self and they do not come with shackles. So far I only know MCM sells them with there shackles.

    From the link I posted MCM (from MCM Fab) said:
    "The deaver advertised lift is based around using a shackle that is 1.25" longer than stock, which is roughly a 3/4" shackle. Any of the longer shackles will cause the leaf springs to have more negative arch, it alters the spring rate of the leafs, and can cause other issue. I do not recommend running any of the +2 or +3 shackles with the deavers. The deavers require a longer than stock shackle though as the main leaf is longer than stock, so you can not run the stock shackles with the deavers."

    This is something that you have to look into with any suspension modification. It's hard to bend your leaf springs negatively if you have your bumps set properly.
