💪Core 4x4 Control Arms Question

[spanishmack]

I just received my Cruise series of a complete set of 8 Core 4x4 control arms. I had the install instructions before they arrived and the torque specifications for the jam nuts had 2 different sizes 1 1/2" and 1 5/8". So, I ordered a couple of crowfoot wrench heads for those sizes to be able to torque them to spec. The smaller jams nuts on the short control arms fit the 1 1/2", however the larger jam nuts on the remaining 6 arms are too large for the 1 5/8".

Anyone with these arms on here? And if so, do you know what size(s) I need for the larger jam nuts? Thanks in advance for any info.

(Worst case, I can just measure them, but they're still nicely shrink wrapped and I didn't want to peel them apart til I'm ready to put them on.)

Get a big efffing adjustable wrench from tractor supply and tighten as tight as you can, then paint mark em. Did that on my clayton arms and they haven't moved. Plus, that big adjustable will come in handy at some point later.

UPDATE: Tech from Core 4x4 reached out and said they were having supply chain issues getting 1 5/8" nuts so they've been using 1 7/8". Mystery solved.
