Just to follow up with my last comment...I must put in a "Holy ****". My vague memory (it the second thing to go) was thinking the OEM lug nuts were in the $6.00ea range (and that's Canadian dollars). Well I thought I post the part number...so looked that up for my current 2018 RAM Sport 4x4. That number is " 6509422AA Nut-Wheel" . The price from Mopar Parts Canada...you better be sitting down, ... how's $17.00 ea thrill ya! And that's the before tax price.
I've now got three sets of these. Each set has various degree's of wear-n-tear on them. One set dates back to 2003. The second set to about 2009 when I put the SRT-10 wheels on the my SLT. The third set are the originals that came on the new 2018 Sport. Hmmmm, maybe I'll start using the aftermarket lugs that came with my Hellcat Replica wheels. Got two set of them also...one in chrome and one in gloss black.
Holy sheep dip..them OEM lugs are spendy!
I'd suggest yo google that part # and see where you might find your best price if your still intent on going OEM.
edit: here's a US price. About 10.00ea.
