Which lower is that?

Mevotech CTXMS501184. It’s their aluminum arm with the TTX ball joint. Part number states it fits 14-18 Silverado/Sierras, 15-20 Yukon/tahoe/Esky.

No you can not just for the sole reason that would be entirely too easy compared to all the other hoops GM is making us jump through.

Moog (Mevotech) has an online Q&A section on their parts compatibility catalog. It’s usually a 24 hr turn around time when respond back.

If you do inquire be sure to include their part #’s and specifically ask if the ball joints between part #ABC and #123 are cross compatible.

If they’re not, what parts are for my 69 Camaro kinda language or you’ll get … sorry, need more info
