I am needing to order cam phasers for my vehicle listed above LTZ model. My problem is not knowing exactly which ones to order. I get my parts from Rock Auto, but I only see 3 of the 4 needed. What am I missing? Do I order 2 of the exhaust?

Welcome to 2CarPros.

There is one for each cam, so there should be 4. I would recommend contacting them to confirm the exhaust actuator they are selling works for either side. As far as the timing chains, here are the directions specific to your vehicle:
