AT4 Off road Performance option effect mileage?

[trogi]

Thinking of ordering the 2021 AT4 with the off road performance option. Does losing the front air dam and the 1" inch leveler in the front effect gas mileage. I know the v6 ZR2 drops to 16/18 where the Z71 is 18/24.

I have the same model - with no changes - 3900 mile - average 19 overall and 26 on the highway. Saw post warning to watch trans temp when removing the air dam.

I got my AT4 in Feb and it came with the air dam, which I removed after a few months. My mileage sucked before and it still sucks. Averaging 15.5, up to 20 on the highway. I towed ~5000 lbs for 500 miles up a 7000’ mountain in hot June weather with no issues. Transmission never got above the 150s.
