Wider, higher rolling resistance tires. Provided 1.5” lift. The spacer provides 2” lift. I’m guessing each part contributes 50% of range reduction.
I agree that lifted with stock tires is not ideal look.
Front is 3” lower than rear. I put in a 2” spacers so now 1” lower in front. With weight in bed or trailer weight the vehicle would be level. 1” spacer will reduce rake some. Not sure if the part is available.
