5th Generation 4Runner rear spacer comparison between a common 1.5” metal spacer and Rancho RS70080 1.5” poly spacer. The specs for the Rancho RS70080 advertise 1”, but it will lift 1.5”. I have a 2017 4Runner TRD OffRoad with a ProComp 65205 2.25” front spacer lift. I chose the lift 1.5” in the rear with the 2.25” front so that my rear would be 1” higher than the front....and that’s exactly what I accomplished.
