I can do 5100s no problem. I just didn't know what was preferred between preloading the front 5100s to get a .5-1" lift or by just doing spacers.
I installed a spring spacer on the bottom of the front springs. my 2016 runner has a driver side spring that is bigger diameter spring , then the pass side is a smaller diameter spring.
when new I filled the gas tank to 3/4 .. then the driver side drops down a bit.
I put 2 coil spacers on the right side and then put the larger spacer on the driver side. I lifted the runner 1 inch on the front ...the runner when the gas is around 1/2 of gas the runner is level and right /left the same height.
then I adjusted the toe adjustment .. toe is neg... factory OEM was a bit positive ... now my runner works great tires are perfect tread wear and when I hit the brakes the runner did not drop down when the brakes are working.
I paid 10 bucks ...................on the coil spring spacers
