Toytec Rear Shim to fix Tundra lean

Hello Everyone! My '13 Tundra with Procomp 6" stage 2 lift has a driver side lean of about 1/2". I have front coilovers that I have adjusted to level out the lean. The front end measurements are about even now after the adjustment but the rear end still dips about 1/4-1/2 " on the driver side. No accidents with the truck, I have had it since new. Will the Toytec rear shim work to correct this driver side lean? If so can I just put the rear shim on the driver side or would I have to put one on the passenger side as well?. Thanks for your help!

 

How much gas was in your tank when you measured?

 

3/4 tank of gas

 

@Coachbuilder1 has shims for the front coil overs to correct that. Stock coilovers compensate for that. Which is why they are labeled on the truck.
