Are shims need for this lift?

Anyone notice on the TRD OR that there's already a 1* shim in the rear? I took mine out and replaced it with a 3* one.

 

That was added in 18 or so at some point. My 17 had none. Even my replacement leafs had none and that was done in early autumn of 18.

 

I had the same lift. Ditch the CB spacer and diff drop they are unnecessary. I used 2.5 degree shims then switched to 3 degree shims.

Both worked, but you will probably need the ECGS bushing if you get rumble vibes when braking through the 20mph range on deceleration. It replaces the POS driver side CV needle bearing

Hope this helps

 

Same here
