Talk to me about "taco lean"

10mm IIRC

 

I suppose that's small enough I could've missed it, I didn't measure. I think I'd note that kind of difference though.

Anyway, aside from that, back to fixing it...

 

I found out about Taco Lean on another thread and jumped at ordering a 1/4" spacer. This thread ended up being more informative however. There seems to be a large debate over a single 1/4" spacer on the LF, versus a 1/2 spacer on the LF and a 1/4" on the RF. The bit about the stock versus aftermarket springs I think may be the key.

I personally am hoping one spacer with my 5100s and stock springs cures my LF issues (tire rubs fender well, slider rubs body, LF sits little over a 1/4" lower than RF).

 

Is there any way to tell the difference when the springs are installed? (stamped identifier or colored marking)
My truck has pretty significant lean..I'm wondering if I got the springs mixed up when switching suspensions..
