What the difference between TSB and non-TSB springs?
Sorry I’m new.
Have a ‘21 Lunar Rock 4Runner and would like to get some more height with Eibach springs so I can fit 285s on there without a body Mount chop.

Mattolie is correct
be sure that you note that the TSB only applies to PRO trim 19-20 models.
You have a 21, so if it is a PRO, then you need need the after TSB model or a model designated specifically for the 21.
If is not a PRO, then none of this applies.
