TRD OEM Bilsteins info needed

This is really just sort of an academic question:

How far back in model years will the OEM TRD Bilsteins off of an '09 fit earlier TRD OR with no modification ?

AND

Will those same Bilsteins swap onto any other non-TRD of any model year ??

Just curious; not for me, as I am set with 5100's all around and have no intension of going back, just wondering.

 

They will fit any 2nd Gen 6 Lug Tacoma.

 

No earlier.

 

Shocks from '05-'09 are interchangeable, but only if you're referring to 6 lug trucks meaning only shocks from 6 lug trucks will fit other 6 lug trucks and 5 lug trucks to 5 lug trucks.
