King 2.5 rear shock question

I currently have dobinsons front and rear with the 2 inch lift dobinsons leafs. I’m being told I don’t need the 121ext model of
King rear shock that the 121 will work as well on this set up. Does anyone have any insight on this?

 

We hardly ever recommend, or even sell the standard length -121. Reason being, they share the same compressed length as the extended travel but the -EXT has slightly more travel. The EXT shock has about .27" more travel. However, if you were looking to buy new shocks all together, we would suggest going with our converted Tundra rear shock for not much more $$ but gain 1" more of travel.
