If the Fourth Hokage was known to be the strongest shinobi in Konoha because of his capability to seal the powerful Kyuubi into Naruto’s body, then you are wondering how the Third Kazekage became the most powerful shinobi in the Hidden Village of the Sand.
This question is actually answered at the fused episodes of 22 and 23 by Chiyo-Baasama.
According to Chiyo-Baasama, the Third Kazekage has the most feared weapon in the history of the hidden village of the Sand.
If Gaara has the chakra molded sand, the Third Kazekage also has the iron sand. The technique using the iron sand was invented by the Third Kazekage by himself. The iron sand will be molded into different forms and can be used as weapons and at the same time as defense.
How the Third Kazekage did it?
The Third Kazekage like Gaara has an earth element chakra. But he has the ability to change his chakra into magnetic field. Thus the iron sand will go with the Third chakra form.

Since the third kazekage was Gaara’s father, in the later mangas ,Gaara acquires the iron sand jutsus, not hosting Shukaku’s sand spirit

Later,as fifth kazekage,Gaara also acquires Shukaku’s wind style and chakra.
