Sanji uses his Armament whenever he used DJ. Gear 4 would be mostly related to Hells Memories since both involve fully coating his body with Haki and then using his unique ability. Gear 5 is more akin to IJ since it involved a latent ability he’s always had awakening that he then coats in haki.
Zoro doesn’t have an equivalent since he doesn’t have a transformative or physical boosting ability. Zoro just pumps out more and more haki but his body remains the same.
