I noticed alot of suspension bolts have those ridges in them that are along the bolt, that usually pass through a bushing. But I bought a sway bar setup and got some smooth bolts that connect the shock fork to the lca. Is this how they usually are or should they have ridges too.

 

Yeah that bolt that goes through the LCA does not have those "ridges" you are referring to.

 

Just be sure to put anti-seize on the smooth or ridged part and you shouldn't ever have any trouble removing the bolts in the future...
