Mod Trouble with only certain items

[ricksmith97]

Hey, I just downloaded the full game a couple of days ago and started to install some mods, I got the current OEM bike pack that works fine, got an FXR gear pack that works fine, however, I tried to install the helmet model and paint with no luck, in correct folder just does not appear in game, same with multiple boot packs of tech 10's. Any insight would be appreciated. Using WINRAR and putting items in what I believe to be the correct folders.

Link to the helmet model so we can test it to confirm it works.
