No, the Skid Factory guys are "social media" gurus who provide entertainment and merchandise, as well as doing "projects".
The 4WD upgrade business is big business here, and the companies doing that line of work concentrate on upgrades to everything from chassis' to axles, suspensions, engines, fuelling, interiors, lighting, etc.
Most of the companies just specialise in a few related lines of upgrade, such as suspension and chassis, or fuel injection. Most are starting to realise the benefit of having a "social media" presence and making a few videos for entertainment to boost their business - but many of them simply rely on regular large customers such as mining companies, who spend like drunken sailors.
The Skid Factory guys are simply largely intent on the money-making potential of global entertainment, it blows a lot of people away when you see "influencers" make millions overnight, just producing video entertainment, often with little real value. Kind of like the crap entertainment videos on Farcebook that string you along with a drawn-out storyline, that is just straight-out time-wasting.
