This week, a massive milestone: delivery of the Speedtech Performance ExtReme chassis. If you know your C10s, you know this is a serious piece of kit. Out goes the old-school leaf-spring setup, and in comes a full independent rear suspension, engineered for true performance. We’re talking track-day handling in a full-size pickup.
This isn’t just a suspension swap-it’s a complete DNA rewrite. The factory bones were never meant to handle the kind of power or precision we’re throwing at this thing. The Speedtech chassis gives us not just strength and rigidity, but the perfect platform for the next wave of high-performance parts.
The four-way adjustable QA1 MOD coil overs are installed. We’re dialing in the ride height, and mocking up the driveline components to ensure everything fits before final paint and finishing. Because when you’re dealing with this much power, everything-every weld, every bolt, every bracket-has to be right.
