The scratch-built frame was designed to be NHRA-approved and provides the truck with a lightweight base to build on. Rob's four-link system helps with the hard launches and is adjustable to the desired use. The truck sports a full frame, and the engine was moved back 5 percent for better weight distribution. All hard-launching chassis have an X-member for strength, but Rob's Frightning has a pass-through section for the street exhaust. The headers were also fabbed by Rob to hold the turbos symmetrically centered to the engine.
