President Walker IV FCC — The Truck CB Radio Built for Professional Drivers The President Walker IV FCC is the newest generation of the legendary Walker line and the direct successor to the popular President Walker III. If you drove a rig in the last decade, you probably ran a Walker or knew someone who did — the Walker 3 became a truck CB standard for a reason. The Walker 4 keeps everything drivers loved and adds a modern feature set built for today's road. Professional drivers demand quality from their CB radios. Your CB is a lifeline on the road — for road conditions, weather warnings, convoy chatter, and reaching another driver when your phone won't pull signal. The President Walker IV FCC delivers on that with a rugged truck CB build wrapped around President's industry-leading receiver sensitivity. The Classic Truck CB Design Returns The President Walker IV FCC keeps the classic OEM truck CB form factor that drivers have relied on since CB radio first hit the trucking industry. Professional drivers and CB enthusiasts love this design because it drops cleanly into truck cubbies, factory radio cutouts, and overhead compartments in Peterbilt, Kenworth, Freightliner, Volvo, Mack, and International semi trucks. The Walker IV FCC also fits naturally in a trucker's hand like the previous Walker generations — a detail long-haul drivers will appreciate on hour ten.

President Walker IV FCC — Frequently Asked Questions Does the President Walker IV fit in a semi truck?Yes. The Walker IV is built to standard OEM truck sizing at 7.28" wide, 6.77" deep, and 2.20" tall.

If your prior CB was a Walker, Walker II, or Walker III, the Walker 4 will fit the same cutout. What's the difference between the Walker IV and Walker III?The Walker IV FCC is slightly larger than the Walker III, and the bigger case makes room for the new features: Glow Mode, Noise Reduction Circuit (NRC), dedicated P-Channels, SWR Protection, and the front USB-C charging port. Both radios are 40-channel AM/FM, both use the same OEM truck form factor, and both use President's high-sensitivity receiver. If you own a Walker III and love it, the Walker IV is a natural upgrade.
