Peterbilt 352 Toggle Extensions

Frequently Asked Questions About Peterbilt 352 Toggle Extensions

What are toggle extensions and why do I need them for my Peterbilt 352?

Toggle extensions are switch extenders that mount onto your existing dash toggle switches, making them easier to reach and operate while driving. Many Peterbilt 352 drivers find the factory toggle switches sit too deep in the dash panel, requiring them to lean forward or take their eyes off the road. These extensions add 1-2 inches of length to your toggles, bringing the switches within comfortable reach and improving safety by keeping your attention on the road.

Will these toggle extensions fit my specific year Peterbilt 352?

Our toggle extensions are designed to fit Peterbilt 352 models from 1969 through 1989. They work with the standard 1/2-inch toggle switches found in these trucks. However, if your 352 has been retrofitted with non-standard switches or custom dash panels, we recommend measuring your existing toggle shaft diameter before ordering. The extensions require a minimum of 3/8-inch exposed toggle shaft length for proper installation.

How difficult is the installation process, and what tools do I need?

Installation is straightforward and typically takes 5-10 minutes per switch. Most toggle extensions use a simple set-screw design that requires only a small Allen wrench (usually included). No drilling, wiring, or dash removal is needed. Simply slide the extension over your existing toggle switch shaft, align it to your preferred position, and tighten the set screw. Some drivers apply a small amount of thread locker to prevent loosening from vibration.

What material and finish options are available, and which holds up best?

Toggle extensions come in three main materials: chrome-plated brass, polished aluminum, and anodized aluminum in various colors. Chrome-plated brass offers the best durability and resistance to wear from frequent use, though they cost slightly more. Polished aluminum provides a classic look but may show fingerprints and require occasional polishing. Anodized aluminum in black or colored finishes resists scratching and matches well with modern interior upgrades.

Can I use these extensions with lighted toggle switches?

Yes, most toggle extensions are hollow throughout their length, allowing LED or incandescent lighted toggles to shine through. However, the light intensity may be slightly reduced depending on the extension length and material. Chrome and polished aluminum extensions typically allow more light transmission than anodized versions. If maintaining maximum light visibility is crucial, we recommend choosing shorter extensions (1-inch rather than 2-inch) or clear acrylic options where available.
