Frequently Asked Questions About Kenworth W900A Toggle Extensions

What models and years are these toggle extensions compatible with?

These toggle extensions are specifically designed for Kenworth W900A models from 1961 to 1985. They will also fit W900B models (1982-1987) that share the same hood and grille configuration. However, they are not compatible with newer W900L or W900 models due to different mounting points and hood designs. Always verify your truck's model year and check that your hood has the correct mounting holes before ordering.

What material are these toggle extensions made from, and will they rust?

Our toggle extensions are manufactured from heavy-gauge steel with a chrome-plated or powder-coated finish, depending on the style you choose. The chrome versions feature triple-plated chrome over steel for maximum corrosion resistance. Powder-coated options use a thick, durable coating that resists chipping and fading. With proper care and regular cleaning, both finishes will maintain their appearance for years. We recommend applying a light coat of wax quarterly to chrome versions for optimal protection.

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

Installation typically takes 1-2 hours and requires basic hand tools including a socket set, wrenches, and a drill with metal bits. The extensions mount using existing holes in most cases, though some applications may require drilling 1-2 additional holes. Each set includes detailed instructions with diagrams. Common challenges include aligning the extensions properly with the hood latches - we recommend having a helper to hold the pieces in place during installation. Professional installation is not required but is available at most truck shops.

What styles and finishes are available?

We offer toggle extensions in three main styles: straight extensions (4-inch and 6-inch lengths), curved extensions with a classic swept-back design, and heavy-duty extensions with reinforced mounting brackets. Finish options include mirror-polished chrome, black powder coat, and bare steel for custom painting. The straight extensions are most popular for a classic look, while curved versions provide additional clearance for aftermarket air cleaners. All styles maintain the authentic W900A appearance.

Will these extensions affect my hood operation or cause alignment issues?

When properly installed, our toggle extensions will not interfere with normal hood operation. They are engineered to maintain the factory hood-to-latch alignment and closing pressure. Some customers report needing minor adjustments to their hood stops or rubber bumpers after installation to achieve perfect fitment. The extensions add approximately 2-3 pounds to each side of the hood, which is well within the design limits of the W900A hood hinges and should not cause sagging or premature wear.
