The Kenworth W900 isn't just a truck — it's a statement. With its long nose, vertical air intakes, and timeless design, it represents the heart of the American trucking industry. But for all its beauty and power, the W900 has a problem that nearly every owner-operator knows about: hood chirp.
Why the W900 Chirps More Than Most
The W900's hood is longer and heavier than most. That means:

The pattern is the same every time: temporary relief, followed by the squeak returning worse than before.
The Kenworth-Specific Solution: Hood Skinz KW
Hood Skinz makes a dedicated KW line specifically for Kenworth hood bumpers. These low-friction sleeves slide directly over your factory rubber bumpers and replace the rubber-on-metal contact with a smooth, low-friction surface. The chirp stops instantly.
Installing a set of KW Hood Skinz takes about 30 seconds per bumper. No tools, no drilling, no adhesive. They're consumable armor — a wear item designed to be replaced periodically, just like every other consumable on your truck. When they wear out, swap in a fresh set and stay silent. Backed by our 45-day squeak-free guarantee.
The KW line fits the W900, W900L, W900B, T800, T660, T600, and T2000 — all the classic and aero models that use the K179-528 bumper.
