Will these dash knobs fit my specific International 4700 or 4900 model year?
Most aftermarket dash knobs for International 4700-4900 trucks are designed to fit models from 1989 through 2002. However, there were minor dashboard variations between early models (1989-1994) and later models (1995-2002). Always verify the knob shaft size and mounting style before ordering. Standard shaft sizes are typically 1/4 inch or 6mm, but some specialty controls may differ. If you're unsure, remove one of your existing knobs and measure the shaft diameter and length to ensure proper fitment.
What's the difference between OEM and aftermarket dash knobs in terms of quality?
OEM knobs are typically made from harder ABS plastic with UV stabilizers that resist fading and cracking over time. Aftermarket options vary widely - premium aftermarket knobs often use similar materials to OEM and can last just as long, while budget options may use softer plastics that can crack or fade within 1-2 years. Look for knobs specifically labeled as UV-resistant or made from automotive-grade ABS. Chrome-plated and billet aluminum options offer superior durability but cost more than plastic alternatives.
How difficult is it to replace dashboard knobs, and what tools do I need?
Replacing most International 4700-4900 dash knobs is straightforward and requires minimal tools. For push-on style knobs, you'll need a small flathead screwdriver or plastic trim tool to gently pry off the old knob. For set-screw style knobs, you'll need an Allen wrench (usually 1/8 inch or 3mm). The process typically takes 2-5 minutes per knob. Be careful not to force knobs off, as this can damage the control shaft. If a knob is stuck, apply penetrating oil around the base and let it sit for 10 minutes before attempting removal.
Are there different styles available, and which ones match the original interior?
Yes, dash knobs come in several styles including smooth round, fluted (with ridges), pointed indicator, and custom designs. Original International 4700-4900 trucks typically came with black plastic knobs featuring either smooth or lightly textured surfaces. For a factory-correct appearance, choose matte black ABS knobs. Popular upgrades include chrome-plated knobs for a classic look, colored knobs for custom interiors, and billet aluminum knobs for heavy-duty applications. Some knobs also feature backlit indicators for nighttime visibility.
Why do my dash knobs keep cracking or coming loose?
Cracking usually occurs due to UV exposure, extreme temperature changes, or poor material quality. Knobs on the driver's side often crack first due to increased sun exposure. To prevent this, choose UV-resistant materials and consider using dashboard protectant sprays. Loose knobs are typically caused by worn set screws, stripped threads, or expanded plastic from heat cycling. For push-on knobs that won't stay tight, wrap the shaft with a single layer of electrical tape for a tighter fit. For set-screw models, replace worn screws with slightly longer ones or apply a small amount of thread locker to keep them secure.
