Frequently Asked Questions About Kenworth T660 Grille Guards

Will these grille guards fit my specific year Kenworth T660?

Most grille guards for the Kenworth T660 are designed to fit model years 2008-2020. However, there can be slight variations between early models (2008-2012) and later models (2013-2020) due to minor front-end design changes. Always verify the specific year compatibility listed in the product description, and if you have a 2008-2012 model, double-check that the mounting brackets align with your truck's frame rail spacing. When in doubt, contact us with your VIN number for exact fitment confirmation.

What's the difference between aluminum and steel grille guards, and which should I choose?

Steel grille guards typically weigh 150-200 pounds and offer maximum protection but may require touch-ups over time to prevent rust, even with powder coating. Aluminum guards weigh about 40-50% less (usually 75-100 pounds), won't rust, and are easier on your front suspension, but they're generally 20-30% more expensive. If you're running heavy hauls or frequently encounter wildlife, steel provides better impact protection. For long-haul drivers concerned about weight and fuel economy, aluminum is the better choice.

Can I install a grille guard myself, or do I need professional installation?

Installation typically takes 2-4 hours and requires basic tools including a socket set, torque wrench, and possibly a drill for certain models. Most grille guards use existing frame mounting points, but some may require drilling 2-4 additional holes. You'll need a helper to position the guard during installation due to the weight. The most challenging part is usually aligning the mounting brackets while supporting the guard's weight. If you're comfortable with basic mechanical work and have a helper, DIY installation is feasible. Professional installation typically costs $200-400.

Will adding a grille guard affect my headlight beam pattern or block airflow to my radiator?

Quality grille guards are designed with proper clearance to avoid interfering with headlight beams - typically maintaining at least 2-3 inches of space from the headlight lens. However, some auxiliary light mounting positions can create glare if not properly adjusted. Regarding airflow, most guards reduce radiator airflow by only 5-10% due to their open design. In extreme heat conditions or when pulling heavy loads, monitor your temperature gauge for the first few weeks after installation to ensure cooling isn't compromised.

What finish options last the longest, and how do I maintain them?

Chrome-plated steel offers the classic look but requires regular polishing (monthly) and can show pitting after 2-3 years in harsh conditions. Powder-coated finishes in black or custom colors typically last 5-7 years with minimal maintenance - just wash with soap and water. Polished aluminum maintains its appearance with less frequent polishing (every 2-3 months) and won't rust, but can oxidize if neglected. For the lowest maintenance, choose powder-coated steel or aluminum. Avoid automatic truck washes with harsh chemicals, as they can damage any finish over time.
