Frequently Asked Questions About Kenworth T700 Grille Guards

Will a T700 grille guard fit my specific year model, and what about the T680?

Kenworth T700 grille guards are designed specifically for model years 2008-2019. Due to front-end design changes, T680 grille guards are not interchangeable with T700 models. When ordering, always verify your truck's exact year and model number, as minor mounting point variations can occur between early and late production years. Most manufacturers provide detailed fitment charts, but if you're unsure, contact us with your VIN for precise compatibility confirmation.

What's the difference between aluminum and steel grille guards, and which holds up better?

Steel grille guards typically weigh 150-200 pounds and offer maximum impact protection, but require regular maintenance to prevent rust, especially in salt-prone regions. Aluminum guards weigh 40-50% less (reducing front axle load), won't rust, and maintain their appearance longer with minimal care. However, aluminum can be more expensive and may bend rather than bounce back from significant impacts. For most over-the-road applications, aluminum provides the best balance of protection and longevity, while steel is preferred for severe-duty or off-road use.

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

Installation typically takes 2-4 hours with basic hand tools. You'll need a socket set (usually 3/4" and 7/8"), torque wrench, and potentially a drill for auxiliary light mounting. Most quality grille guards use existing frame mounting points and come with detailed instructions. The main challenges include aligning the guard properly (a second person helps significantly) and routing any electrical connections for integrated lights. Professional installation usually runs $200-400 if you prefer not to DIY.

Which finish options last longest, and how do they hold up to road chemicals?

Polished stainless steel and mirror-polished aluminum require the most maintenance but offer the classic chrome-like appearance. Powder-coated finishes in black or custom colors provide excellent corrosion resistance and hide minor scratches well, typically lasting 5-7 years before showing wear. Chrome-plated steel looks great initially but can peel or rust if the coating is compromised. For maximum durability with minimal maintenance, choose either powder-coated aluminum or brushed stainless steel finishes.

Do grille guards affect engine cooling or fuel economy?

Properly designed T700 grille guards have minimal impact on cooling when correctly installed with adequate clearance from the radiator. Most drivers report negligible effects on engine temperatures. Regarding fuel economy, expect a 0.1-0.3 MPG decrease due to added weight and slight aerodynamic changes. Heavy-duty steel guards with multiple light bars may impact economy more noticeably. Ensure at least 4-6 inches of clearance between the guard and radiator for optimal airflow.
