Frequently Asked Questions About Kenworth T300-T450 Grille Guards

Will this grille guard fit my specific Kenworth model year?

Our Kenworth T300-T450 grille guards are designed to fit T300, T330, T370, and T450 models from 2008 to present. However, minor variations exist between model years, particularly in headlight configurations and bumper mounting points. We recommend checking your VIN-specific details or contacting our support team with your truck's year and model number to ensure proper fitment before ordering.

What gauge steel are these grille guards made from, and will they rust?

Most of our T300-T450 grille guards are constructed from 14-gauge steel tubing with reinforced mounting brackets. All guards come with either a powder-coated finish or polished stainless steel option. The powder-coated models include a zinc primer base for rust prevention, while stainless steel options offer superior corrosion resistance. Regular washing and occasional touch-ups on powder-coated surfaces will maintain appearance and prevent rust in harsh conditions.

Can I install this myself, and what tools will I need?

Installation typically takes 2-3 hours with basic mechanical skills. You'll need a socket set (including 3/4" and 7/8" sockets), drill with metal bits, torque wrench, and potentially a second person for positioning. Most guards mount using existing frame holes, though some models require drilling 2-4 additional holes. Detailed instructions are included, and installation hardware comes pre-packaged with grade 8 bolts.

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

Our guards are engineered with proper spacing to maintain factory headlight coverage and beam patterns. The horizontal bar placement is specifically designed to avoid light obstruction. Regarding airflow, the open-tube design maintains approximately 85% of original airflow to your radiator and charge air cooler. We've tested these extensively, and normal operating temperatures remain unaffected even under heavy load conditions.

What's the difference between the Ali Arc, ProTec, and other styles you offer?

The Ali Arc features smooth, curved aluminum construction that's 40% lighter than steel options, ideal for weight-conscious applications. ProTec models use heavy-duty steel with additional vertical supports for maximum protection in severe-duty applications. Standard models offer a balance of protection and value with straight horizontal bars. Consider Ali Arc for highway use, ProTec for construction or logging applications, and standard models for general vocational use.
