Why Buy Kenworth T800 Parts From 4 State Trucks?

Frequently Asked Questions About Kenworth T800 Parts

What years are your Kenworth T800 parts compatible with, and how do I verify fitment for my specific truck?

Our Kenworth T800 parts are designed to fit models from 1987 through 2014, though specific compatibility varies by part. To verify fitment, check your truck's OEM plate located on the driver's side door jamb and note your exact model year and configuration (hood length, axle configuration). For bumpers and exterior parts, also note whether you have a set-forward or set-back front axle. When in doubt, contact our support team with your OEM and we'll confirm compatibility before you order.

Are your T800 bumpers made from chrome-plated steel or stainless steel, and what's the difference in durability?

We offer both chrome-plated steel and polished stainless steel bumpers for the T800. Chrome-plated bumpers provide an excellent mirror finish at a lower price point but require regular maintenance to prevent rust, especially in areas with road salt. Stainless steel bumpers cost more initially but resist corrosion without special care and maintain their appearance longer. For trucks operating in harsh weather conditions or coastal areas, we recommend stainless steel for its superior longevity.

Do I need to drill new holes or make modifications to install replacement bumpers and grilles on my T800?

Most of our T800 replacement bumpers and grilles are designed as direct bolt-on replacements using existing mounting points. However, if you're upgrading from a standard bumper to a heavy-duty or custom style, some drilling may be required. Each product page specifies whether modifications are needed. Basic installation typically requires standard hand tools and takes 2-4 hours. We include detailed instructions with each part, and mounting hardware is included unless otherwise noted.

What's the difference between OEM-style and aftermarket T800 parts in terms of fit and quality?

OEM-style parts are manufactured to match original Kenworth specifications exactly, ensuring precise fit and finish. Aftermarket options often provide enhanced features like heavier gauge steel, additional chrome plating layers, or improved mounting systems. Both meet DOT requirements where applicable. Aftermarket parts typically offer better value and may include upgrades like pre-drilled light holes or reinforced mounting brackets that weren't available on original equipment.

Can I install T800 parts myself, or should I have a shop do it? What special tools are required?

Many T800 parts like mirror brackets, grab handles, and smaller accessories can be installed with basic tools in your own shop. Larger components like bumpers, hoods, and fenders are manageable with two people and standard tools including socket sets, wrenches, and a drill. You'll need a torque wrench for critical fasteners. Professional installation is recommended for air ride suspensions, complete exhaust systems, or if you're uncomfortable working with heavy components. Always support heavy parts properly during installation to prevent injury or damage.
