Why Choose Kenworth Aftermarket Parts vs. OEM?

You get more choices, lower prices, and greater in-stock availability than traditional OEM Kenworth parts. You can easily find model-specific, direct-fit replacement parts for your big rig, whether you need Kenworth W900 replacement truck parts or Kenworth t680 accessories.

Frequently Asked Questions About Kenworth Semi Truck Parts

What year models and specific Kenworth trucks do your parts fit?

Our Kenworth parts cover models from 1985 to current year, including T680, T880, W900, T800, T600, T660, and T700 series. Each product listing includes specific year ranges and model compatibility in the description. For example, our chrome bumpers typically fit W900L models from 2003-2024, while T680 parts generally cover 2013-present. Always check the product description for your exact model and year, or contact our support team with your OEM for verification.

Are your Kenworth parts OEM or aftermarket, and what's the quality difference?

We carry both genuine OEM Kenworth parts and high-quality aftermarket alternatives. OEM parts are manufactured to Kenworth's exact specifications and typically cost 30-50% more. Our aftermarket parts come from trusted manufacturers like Valley Chrome, Roadworks, and Jones Performance, meeting or exceeding OEM standards. Aftermarket options often provide better value with comparable durability - many include enhanced features like triple chrome plating or reinforced mounting brackets not found in stock parts.

What tools and time are required for installing bumpers, grilles, and exterior parts?

Most exterior installations require basic hand tools: socket sets (typically 1/2" to 3/4"), wrenches, and a torque wrench. Bumper installations usually take 2-4 hours with two people - the weight requires assistance. Grille replacements average 1-2 hours. Hood mirrors and smaller accessories install in 30-60 minutes. Complex items like full aero kits or custom light bars may need drilling and wiring, adding 2-3 hours. We include installation hardware with most parts, though some applications require reusing existing brackets.

Do chrome parts require special maintenance, and how long do different finishes last?

Chrome parts need regular cleaning with chrome polish every 2-4 weeks to prevent pitting and rust, especially in winter climates with road salt. Our triple-chrome plated parts typically maintain their shine for 5-7 years with proper care. Powder-coated black parts last 8-10 years and only need soap and water cleaning. Stainless steel options offer the longest lifespan at 10+ years with minimal maintenance. Avoid harsh chemicals and always dry chrome thoroughly after washing to maximize longevity.

Will aftermarket parts void my Kenworth warranty or affect resale value?

Aftermarket exterior parts like bumpers, grilles, and mirrors do not void your Kenworth powertrain or chassis warranty under the Magnuson-Moss Warranty Act. However, any damage caused by improper installation could affect coverage for that specific area. For resale value, quality chrome and stainless upgrades often increase truck value by $2,000-5,000 when well-maintained. Keep original parts if possible - some buyers prefer stock configuration. Document all upgrades with receipts to show prospective buyers the investment in quality parts.
