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

We carry high-quality aftermarket alternatives. 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, 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. However, any damage caused by improper installation could affect coverage for that specific area. Keep original parts if possible - some buyers prefer stock configuration. Document all upgrades with receipts to show prospective buyers the investment in quality parts.
