Frequently Asked Questions About Kenworth T600 Frame Crossmembers & Covers

What years and models of Kenworth T600 do these crossmembers fit?

Our frame crossmembers and covers are designed to fit Kenworth T600 models from 1985 through 2007. However, compatibility can vary based on your specific truck configuration, wheelbase, and whether you have a day cab or sleeper model. We recommend checking your truck's VIN and frame measurements before ordering, or contact our support team with your truck details for verification.

Are these crossmembers made of steel or aluminum, and which is better for my application?

We carry both steel and aluminum crossmembers. Steel crossmembers offer superior strength and are typically more affordable, making them ideal for heavy-duty applications and severe service conditions. Aluminum crossmembers are lighter weight, resist corrosion better, and are preferred for weight-sensitive applications or trucks operating in high-salt environments. Most owner-operators choose steel for durability, while fleets concerned with fuel economy often select aluminum.

Can I install these crossmembers myself, or do I need professional installation?

Installation difficulty depends on your mechanical experience and available tools. Basic crossmember replacement typically requires a floor jack, jack stands, impact wrench, and standard hand tools. The process involves supporting the frame, removing old hardware, and bolting in the new crossmember. Most experienced mechanics can complete the job in 2-4 hours. However, if you're replacing damaged crossmembers due to an accident or need to modify mounting points, professional installation is recommended to ensure proper frame alignment.

What's the difference between OEM and aftermarket crossmembers for my T600?

OEM crossmembers are exact factory replacements with guaranteed fit but come at a premium price. Our aftermarket options are manufactured to meet or exceed OEM specifications, often using the same grade materials and dimensions. The main differences are price (aftermarket typically costs 30-50% less) and availability (aftermarket parts are usually in stock while OEM may require ordering). Many aftermarket crossmembers also feature improved coatings or design enhancements based on common failure points in the original design.

Do crossmember covers actually protect against damage, or are they just cosmetic?

Crossmember covers serve both protective and aesthetic purposes. They shield the crossmember from road debris, salt spray, and impact damage from rocks or ice chunks, which can significantly extend the life of your frame components. In winter driving conditions, covers can prevent ice buildup that leads to corrosion. While they do improve the appearance of your undercarriage, the primary benefit is protection - especially important for trucks operating in harsh environments or on unpaved roads where debris strike is common.
