Frequently Asked Questions About Kenworth Cabover Elbows, Piping & Comp.

What material are these elbows and pipes made from, and will they rust?

Our Kenworth cabover elbows and piping are typically manufactured from either 304 stainless steel or aluminized steel. The stainless steel options offer superior corrosion resistance and won't rust under normal conditions, making them ideal for harsh weather environments. Aluminized steel provides good heat resistance and moderate corrosion protection at a lower price point. Always check the product description for specific material information, as this varies by manufacturer and product line.

Which Kenworth cabover models and years are these parts compatible with?

These elbows and piping components are primarily designed for Kenworth K100, K100E, and W900A cabover models from the 1970s through 1990s. However, compatibility can vary based on engine type (CAT, Cummins, Detroit) and specific exhaust configurations. We recommend verifying your truck's model year and engine specifications before ordering. If you're unsure, contact our support team with your VIN number for exact fitment confirmation.

How difficult is the installation, and what tools do I need?

Installation typically requires intermediate mechanical skills and takes 2-4 hours depending on your experience level. Essential tools include a socket set, torque wrench, exhaust clamps, high-temperature exhaust sealant, and safety equipment. Some installations may require cutting or modification of existing pipes. Professional installation is recommended if you're not comfortable working with exhaust systems, as proper sealing and alignment are critical for performance and safety.

What's the difference between chrome, polished, and raw finish options?

Chrome-plated elbows offer the highest shine and durability but come at a premium price. They resist tarnishing and are easier to clean. Polished stainless steel provides excellent appearance without the maintenance requirements of chrome, though it may show fingerprints more easily. Raw or mill finish options are unpolished and ideal for those who prefer a workmanlike appearance or plan to paint or coat the pipes themselves. Chrome and polished options typically add 15-25% to the base price.

What size elbow or pipe diameter do I need for my Kenworth cabover?

Most Kenworth cabovers use either 5-inch or 6-inch diameter exhaust systems, with 5-inch being more common on older models and smaller engines. To determine your size, measure the outside diameter of your existing exhaust pipe where the new component will connect. If replacing multiple components, ensure all pieces match in diameter. Some turbocharged engines may require specific elbow angles (typically 45 or 90 degrees) for proper clearance. When in doubt, refer to your engine manufacturer's specifications or consult with our technical support team.
