Frequently Asked Questions About Kenworth W900B/W900L Air Tanks, Wraps & Mounting

What are the exact model year compatibility ranges for W900B vs W900L air tanks?

W900B air tanks are compatible with models from 1987 to 2007, while W900L tanks fit models from 1990 to present. The main difference is the frame rail spacing - W900B models have a narrower frame (34" standard) while W900L models have a wider frame (34.5" to 42"). Always verify your specific frame measurements before ordering, as some custom configurations may vary.

What material options are available and which holds up best against road salt and corrosion?

We offer three main materials: aluminum (lightweight, good corrosion resistance), steel (heavy-duty, requires maintenance), and stainless steel (premium corrosion resistance, no maintenance). For trucks operating in salt-heavy regions, stainless steel tanks provide the best long-term value despite higher upfront cost. Aluminum tanks offer good resistance but may show pitting over time. Steel tanks require regular inspection and coating maintenance to prevent rust.

Do I need special brackets or modifications to mount aftermarket air tanks?

Most aftermarket tanks use the existing factory mounting points and brackets. However, if you're upgrading tank size or switching from steel to aluminum, you may need new mounting straps (typically 24" or 26" depending on tank diameter). Some installations require relocating air lines or electrical components. We recommend purchasing a complete mounting kit that includes straps, bolts, and rubber isolators to ensure proper fitment.

What's the difference between polished, chrome, and powder-coated tank wraps?

Polished stainless wraps require regular maintenance but never rust or peel. Chrome-plated wraps provide the brightest mirror finish but can chip or peel if damaged, especially on lower-quality versions. Powder-coated wraps offer the most color options and durability against chips but may fade over time with UV exposure. For show trucks, chrome or polished stainless are preferred. For working trucks, powder-coated or brushed stainless provide the best durability.

Can I install air tanks and wraps myself, or do I need professional installation?

Installation typically takes 2-4 hours for experienced mechanics. Basic hand tools, jack stands, and proper safety equipment are required. The most challenging aspects are safely supporting the tank weight during installation and properly routing air lines to avoid kinks or heat damage. While many owner-operators successfully complete this installation, first-timers should budget extra time and have a helper available. Professional installation typically costs $200-400 depending on complexity.
