Frequently Asked Questions About International LT Sleeper Roof Accessories

What International LT model years are these roof accessories compatible with?

Our International LT sleeper roof accessories are designed to fit 2017 and newer International LT models with sleeper cabs. Most accessories are compatible with both the 56-inch and 73-inch sleeper configurations. However, some items like roof fairings and specific light bars may have different part numbers for each sleeper size. Always check the product description for your specific year and sleeper configuration, or contact our support team with your VIN for exact fitment verification.

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

Installation difficulty varies by accessory type. Light bars and marker lights typically require basic hand tools and 1-2 hours of installation time. Most accessories use existing mounting points or require minimal drilling with provided templates. You'll generally need a drill with metal bits, socket set, wire crimpers, and electrical connectors. Roof fairings and larger accessories may require two people and 3-4 hours. Professional installation is recommended for air horns and complex electrical accessories to maintain warranty coverage.

Are these accessories made from stainless steel or chrome-plated steel?

Material composition varies by product line and manufacturer. Premium accessories like Hogebuilt and RoadWorks typically feature 304-grade stainless steel construction with mirror polish finish. Budget-friendly options often use chrome-plated steel, which provides good appearance but may require more maintenance in harsh climates. Each product listing specifies the exact material. For maximum corrosion resistance in winter road conditions, we recommend genuine stainless steel options.

Will adding roof accessories affect my fuel economy or create wind noise?

Properly designed roof fairings and deflectors can actually improve aerodynamics and reduce wind noise. However, accessories like light bars, air horns, and antennas mounted above the roofline may create additional drag, potentially reducing fuel economy by 1-3% at highway speeds. Wind noise is most common with improperly installed or loose accessories. Using OEM-style mounting hardware and following torque specifications helps minimize noise issues.

What finish options are available, and how do they hold up over time?

Common finish options include mirror-polished stainless, brushed stainless, chrome, and powder-coated black. Mirror-polished stainless maintains its appearance best but shows fingerprints and requires regular polishing. Chrome finishes look excellent initially but may pit or peel after 2-3 years in harsh conditions. Powder-coated options resist corrosion well but may fade with UV exposure. Most customers in northern climates prefer stainless steel for longevity, while southern drivers often choose chrome for the initial shine.
