Frequently Asked Questions About International 9300/9370 Sleeper Side Accessories

Will these sleeper side accessories fit my specific International 9300 or 9370 model year?

Our sleeper side accessories are designed to fit International 9300 and 9370 models from 1987-2007. However, there are variations between early and late model years. Pre-2000 models may require different mounting brackets than 2000-2007 models. We recommend checking your VIN or contacting our support team with your specific year and sleeper configuration to ensure proper fitment before ordering.

What materials are these accessories made from, and how long will they last?

Most of our International 9300/9370 sleeper side accessories are manufactured from either 304 stainless steel or heavy-duty ABS plastic with chrome plating. Stainless steel options typically last 10-15 years with proper maintenance, while chrome-plated ABS pieces generally last 5-7 years depending on road conditions and care. All metal accessories include rust-resistant hardware and mounting brackets rated for highway use.

Do I need special tools or professional installation for these accessories?

Basic installation typically requires standard hand tools including drill bits (usually 3/8" and 1/2"), socket wrenches, and a cordless drill. Most accessories can be installed in 1-3 hours by someone with moderate mechanical experience. Some items may require removal of interior sleeper panels for proper mounting access. We provide detailed installation instructions with each product, though professional installation is recommended for electrical accessories or extensive modifications.

What styles and finishes are available for sleeper side panels and trim?

We offer three main finish options: mirror-polished stainless steel, standard chrome-plated, and powder-coated black. Style options include smooth panels, quilted/diamond plate patterns, and louvered designs. Extended cab sleepers (70" and 86") have different panel sizes than standard sleepers, so measurements are critical. Custom etching and LED backlighting are available on select stainless steel models for an additional charge.

How do these accessories affect aerodynamics and fuel efficiency?

Properly installed sleeper side fairings and panels can actually improve aerodynamics by smoothing airflow around the cab-to-sleeper transition. Most drivers report minimal to no impact on fuel economy, with some seeing slight improvements of 0.1-0.3 MPG on highway routes. Avoid accessories that protrude more than 2 inches from the sleeper surface, as these can create drag. Wind deflectors and cab extenders are specifically designed to enhance aerodynamic performance when correctly positioned.
