Will these frame steps fit my specific year Peterbilt 379?
Most frame steps are designed to fit Peterbilt 379 models from 1987-2007, but fitment can vary based on your truck's configuration. Extended hood models (127" and 131" BBC) may require different mounting brackets than standard hood models. Always verify your truck's wheelbase and check if you have aftermarket modifications like lowered suspensions or custom exhaust systems that could affect clearance. When in doubt, measure the mounting area and compare it to the product specifications listed on each item page.
What's the difference between aluminum and stainless steel frame steps?
Aluminum steps are lighter (typically 40-60% less weight than steel), won't rust, and are easier to polish but can show scratches more easily and may bend under extreme weight. Stainless steel steps are more durable, support heavier loads (usually rated for 500+ lbs), and maintain their appearance longer but require more maintenance to prevent water spots and are significantly heavier. For daily drivers, aluminum works great. For heavy-duty applications or if you frequently carry heavy items, stainless steel is the better investment.
Can I install these frame steps myself, or do I need professional help?
Most frame steps can be installed with basic tools in 2-4 hours. You'll typically need a drill with metal bits, wrenches, and possibly a rivet gun. The main challenges are ensuring proper alignment and drilling into the frame rails correctly. Some drivers report difficulty with certain cab configurations where fuel tanks or exhaust components limit access. If you're comfortable with basic mechanical work and have a helper to hold steps in position while marking holes, DIY installation is achievable. Professional installation typically runs $150-300 if you prefer that route.
How do I choose between battery box steps, cab access steps, and full-length running boards?
Battery box steps mount directly to your battery box and work best for trucks with standard fuel tank configurations. Cab access steps are individual units that mount to the frame and offer more flexibility in positioning but less stepping surface. Full-length running boards provide maximum stepping area and a unified look but are heavier and more expensive. Consider your typical use: battery box steps are great for quick cab access, individual steps work well with custom setups, and full-length boards are ideal if passengers frequently enter/exit or you need tool storage underneath.
What maintenance do these steps require to prevent corrosion and maintain appearance?
Aluminum steps need regular washing with soap and water, plus aluminum polish every 2-3 months to maintain shine. Avoid harsh chemicals that can cause pitting. Stainless steel requires more frequent cleaning to prevent water spots and should be polished with stainless-specific products monthly. Check mounting hardware every 6 months for looseness caused by vibration. In winter salt states, rinse steps weekly to prevent corrosion at mounting points. Most customers report that 15-20 minutes of maintenance per month keeps steps looking showroom fresh for years.
