Frequently Asked Questions About Peterbilt 375/377 Fuel Tank Steps
What material are these fuel tank steps made from, and will they rust or corrode?
Most Peterbilt 375/377 fuel tank steps are manufactured from either polished stainless steel or heavy-duty aluminum. Stainless steel options provide excellent corrosion resistance and maintain their shine with minimal maintenance. Aluminum steps are lighter weight and naturally resist rust, though they may show oxidation over time if not properly maintained. Both materials are designed to withstand road salt, weather exposure, and diesel fuel contact without degrading.
Will these steps fit my specific Peterbilt 375 or 377 model year?
Fuel tank steps for Peterbilt 375 and 377 models are generally compatible across model years from 1987 to 2007, as the fuel tank mounting configurations remained consistent. However, you should verify your truck's specific tank size (typically 100, 120, or 150 gallons) and mounting bracket style before ordering. Custom exhaust configurations or aftermarket modifications may affect fitment. When in doubt, measure your existing step mounting points or contact us with your VIN for verification.
How difficult is the installation process, and what tools do I need?
Installation typically takes 30-60 minutes per side and requires basic hand tools including a socket set, wrenches, and possibly a drill for new mounting holes. Most steps use existing mounting points on your fuel tank brackets, making installation straightforward. The main challenges customers report include accessing tight spaces between the tank and frame rail, and ensuring proper alignment before final tightening. Having a second person to hold the step in position while securing bolts is highly recommended.
What's the difference between flat, diamond plate, and grip strut step styles?
Flat steps offer a clean, classic appearance and are easiest to keep clean but may become slippery when wet. Diamond plate steps feature raised patterns that provide better traction in all weather conditions and hide minor scratches well. Grip strut steps have the most aggressive tread pattern with punched holes or serrations, offering maximum slip resistance but can trap more dirt and debris. Your choice should balance safety needs with maintenance preferences and the overall look you want for your truck.
How much weight can these steps support, and will they bend under heavy use?
Quality fuel tank steps for Peterbilt 375/377 trucks are engineered to support 300-500 pounds when properly installed, exceeding DOT requirements. The mounting brackets and step platforms use reinforced designs with gusseted corners to prevent bending. However, repeated impacts from dropped tools or excessive side loading can cause deformation over time. For maximum durability, choose steps with welded (not bolted) construction and thicker gauge material, especially if multiple drivers use your truck or you frequently carry heavy items while climbing.
