Frequently Asked Questions About Peterbilt 357/378 Frame Steps & Acc.

Will these frame steps fit my specific Peterbilt 357 or 378 model year?

Most frame steps for Peterbilt 357/378 models are designed to fit trucks manufactured from 1987 through 2007. However, minor variations exist between early models (1987-1999) and later models (2000-2007) due to frame rail spacing changes. Always verify your truck's exact year and measure the mounting points before ordering. If you're unsure, contact us with your VIN and we'll help confirm compatibility.

What's the difference between aluminum and stainless steel frame steps?

Aluminum steps are lightweight (typically 8-12 lbs per step), resist corrosion well, and cost less upfront. However, they may show wear faster under heavy use. Stainless steel steps are heavier (15-20 lbs per step) but offer superior durability and maintain their appearance longer, especially in harsh weather conditions. For trucks in salt-heavy regions or those seeing daily heavy use, stainless steel typically provides better long-term value despite the higher initial cost.

Do I need special tools or professional installation for frame steps?

Basic frame step installation typically requires standard tools: drill with metal bits, wrenches, and measuring tape. Most steps mount using existing frame holes or require drilling 2-4 new holes per step. Installation usually takes 1-2 hours per side for someone with basic mechanical skills. However, if your frame has modifications or you're installing steps with integrated lighting, professional installation may be worthwhile to ensure proper alignment and electrical connections.

What finish options are available and which holds up best?

Common finishes include polished aluminum, brushed stainless, powder-coated steel, and chrome-plated options. Polished aluminum requires regular maintenance to prevent oxidation. Brushed stainless offers the best combination of durability and low maintenance. Powder-coated steps resist chips and corrosion well but may fade over time. Chrome looks great initially but can peel or rust if the coating is compromised. For minimal maintenance, brushed stainless or quality powder coating are your best bets.

How do I choose between bolt-on and weld-on frame steps?

Bolt-on steps are the most popular choice, allowing easy installation and removal for maintenance or replacement. They typically use grade 8 bolts and can be installed in under an hour per side. Weld-on steps provide a cleaner look and maximum strength but require professional welding and are permanent. Choose bolt-on if you value flexibility and DIY installation. Choose weld-on only if you have access to qualified welding services and want the absolute strongest mount possible.
