Peterbilt 359 Parts

Frequently Asked Questions About Peterbilt 359 Parts

What years and models are compatible with your Peterbilt 359 parts?

Our Peterbilt 359 parts are designed to fit all 359 models manufactured from 1967 to 1987. Most exterior parts like bumpers, grills, and fenders are interchangeable across all production years. However, some interior components and electrical parts may have variations between pre-1980 and post-1980 models. When ordering engine-specific or cab interior parts, please have your OEM number ready or contact our team to verify exact fitment for your specific truck.

Are your bumpers made from chrome-plated steel or stainless steel, and which is better?

We carry both chrome-plated steel and polished stainless steel bumpers. Chrome-plated bumpers offer a classic mirror finish at a lower price point but require regular maintenance to prevent rust and pitting. Stainless steel bumpers cost more upfront but resist corrosion without special care and maintain their appearance longer, especially in harsh weather conditions. For trucks exposed to road salt or coastal environments, we recommend stainless steel for its superior durability.

What tools and modifications are needed to install aftermarket parts on my 359?

Most bolt-on parts like bumpers, mirrors, and air cleaners require standard hand tools and can be installed in 1-3 hours. Bumper installation typically needs a socket set, torque wrench, and possibly a helper for alignment. Some aftermarket upgrades may require minor drilling or bracket modifications. Electrical components like LED conversions often need wire splicing or adapter harnesses. We include detailed instructions with each part and offer phone support if you encounter installation challenges.

How do I choose between different hood styles and what affects the fit?

The two main hood styles for Peterbilt 359s are the standard hood and the extended hood (127" BBC). Your choice depends on your engine size and desired appearance. Measure from the center of your front axle to the back of your cab to determine your BBC (Bumper to Back of Cab) measurement. Standard hoods work with most engine configurations, while extended hoods provide extra clearance for larger engines like the CAT 3406B or Cummins N14.

What is the typical lifespan of aftermarket parts compared to OEM, and what warranty coverage is available?

Quality aftermarket parts from reputable manufacturers typically match or exceed OEM lifespan when properly installed and maintained. Chrome bumpers usually last 5-7 years with regular care, while stainless steel can last 15-20 years or more. Most parts carry a 1-year warranty against defects, with some stainless steel components covered for up to 3 years. Wear items like air filters and brake components have shorter warranties based on expected service life. Always check individual product pages for specific warranty terms.
