Peterbilt 587 Frame & Chassis

Frequently Asked Questions About Peterbilt 587 Frame & Chassis

What years and models are compatible with Peterbilt 587 frame and chassis parts?

Peterbilt 587 frame and chassis components are specifically designed for model years 2011-2017. While many parts share compatibility across these years, critical components like frame rails, crossmembers, and suspension brackets may have variations between early models (2011-2013) and later models (2014-2017). Always verify your specific OEM and build date when ordering structural components, as Peterbilt made mid-year changes that can affect fitment.

What are the most common frame and chassis issues I should watch for on my 587?

The most frequently reported concerns include frame rail corrosion near the fifth wheel area, crossmember fatigue cracks at mounting points, and suspension bracket wear. Regular inspections should focus on these areas, particularly if your truck operates in harsh weather conditions or carries heavy loads. Frame coating degradation typically starts showing after 5-7 years, making protective treatments essential for longevity.

Can I install frame and chassis components myself, or do I need special tools?

While basic components like mud flaps and light brackets can be installed with standard tools, major frame work requires specialized equipment. Frame rail repairs, crossmember replacements, and suspension modifications need proper alignment tools, torque specifications, and often welding capabilities. Most chassis work also requires the truck to be properly supported on heavy-duty stands. We recommend professional installation for any structural components to maintain safety and warranty compliance.

What material grades and finishes are available for 587 chassis components?

OEM-spec frame components are typically made from high-strength steel with yield ratings between 50,000-110,000 PSI, depending on the application. Finishes include e-coat primer, powder coating, and hot-dip galvanizing for maximum corrosion resistance. Aftermarket options may offer aluminum alternatives for weight savings on non-structural parts. Always match or exceed OEM material specifications when replacing frame components to maintain structural integrity.

How do I determine the correct frame rail length and wheelbase specifications?

Your Peterbilt 587's frame specifications are found on the vehicle identification plate located on the driver's side door jamb. Look for the wheelbase (WB) measurement and frame rail length codes. Common configurations range from 180" to 244" wheelbase. When ordering frame extensions or modifications, you'll need both the existing wheelbase and the desired final measurement. Frame rail height for the 587 is typically 10.25" or 11.25", which must match exactly for proper component fitment.
