2021-2025+

The Peterbilt 535 and Peterbilt 536 are part of Peterbilt’s new-generation medium-duty lineup, launched in 2021. They are built on the same redesigned platform and feature the 2.1-meter wide cab, similar to Peterbilt’s larger highway trucks and the Kenworth T180/T280.

  • Peterbilt 535: Designed for non-CDL Class 5 applications (GVWR under 26,000 lbs).
  • Peterbilt 536: Built for CDL-required Class 6 jobs (GVWR up to 33,000 lbs).

Both trucks offer a modern, aerodynamic design with improved visibility, ergonomics, and driver comfort—ideal for fleet operations and vocational work that values uptime, comfort, and safety.

Model Typical Applications
535 Pickup & delivery, light-duty flatbed, utility, small box or reefer
536 Regional delivery, medium-duty dump, tow & rollback, municipal utility

Cab Type: 2.1-Meter Wide Cab

  • Same cab shell used in Peterbilt 567 and Kenworth T280.
  • Offers more interior space, wider seats, and highway-style dash ergonomics.
  • Available in vocational trim or premium interior, depending on spec.

Aftermarket Seat Compatibility

Because the 535 and 536 use the 2.1m wide cab, they do require a seat adaptor plate for most aftermarket seating. The bolt pattern differs from the traditional 4.68" x 12" vocational standard and aligns more closely with the 6" x 12" wide-body layout used in other 2.1m-cab Peterbilt and Kenworth models.

Popular aftermarket options:

  • National Admiral or Commodore – requires 2.1m adaptor plate for HP suspension
  • Knoedler Air Chief – requires 2.1m adaptor plate
  • Gramag Smart MR – available with specific adaptor for 2.1m cabs

Installation Notes

  • Confirm 2.1m cab by VIN, door label, or spec sheet.
  • Use seat-specific adaptors to match bolt pattern and elevation.
  • For electric/heated seats, check for power supply availability in-cab.
  • Allow room for seat travel; some wide suspension bases may restrict movement against the door or console.
