The Peterbilt 325 is a Class 5 medium-duty truck designed for non-CDL applications. It offers the premium styling and build quality Peterbilt is known for, in a smaller, more maneuverable package ideal for a range of vocational and urban delivery uses.

The 325 is widely used for:

• Local and regional delivery
• Light-duty utility or service applications
• Refrigerated transport
• Towing or rollback configurations
• Landscape and construction supply

Its low GVWR rating (typically under 26,000 lbs) allows for operation without a commercial driver’s license in most states, making it popular for fleets that need flexibility and ease of driver hiring.

Cab Type:

The Peterbilt 325 uses the 1.9-meter cab, the same narrow cab platform shared with the Peterbilt 330 and 337. This cab is designed for vocational durability and simplicity, but with optional comfort features.

Aftermarket Seat Compatibility:

Because the 325 uses the 1.9-meter cab, it typically has a narrow seat mounting base, with a standard bolt pattern close to 4.68" x 12". When installing an aftermarket air-ride seat, the following applies:

• Aftermarket seats bolt in directly (especially vocational models from National or Bostrom)

• Legroom and clearance are important—compact seats or low-profile suspensions are often preferred

Always verify the bolt pattern and height clearance in your cab before purchase. Installations may require air line rerouting or additional spacers, especially in trucks with minimal floor-to-roof height or center consoles.
