Peterbilt 330/335/337 Parts

Frequently Asked Questions About Peterbilt 330/335/337 Parts

What years and specific models are compatible with these parts?

Our Peterbilt 330/335/337 parts are designed to fit models from 2005 through 2024. The 330 and 335 share identical bumper mounting points and dimensions, while the 337 may require slight modifications for certain aftermarket bumpers due to its extended frame rails. Always verify your truck's exact year and model number against our fitment charts, as Peterbilt made minor changes to mounting brackets in 2011 and again in 2018.

Are these bumpers made from steel or aluminum, and how thick is the material?

We offer both steel and aluminum options. Our steel bumpers are typically 12-gauge (0.105 inch) or 10-gauge (0.135 inch) thickness, providing excellent durability for work truck applications. Aluminum bumpers are usually 3/16 inch thick and weigh approximately 40% less than steel equivalents. Steel bumpers come with a powder-coated finish, while aluminum options are available in polished, brushed, or powder-coated finishes.

What mounting hardware is included, and will I need any special tools for installation?

You'll need basic hand tools including 3/4 inch and 7/8 inch sockets, plus a torque wrench to achieve the recommended 120-140 ft-lbs on frame mount bolts. Some installations may require drilling additional holes for accessories like fog lights or tow hooks. Installation typically takes 2-3 hours with basic mechanical experience.

Will aftermarket bumpers affect my truck's approach angle or ground clearance?

Most replacement bumpers maintain the factory approach angle of 23-25 degrees. Heavy-duty work truck bumpers may extend 2-4 inches forward from stock, slightly reducing approach angle but providing better protection. Low-profile sport bumpers can actually improve ground clearance by 1-2 inches. Each product listing includes specific measurements for projection and ground clearance changes compared to OEM specifications.

Do these bumpers accommodate factory fog lights and sensors?

Yes, most of our bumpers include pre-cut openings for factory fog lights found on 2011 and newer models. For trucks with parking sensors (2016+), select bumpers are available with sensor-compatible designs. If your current bumper has fog lights or sensors, look for products marked as "fog light ready" or "sensor compatible" in the description. Wiring harnesses and mounting brackets from your original bumper can typically be transferred to the new unit.
