Frequently Asked Questions About Peterbilt 330/335/337 Sleeper & Related

What years and specific models do these bumpers fit?

Our Peterbilt 330, 335, and 337 bumpers are designed to fit models from 2005 through 2015. The 330 and 335 share the same bumper mounting configuration, while the 337 may require slight modifications depending on your specific chassis configuration. Always verify your truck's OEM and model year before ordering, as Peterbilt made minor mounting changes in 2011 that affect bracket compatibility.

Are these bumpers made from chrome-plated steel or stainless steel?

We offer both options. Our chrome-plated steel bumpers feature a triple-chrome plating process over 16-gauge steel, providing excellent shine at a lower price point. Our 304 stainless steel bumpers are 14-gauge and offer superior corrosion resistance without the maintenance requirements of chrome. The stainless options can be polished to a mirror finish.

What tools and hardware are needed for installation?

Installation typically requires basic hand tools including a socket set (9/16" and 5/8" most common), torque wrench, and drill with metal bits for any custom mounting. Most bumpers do not come with mounting bolts, and you may need to reuse some OEM brackets. Professional installation takes 2-3 hours, while DIY installations average 4-5 hours. Some models require trimming of the lower air dam or relocation of fog lights.

Will aftermarket bumpers affect my warranty or DOT compliance?

Properly installed aftermarket bumpers that meet FMVSS standards will not void your vehicle warranty. All our bumpers are DOT compliant and include proper mounting points for required lighting. However, some states have specific requirements for bumper height and projection beyond the frame rails. Check your state regulations, especially if you operate commercially across multiple states.

How do I match the bumper finish to my existing chrome accessories?

Chrome finishes can vary between manufacturers. Our standard chrome bumpers use a bright nickel process that matches most OEM Peterbilt chrome.
