Frequently Asked Questions About Peterbilt 330/335/337 Front Bumpers

Will these bumpers fit my specific Peterbilt model year?

Our Peterbilt 330/335/337 front bumpers are designed to fit models from 2005 to current production years. However, there are slight variations between model years. Bumpers for 2005-2007 models have different mounting hole patterns than 2008 and newer models. When ordering, please have your VIN ready or know your exact model year to ensure proper fitment. If you're unsure, our customer service team can verify compatibility before you order.

What's the difference between chrome, stainless steel, and painted bumper options?

Chrome bumpers offer a mirror-like finish but require regular polishing to maintain their appearance and can show pitting over time in harsh climates. Stainless steel bumpers provide excellent corrosion resistance with less maintenance, though they have a brushed finish rather than mirror shine. Painted bumpers come primer-ready or pre-painted in common Peterbilt colors and are ideal for fleets wanting a uniform look. Chrome typically costs 20-30% more than painted options, while stainless falls in between.

Can I install these bumpers myself, or do I need professional installation?

Installation typically takes 2-4 hours and requires basic mechanical skills. You'll need standard tools including socket wrenches, a torque wrench, and potentially a helper for lifting. The bumper weighs 45-65 pounds depending on style. Most customers can complete the installation themselves by following the included instructions. However, if you're adding fog lights or need to relocate sensors, professional installation may be recommended to ensure proper wiring and calibration.

Are mounting brackets and hardware included with the bumper?

Most replacement bumpers come with new mounting brackets and grade 8 bolts. However, some economy models may require reusing your existing brackets. Each product listing specifies what's included. If you're converting from a plastic to steel bumper, you may need additional mounting hardware sold separately. Fog light brackets, license plate brackets, and tow hook provisions are typically built into the bumper but the actual accessories are sold separately.

How thick is the steel, and will these bumpers hold up to minor impacts?

Our standard bumpers are made from 14-gauge steel (approximately 0.075 inches thick), while heavy-duty options use 12-gauge steel (0.105 inches). These are significantly more durable than factory plastic bumpers and can withstand minor parking lot bumps and road debris impacts. However, they're not designed as collision protection devices. For severe-duty applications like construction sites or off-road use, we recommend our reinforced models with additional bracing.
