Enhance Load Bearing & Stability

Aftermarket suspension components are way cheaper than OEM parts. The performance is on par too. Installing new leaf springs or air suspension parts can even improve your Peterbilt's ride quality, handling, and load stability. You can also find frame-mounted accessories to further upgrade your Peterbilt, including Peterbilt 330/335/337 tool/battery boxes, Peterbilt 330/335/337 fuel tanks and Peterbilt 330/335/337 mud flaps!

Frequently Asked Questions About Peterbilt 330/335/337 Frame & Chassis

What years and specific models do these frame and chassis parts fit?

Our frame and chassis components are designed for Peterbilt 330, 335, and 337 models typically ranging from 2005 to present. However, compatibility can vary based on specific configurations and production changes. We recommend checking your OEM or contacting our parts specialists with your truck's year, model, and any special equipment codes to ensure proper fitment before ordering.

Are these aftermarket or OEM parts, and what's the difference in quality?

We carry both genuine OEM Peterbilt parts and high-quality aftermarket alternatives. OEM parts guarantee exact factory specifications and fitment, while our aftermarket options often provide comparable quality at a lower price point. All aftermarket parts we stock meet or exceed DOT standards and typically feature heavy-duty steel construction with corrosion-resistant finishes. Each product listing clearly indicates whether it's OEM or aftermarket.

What tools and expertise are needed for installation?

Most frame and chassis component installations require standard shop tools including impact wrenches, torque wrenches, and basic hand tools. Depending on the specific part, you may need lifting equipment or a truck hoist. While many experienced mechanics can handle these installations, some components like frame rails or suspension brackets require precise alignment and torque specifications. Professional installation is recommended for major structural components.

How do I know if I need to replace frame or chassis components?

Common signs include visible rust or corrosion, cracks in frame rails or crossmembers, bent or damaged brackets, loose or worn mounting points, and unusual vibrations or handling issues. During regular inspections, pay special attention to areas exposed to road salt, moisture, or heavy stress. If you notice any structural damage or excessive wear, replacement is crucial for safety and DOT compliance.

What finish options are available and which holds up best?

Most frame and chassis parts come in either black powder coat, e-coat primer, or bare steel finishes. Powder coating offers the best long-term corrosion resistance and durability, especially in harsh weather conditions. E-coat primer provides good protection and allows for custom painting. Bare steel requires immediate priming and painting after installation. For maximum longevity in salt-belt states, we recommend powder-coated components or applying additional undercoating after installation.
