Shop Aftermarket Mack RD Truck Parts

Working, old-school big rigs like the Mack RD series endure many years of wear and tear on jobs sites. Over time, Mack RD hardware and components experience high heat and pressure, turning mild components replacements into system-wide repairs. We stock the model-specific mechanical parts to keep your hard-working truck performing day after day:

Cosmetic Aftermarket Upgrades for Mack RD Trucks

Road debris can chip away at the headlights, fenders, mirrors, and even mud flaps over time. That’s why we stock hundreds of exterior Mack RD replacement parts to replace damaged parts. Lastly, you can find decorative custom upgrades to spruce-up the look of your rig, from interior custom dashboards to stainless steel step boxes for easy cab exit and entry.

Frequently Asked Questions About Mack RD Truck Parts

What years and models of Mack RD trucks do your parts fit?

Our Mack RD parts are designed to fit RD600, RD688, and RD690 models manufactured from 1979 through 2004. However, compatibility can vary based on specific configurations and factory options. We recommend checking your OEM or contacting our team with your truck's model year and any special equipment codes to ensure proper fitment before ordering.

Are your Mack RD bumpers made from chrome-plated steel or stainless steel?

We offer both options depending on your needs and budget. Our chrome-plated steel bumpers feature a triple-chrome plating process over heavy-gauge steel for durability and shine. Our stainless steel options are typically 304-grade stainless with a mirror polish finish. Chrome bumpers are more affordable but require regular maintenance, while stainless steel resists corrosion better in harsh conditions but comes at a higher price point.

Do I need special tools or professional installation for Mack RD bumpers?

Most Mack RD bumper installations can be completed with standard shop tools including socket sets, wrenches, and a drill for any additional mounting holes. The bumpers typically weigh between 80-150 pounds, so having a helper or hoist is strongly recommended. Installation usually takes 2-4 hours. Some aftermarket bumpers may require minor modifications to mounting brackets or drilling new holes. Professional installation is recommended if you're not comfortable with heavy lifting or drilling.

What's the difference between OEM-style and aftermarket Mack RD parts?

OEM-style parts are manufactured to match original factory specifications for direct bolt-on replacement. Aftermarket parts may offer enhanced features like additional gauge holes, different styling, or heavier construction but might require modifications during installation. OEM-style parts typically maintain factory warranty compliance, while aftermarket options often provide better value and customization options. Both meet DOT standards when applicable.

How do I maintain chrome parts on my Mack RD to prevent rust and pitting?

Chrome parts require regular maintenance to maintain their appearance, especially in regions using road salt. Wash chrome surfaces weekly with mild soap and water, then dry thoroughly. Apply a quality chrome polish monthly and use a chrome sealant every 3-4 months for added protection. Avoid abrasive cleaners or steel wool which can scratch the chrome. For winter storage or harsh conditions, consider applying a thin coat of WD-40 or similar protectant, then remove before regular use.
