By Nick Marchenko, PhD

When embarking on an adventurous road trip or a weekend getaway, especially with loved ones, there's often a need for extra cargo space. Even with the spaciousness of your RAM 2500, sometimes there's a need for extra storage for gear such as skis, surfboards, or kayaks.

That's where the RAM 2500 roof rack comes into play. It offers you the opportunity to securely mount additional items atop your truck.

If you've recently acquired a roof rack, you might be pondering: How do I install it on my RAM 2500?
No need to fret; this guide is here to walk you through the roof rack installation process.

Which Roof Racks Are Suitable for the RAM 2500?

Roof racks not only amplify the storage capacity of your RAM 2500 but also provide room for various equipment ranging from sports gear to outdoor essentials.

The market offers several roof rack variations tailored to specific needs:

Crossbar Roof Racks are prevalent. They comprise horizontal bars spanning the width of the RAM 2500's roof, serving as a foundation for attaching accessories like cargo carriers, bike or ski racks, and kayak mounts.

Crossbar roof racks can be affixed to RAM 2500 models with raised factory-installed side rails or even those with a clean roof using special mounting mechanisms.

Raised Side Rail Roof Racks. This roof rack type is characterized by rails that span from the truck's front to its rear.

They offer mounting points for crossbars and other attachments, blending aesthetics with utility for your RAM 2500.

Flush-Mount Side Rail Roof Racks also come with factory-installed rails, but they sit flush with the RAM 2500’s roof for a more aerodynamic silhouette. They're versatile and enhance the truck's overall appearance.

Roof Baskets and Cargo Trays provide an open structure, ideal for carrying large items like camping gear or oversized bags on your RAM 2500.

Cargo Boxes are enclosed storage solutions, easily mounted on the RAM 2500's crossbars. These cargo boxes protect your belongings from the elements while offering ample storage space.

Bike Racks facilitate the secure transport of bicycles atop your RAM 2500. Whether you prefer roof-mounted, fork-mounted, or frame-mounted racks, there's an option to match your needs.

Kayak and Canoe Carriers are designed to securely fasten kayaks or canoes for transportation. They often feature padded cradles and adjustable arms to ensure stability during transit.

Ski and Snowboard Racks provide dedicated clamps mounted to crossbars to securely hold snow gear. Their varied sizes cater to diverse snow equipment needs.

Installation Steps:

1. Review the Manual Carefully

Begin by thoroughly reading the provided installation manual from the roof rack manufacturer. RAM 2500 models may have different specifications, so it's crucial to adhere to the manual tailored for your truck.

2. Set Up the RAM 2500

Park your RAM 2500 on a flat surface. Ensure all the doors and windows are shut. If your truck already comes with roof rails, make sure to follow the manual regarding their removal or adjustment.

3. Mark and Set the Crossbars

Using a measuring tape, determine the precise distance between the front and rear crossbars as outlined in the manual. Lay out the crossbars on the RAM 2500 roof as described in the guide.

4. Secure the Mounting Feet 

For roof racks equipped with mounting feet, fasten them to the crossbars following the provided instructions. Ensure they are snug but avoid over-tightening.

5. Place the Crossbars

Set the crossbars onto the mounting feet and make sure they're evenly positioned on both sides of the RAM 2500 roof.

6. Align and Fasten

Adjust the crossbars according to the specified spacing in the manual. If your roof rack features adjustable feet, ensure they match the curvature of your RAM 2500's roof.

7. Tighten All Fixtures

Secure the crossbars to the mounting feet, being mindful of the torque. Over-tightening can potentially damage the roof or the roof rack components.

8. Confirm Adequate Clearance

Inspect the space between the crossbars and the RAM 2500 roof. There should be enough room for the doors to operate without obstruction.

9. Ensure Stability

Gently shake the crossbars to verify their attachment. Retighten any fixtures that may seem loose.

10. Add Roof Rack Accessories

Now's the time to attach any additional equipment – cargo boxes, bikes, kayaks, and more. Always refer to the manufacturer's guidelines.

11. Perform a Final Inspection

Thoroughly check all connection points, bolts, and screws to ensure everything is secure.

12. Guard Your Roof

To prevent potential scratches or marks, place a soft cloth or towel beneath the roof rack's mounting areas.

A vital reminder: If you encounter challenges during the installation, it might be prudent to seek help from someone experienced with roof rack installations.

Conclusion

When selecting a roof rack for your RAM 2500, factor in the vehicle's structure, the nature and weight of your cargo, and your specific needs. Adhere to the recommended installation procedure or consider professional installation to ensure the safety and longevity of your equipment.
