2025 Ram 1500 Side Mount Toolboxes

2025 Ram 1500 Side Mount Toolboxes

Side mount toolboxes sit on top of the bed rails along the sides of the bed, so your tools are easy to reach from outside the truck and the middle of the bed stays open. This page shows the Lo-Side, Hi-Side and side mount boxes from Weather Guard® and TrailFX that are listed to fit the 2025 Ram 1500.

Fitment notes for the 2025 Ram 1500

• Generation: the 2025 Ram 1500 is part of the current Ram 1500 generation (2019 and newer).
• Beds: manufacturer fitment data for this truck covers the 5 ft. 7 in. (5 ft. 7.4 in.) and 6 ft. 4 in. (6 ft. 4.3 in.) beds. A side mount box runs along the rail, so its length has to suit your bed length.
• Length: long boxes, such as the 87 in. Weather Guard® Lo-Side and the 90 in. Weather Guard® 390 Hi-Side, are listed for long (8 ft.) beds only; the shorter 41 in. and 56 in. Lo-Side models take up less of the rail. Each product page lists the exact beds it fits. The current Ram 1500 has no 8 ft. bed, so make sure a box lists your 5 ft. 7 in. or 6 ft. 4 in. bed before you buy.
• Style Side beds: these boxes are made for pickup beds. Always measure your bed rails to confirm fit.

How to choose

• Lo-Side: sits low along the rail for a clean look and a clearer view over the bed.
• Hi-Side and Super Hi-Side: stand taller, open with doors and hold more (for example 11.1 cu. ft. on the Weather Guard® 390 Hi-Side and 15.2 cu. ft. on the 391 Super Hi-Side), a common choice for work trucks.
• Aluminum or steel: aluminum is lighter and won't rust; steel is heavier and very tough.
• One side or both: many work trucks run a box on each side; plan for the bed space and cargo you still need.

2025 Ram 1500 Side Mount Toolbox FAQ

Side mount or crossover for my 2025 Ram 1500?

A crossover box keeps everything in one spot behind the cab. Side mount boxes keep tools reachable from the side of the truck and leave the front of the bed open. Our comparison guide walks through both.

Which length do I need?

Measure the bed rail from the front of the bed to the tailgate and compare it with the box length in each listing. The product pages list the bed lengths the manufacturer lists for each box.

Can I still use a tonneau cover?

Usually not with a standard cover, because side mount boxes sit on the rails the cover needs. Check the box's and cover's notes before you buy.
