Saddle boxes are shaped to sit over the wheel wells on either side of the truck bed, putting storage in space that a standard rectangular box can't reach. Because they straddle the wheel arch rather than sitting beside it, saddle boxes add organized, lockable storage without reducing the usable floor length of the bed. We carry saddle boxes from trusted brands in configurations for single-side and both-side installation on most full-size and mid-size trucks.
Storage That Uses the Space Around the Wheel Well
The wheel wells in a truck bed are one of the biggest sources of wasted space. Saddle boxes are specifically shaped to fit over and around the wheel arch, turning that dead space into secure, organized storage. Because the box sits over the wheel well rather than on the flat floor of the bed, it doesn't reduce the usable cargo length — you can still use the full front and rear of the bed for materials and equipment.
Access is through a top-opening lid on each side, giving you reach from outside the bed without having to climb in. The lid holds open on a gas spring or stay arm so both hands stay free while you're loading and unloading.
Single and Paired Configurations
Saddle boxes are available as single units for one wheel well or as matched pairs for both sides of the bed. A single box on the driver's side gives you quick curbside tool access. A matched pair doubles your storage without using any additional cargo floor space.
Better Built and WeatherGuard build their saddle boxes from heavy-duty aluminum and steel with weather-seal compression latches and corrosion-resistant finishes built for long-term outdoor use on work trucks.

Frequently Asked Questions
A saddle box is shaped to sit over the wheel well on one or both sides of the truck bed, using the space around the wheel arch for storage without taking up usable cargo floor area.
Not significantly. Because saddle boxes sit over the wheel well, they don't occupy usable floor space in the bed. They put storage in space that was already unusable.
Yes. Saddle boxes are available as individual units or matched pairs for installation on both wheel wells.
A crossover box spans the full width of the bed at the cab end. A saddle box straddles the wheel well on one or both sides, leaving the front of the bed and the center open.
