Get secure, out-of-the-way storage with our Inframe Toolboxes—available in two sizes to match your rig's setup. Both models mount between the frame rails and can be installed in under 30 minutes with the included no-drill mounting kit. The 22" wide model measures 9" high by 24" deep, giving you compact storage for DEF, tire chains, tools, or washer fluid—without crowding your truck deck. The 23" wide version adds a center channel that straddles your driveshaft, giving you 13" of internal height and 18" of depth for more gear storage in a space most trucks waste. Both are built from strong, lightweight ⅛" thick aluminum with a checkerplate lid for grip when stepping, and sealed up tight with a stainless steel draw latch for added security. If you're looking to max out the storage space on your rig, these boxes are a smart, out-of-the-way choice.
