EcoBox Integrated Builder Bundle

The Ultimate DIY Reduction Kit for Hardcore Builders

This billet aluminum underdrive box mounts directly between your transmission and a selection of transfer cases, giving you serious low-range gearing for maximum off-road control.

Built for experienced builders, this kit ships as a bare housing—you provide the planetary gearset (compatible with NP241C-style assemblies) and finish the build your way.

Looking to step things up?
Upgrade to the Eco HD Lid—featuring an integrated bearing retainer and delivering 1.5× the load rating of the standard lid. Ideal for high-torque builds or added peace of mind when you're pushing hard on the trail.

Key Features:

Direct Bolt-On Fitment:
Dana 300, Dana 20, and Atlas-II transfer cases
DIY-Ready:
Ships as a bare housing, ready for NP241C-style planetary gearsets
Built to Last:
CNC-machined from billet aluminum for exceptional strength and durability
Compact Design:
Only 5.36" with the Standard Lid, or 6.39" with the Eco HD Lid

Note: Planetary gearset not included. Requires intermediate mechanical knowledge for proper assembly.
