Behemoth Drivetrain

Colossus Case for Dana 300 or NP205


Battle tested in the field for more than a decade, the Behemoth Drivetrain Colossus case has proven itself to be one of the best upgrades you can make for your drivetrain.

Behemoth offers both a Dana 300 and NP205 model, with either 26 spline or 32 spline options.  Please choose the correct option for your build from the drop down Options menu.

SKU: Colossus-Case Categories: , ,
This item will be released September 15, 2021.

Made from a solid 6061 aluminum block, the Behemoth Colossus Case is lighter and stronger than a stock Dana 300 housing. Add to that nearly endless clocking, built-in “Twin-Stick” shift mechanism, and the ability to be assembled either right or left hand drop, and you have one answer to all your transfer case questions.

Includes: billet main housing, billet housing cover, installed shift mechanisms, partially installed shift forks (some minor assembly required), front output retainer / cover, and all necessary hardware.
