A beefier differential means less down time and more play time, leading the pack instead of holding up the line. Currie Enterprises has a pretty expansive YouTube channel, aptly named “Currie TV”. On there, Currie has clips of interviews, rock crawl events, short-course racing action, as well as installation videos.

One of the videos that is garnering a fair amount of views isn’t strictly for entertainment. A gentleman named Jeff walks you through a 16-minute video seen above of the full process from start to finish of the build and install of a Currie F9 rearend.

Installing one into a 1971 Ford Bronco classic, the Currie F9 housing will get put to some good use. Being built to the hilt from the get-go, the F9 is destined to see its share of abuse on the trail and highway. Loaded with 4.56 gears and a Detroit Locker, the beef just explodes from there. It’s built with 35-spline axles designed to step up to the massive 1.775-inch inside diameter of a set of Military Spec Set 80 bearings, housed in a 3-inch tube that has a specifically milled flat spot to key into the bulk head of the housing center for extra strength.

Currie F9 axles feature many benefits over the competition: The tubes are welded inside at the bulk head as well as outside to housing center, pre-bends built in to accommodate for welding stresses that would otherwise take the differential out of spec and even “smaller” touches such as a magnet on the inside to collect metal fragments and the gear wear and lock washers on the inside of the third member studs to keep them located.

Currie has put an incredible amount of time into the development and design of the F9 fabricated differential housing and knows how to make a winning set up. Countless off-road rigs of all types are using its rearends with great success. Now sit back and let Jeff walk you through the full process from start to finish.
