Lock and Unlock your Differential with the Touch of a Button
Your 1985-2010 Super Duty can go just about anywhere when it's equipped with a limited slip differential. The only problem is a fully-locked setup wreaks havoc on your drivability when you aren't in need of the traction control. That's where Yukon's Air-Locking Zip Locker Differential comes in. If you want the peace of mind to take on any off-road trail combined with the smooth turns of an open differential, the Zip Locker is your solution. With the touch of a button, Yukon's Air-Locking Zip Locker allows you to fully lock and unlock your differential for easy recovery when you need it and OE drivability when you're cruising.
Heavy-Duty Air-Operated Design
Yukon designed the Zip Locker Air-Locking Differential to handle the most extreme terrain without issue and maintain OE handling and comfort, making this the perfect upgrade for the weekend off-road rig that doubles as a daily driver. The locker is air-charged and can be operated with your choice of compressor or on-board air system. If airflow is interrupted for any reason, this competition-grade air locker defaults to the lock setting. The assembly is constructed from 100% forged 8620 steel and 4320 chromoly internals for unmatched strength and dependability. This US-made locker kit comes complete with air lines, fittings, seal housing, shims (if needed), switch, front & rear covers, zip ties and installation instructions.
Fitment: 2010 and older 10.5 & 10.25" axles with 35 spline full floating axle shafts
