This Yukon Zip Locker fits Dana 30 axles with 27 spline axle shafts.

This locker includes two new carrier bearings and shims. Some applications require additional shims.

This unit is drilled for 7/16" ring gear bolts. Ring gears with 3/8" bolts require sleeves.

This differential will only work with 3.73 and numerically higher gears. Do not use thick gears.

Yukon Zip Lockers are the latest in on-demand, air-operated lockers that allow you to switch from an open differential to a full lockup spool when additional traction is needed. This modern locker design gives you the ultimate balance of vehicle driving control and long lasting reliability. They are just as well suited for street use as they are under hardcore off-road abuse thanks to their 4320 Chrome Moly internals for added strength and a near perfect non-failure rate over the past 4 years. Each unit is assembled in the USA and many of the internal parts are manufactured in the US for superior quality control and durability.

Plus, as if all of these great features aren't enough, or if the low relative price compared to our ARB Air Lockers is a concern to you, all Zip Lockers are backed by the best warranty in the business. If, in the rare instance that the unit you purchase were to ever fail within the first 2 years of use, Yukon will not only cover the cost of replacing the locker, they will also reimburse you for collaterally damaged parts and associated labor, up to $2,000!

Yukon Zip Lockers require a pressurized air source to engage and disengage their locking mechanism and Filthy Motorsports has you covered with five ARB compressor options ranging from the small and compact ARB CKSA12 all the way up to the powerful and portable high capacity twin compressor ARB CKMPT12 kit.
