Description

The USA Standard Gear Spartan Locker is a robust lunchbox locker engineered to significantly enhance off-road capability for your vehicle's Dana 44HD differential. Featuring a 30 spline count and constructed from high-strength 9310 steel, this locker guarantees reliable, 100% lockup traction in demanding conditions. Its innovative spring and pin design eliminates the need for thrust washers, simplifying installation and ensuring a secure fit within a standard carrier case. This mechanical locker provides consistent power distribution to both wheels, offering a noticeable improvement in grip and stability for tackling tough terrains. The Spartan Locker is designed for 1996-2004 Jeep Grand Cherokee ZJ and WJ models. Installation is straightforward, with an approximate time of 20 minutes and a simple difficulty level.
