  1. Budget locker bang for your buck If you decide to go this route it’s a budget locker it works well install is about 3-4 hrs taking your time .Driving with it takes some getting use to but others may have different affectsIt will magnify any loose steering you have also check all ujoints on axle shaftsAnd make sure to take up to freeway speeds drive to insure you did correctlyAlso make sure to change your diff fluid after couple hundred miles you’ll see so brass shaving in oil so don’t freak out…

  2. Locked and ready USA standard gear’s Spartan locker is the first locker I’ve ever driven and this was the first time I ever took an axle apart. Took me a couple hours to get everything disassembled but what a simple install. No more spider gears crawling through my diff, now I can show off on the trail and stall more, lockers take some getting used to but they’re an incredible off-road upgrade especially for the price. I’m driving a 95 Jeep Wrangler lifted 4″ with 33s converted to a tj style front axle…

  3. I am unstoppable. Until I break an axle shaft. Bought a front for my D30 and rear for my 8.25 and am very satisfied with them. On road is not bad and I don’t mind the tick in reverse and gunshot when the front unlocks sometimes, I wheel my jeep, I didn’t buy these for other’s opinions. On the rocks they are flawless. I’m sure I’ll break axle shafts soon but for now, I am unstoppable. These are very easy to install and all parts and instructions were provided. Spartan lockers are great.
