Locker and Limited-Slip Buyer’s Guide
What you need to know before you splurge
A guide to the world of lockers and limited slips for your Jeep
You press the gas pedal, only to see one of your wheels hanging motionless while the
other on the same axle spins. Is the axle broken? Hopefully not. Unless you heard some loud metallic snapping noises, you’re more likely just suffering from a case of open differentials—standard equipment on many factory 4x4s. It’s not just embarrassing—it’s non-productive.
Open differentials are helpful on pavement. They allow your vehicle’s inner and outer wheels to easily spin at different speeds when cornering, instead of fighting with each other and creating excessive tire and drivetrain wear and tear. Take them off-road, however, and they can spell disaster when one wheel finds its way into the air or deep into a mud puddle.
How can you solve this dreadful differential dilemma? Lockers and limited-slip devices from the aftermarket come to the rescue, and thankfully there is a wide selection of traction aids available for your Jeep. Check out the options below to find your perfect traction solution, contact the manufacturers you are interested in for more details, and get all those wheels turning.
