JCKEL MONKEY GRIP LUNCHBOX LOCKER - DANA 30-27 SPLINE

Before I bought this locker, I struggled to climb parking lot curbs. Putting this locker it made it a king of hammers competitor. Shannon Campbell will not hold a candle against this jeep.

I installed this on my 91 yj front diff. install took a few hrs on a lift i was by no means rushing. Could be done in a driveway just as easy. several youtube videos even a novice could tackle install. For trail riding with 31s this may be the best upgrade OFF ROAD. If you have a one piece axle with out locking hub i would not recommend. This changes driving on road as well. watch the videos and ask questions.

If using this in a jk/jku d30 front you will need either new carrier for 3.73 up gears or when using the oem 3.21 carrier will need new axle thrust washer/shims to get correct spacing.

Installed these in a Dana 30 front on a 98' Cherokee. Instructions were detailed and well written. Installs with basic hand tools. Hit the ORV park the next weekend and went everywhere.

Every thing was perfect they even sent me extra stickers and a sticker from the distributor which will be on my jeep for its next trip out I support national drivetrain 100%.

Super easy to install works like a charm

It works
