Lock-Right Locker

Article written by Moab Man

Date Added: 04/28/2006

Anyone that has really wheeled their vehicle quickly learns about open differentials.

For those that don't know, if you have one tire on the pavement and the other on ice, the tire on ice will get all the power and spin like mad. You are thinking if that tire on the pavement would only turn you would be moving right along. This is where a locker comes in. The locker "locks" the two axles allowing each tire to turn independently of the other tires in situations such as the ice scenario.
This modification is for the mechanically inclined. You need not be a master mechanic but comfortable with understanding mechanical things.
The Powertrax Lock-Right comes with an excellent install manual that covers a few different applications. Because it covers a few applications, take your time, read the book through once, and then read it again as you do the install.
At times the install will be frustrating, you will look at the instructions cursing that there is no way that goes in there. The fit and finish of the Powertrax Lock-Right is very tight. Because of this, there will be times when things just don't want to go together. Keep working at it, when it is lined up just right parts will go together.

Final Thoughts

The Powertrax Lock-Right has been in "T"ank "J"ammer for nine months. Daily driving is accompanied by the ratcheting sound of the locker around corners and occasional tire chirp. Additionally, the Powertrax Lock-Right has been thoroughly tested through Moab Easter Jeep Safari 2002 and one broken axle at Little Moab, Utah.

The increased traction and climbing ability of the locker is immediately noticeable. Climbing steps, rocks, and steep angles that once were challenging are simple now. Down side to this, you start looking for harder things to do. This leads me to the point of breaking axles. The open differential acts as a pressure relief valve when the torque of one axle becomes too much. With a locker, that pressure relief is gone.

Putting all these things together, this is how I broke my axle.

Because of the increased now locked capability I was climbing a two foot step onto a very steep angle. Long story short, "T"ank "J"ammer slid back and fell off the angle/step. On the forth attempt/repeat of falling off, and no open differential to act as a pressure relief, I snapped my axle.

Snapping the axle showed the quality material the Powertrax Lock-Right is made from. NO damage to the locker minus cosmetics.
