Review on Optimized Powertrax 9204302700 No-Slip Traction System for DANA 30, 27 Spline Open Axles by Reza Cook

You won't find a cheaper mod that gives you the performance of this locker. I bought it after failing to get past an obstacle on the trail and having to turn back. I wasn't willing to put a Detroit locker in the rear because of gear ratio issues. This frontlocker worked with current translations. This locker doesn't click or click at all. In 4wd it is 100% blocked and works fine. It was easy to install following the instructions that came with it. After installation, I got back on the trail and passed the previously difficult obstacle and cleared it with no problem. I highly recommend.
