PowerTrax 9204352725 No-Slip Differential Lock | Dana 35 | 27-Spline | Trac-Lok | C-Clip | Case ID 1.626" | Compatible for Jeep Wrangler, Grand Cherokee, Ford Explorer, Ranger, Dodge Dakota, AMC

This was the only auto-locker, that I'm aware of, for the Dana 35 equipped with Trac-Lok limited slip (2000 Jeep TJ). Didn't really get much in the way of communication from the seller but the product still arrived on-time and was in perfect condition in factory packaging. The install was a little trickier than I thought. Basically I had to skip the instructions for the right side syncho/paddle and get them in seprately. Once I figured out that step it was a snap. The locker does have a brief break-in period where there may be some pops but that went away quickly and then had smooth operation. Off-road this things is awesome! I was instantly able to clear obstacles much easier. Huge improvement in off-road capability. I would not want to run this without upgraded axle shafts though! Only downside is that you will have to change your on-road driving habits. Quick turns/accelerations WILL lock up the rear axles and you will spin/chirp the inside tire. You quickly learn to "feather" the gas pedal on turns (from stop signs and parking lots).

BUYER BEWARE! This product lasted 2,000 miles in my vehicle before failing catastrophically. This was with light duty on road use only! On disassembly I found the PowerTrax to be a complete failure. When it failed a piece of the locker became wedged between the carrier and pinion gear, causing significant damage to the carrier, pinion gear, ring gear, bearings, and axles. Essentially every component inside the axle housing was ruined. PowerTrax refused to refund me for my failure, much less recoup for the expensive 100 mile tow bill and thousands it took to get my truck back on the road. Will not be recommending product or every using one again!
