Many others can't complain about the No-Slip, and having owned all three of the lockers already mentioned, MY No-Slip is least noticeable to drive. The Detroit chirps and clunks all over the place. My Lock-Rite was noisy with all its ratcheting noises. But my No-Slip in my B4000 has never given me problems, its quiet, reliable and provides 100% lock up when I need it. And I can't remember the last time I chirped a tire. But every time I drive my dad's jeep which has the Detroit, you can't NOT chirp a tire. And it clunks at weird times with a noise that makes you question whats going on in the differential. Can't say the same about my No-Slip.........
Experiences will vary, and in my case the No-Slip has served me well over the 30,000 miles of service that it has provided so far. I highly prefer it to the other lockers I've used.
To me its not what Power-Trax says, its what I have experienced. Seems like we've had this discussion before? Take it or leave it I'll stand behind the flawless operation of my No-Slip that has never let me down.
I still suggest the No-Slip for the original poster and his daily driver.
