The Powertrax Lock-Rite or No-Slip are full lockers which ratchet/disengage when making a turn off throttle but lock again once torque is applied. I have had a powertrax no-slip installed for 35000+miles w/32" and now 33" cant even tell its there except for the inside tire chirping when I make a turn as i am hard on the skinny peddle. Also if anything it saved my tires as i would smoke the inside tire when making a turn when i had a open diff. Any car/truck i get from now that will take one will have one installed. Ratchet type lockers are also to easiest to install basic hand tools and a couple of hours and your done.
