True Trac Diff??

Definitely superior to the trac lok or other clutch type traction unit. A spool is ideal, but questionable on the street, and opinions vary widely on the safety and axle reliability for their street use.

I replaced my trak lok with trashed clutches, on 40 or so runs (!) with a truetrack from Detroit Locker. Everyone I spoke to suggested it was second only to the spool in evenly splitting the torque at the track, and they a very reliable, though expensive. I had it installed, and it works great on the street, but have not had it to the strip yet, closed season and all.
