I'm looking to upgrade the factory LSD in my sonoma to something more suitable for regular auto-X use. The truck has the 7.5/7.625 10 bolt with the factory G80 option and 3.42 gears with a mostly stock 4.3 and no immediate plans for big power.

Lock up with the factory LSD is unpredictable and more often than not the inside rear will let go on corner exits so I can't get any power down. The truck is still street driven but I auto-X quite a bit so I don't mind losing some street manners to cut some time on course.

Should I be looking for a clutch-type diff or helical gear-type like a Detroit Trutrac?
