I am running the three helical gear unit that uses 31 spline axles. I chose this “lighter duty” TruTrac because I already have Strange 31 spline axles with C-clip eliminators. I called the Eaton tech line about running this diff. C-clip, less and was told no problem. Just do not install the spacer between the axles and do install the access plug and snap-ring. I was also told this unit is stronger than the axles. Driving, it feels like an open diff. but when I gas it, it spins both tires. I can not feel or hear any chatter like you get with slipping clutches and it launches straight.
You are correct, the heavier duty unit has 4 helical gears and requires 33 spline axles. I think they call it the T2.
