Is there a difference between a trac-loc and a power-loc?
Is there benefits of 35 spline axles over 30 spline?
Also, I was using a pinion snubber,adjusted 3/4 from floor.I know a lot of you are against them.
What will I do in place of one?I have extra heavy duty leaf springs under the car which I cannnot afford to replace right now.



Powerloc has the clutches in the Sure Grip unit and is rebuildable and arguably will transmit more torque through it before slipping, compared to the Tracloc, which has the cone type sure grip that is not rebuildable (although it can in certain instances be remachined to work again).

The 35 spline axles are stronger due to the increased surface contact of the splines compared to the 30 splines. The 40 splines are stronger than the 35 and so on.
35 splines are very adequate on many very high torque/horsepower applications. Just do regular maintanance check ups on them for twist and if there are any problems peeking around the corner, you can usually catch them before they bite you.
