75W90NS is designed for synchros and shifts well. It is also GL5 rated. I am now curious how it compares to the beloved rearend grease called Shockproof. I am due for a change so I may try it.

Remember not to put Shockproof products in the rear end. It doesn't play well with your LSD. Turns to sludge instantly after you drive off. Shockproof was never designed for differentials anyway, it's for racing gearboxes subjected to high impact stresses. Hence the name and the lack of GL5 wear protection.
