I plan doing a SAS and also rear axle swap on my Dodge Raider V8 (386 hp, 397 lb*ft). At the moment I'm using 33" tires and original axles..., but this combination is killing half-shafts too often...

One option is to use Landcruiser HJ61 axles with lockers. Would these axles survive? I plan using 35"-38" tires.
Does anyone know the ring gear diameter, half-shaft diameter at spline and weight of axle?
