So do people with D35s.
I'd hesitate to run 33's on a locked D35, especially behind a V8 in a heavier vehicle, but that's a personal thing. That's certainly not to say you
can't, but in terms of performance/strength envelope the 44A will have more headroom than the D35 at that tire size due to its internals alone.
Dana 35
Ring Gear Diameter = 7.562"
Pinion shaft Diameter = 1.376"
Ring Gear Bolt Count = 8
Pinion Spline = 26
Cover Bolt Count = 10
Axle Spline = 27
Axle Shaft Diameter = 1.09"
Dana 44A
Ring Gear Diameter = 8.5"
Pinion Shaft Diameter = 1.625"
Ring Gear Bolt Count = 10
Pinion Spline = 29
Cover Bolt Count = 10
Axle Spline = 30
Axle Shaft diameter = 1.31"
The 44A is not a bulletproof axle by any means, but as a bolt-in upgrade from the D35 for a couple hundred bucks it's a pretty decent unit.
