Ultimate budget Dana 30 build Jeep xj

Pretty straight forward
High pinion Dana 30 is slightly stronger than the lp Dana 30
hp dana 30 is a high pinion dana 30. High pinion gearsets are 1/4-1/3 stronger than low pinion gear sets. The reason they are stronger is because while driving forward, the gears mesh on the drive side (as apposed to the coast side). The result is much less gear deflection and housing flex, which will keep your gears from going boom. Also, high pinion axles have way more clearance under the driveshaft so you aren't spinning it on rocks.
A stock high-pinion Dana 30 out of an XJ is going to be marginally stronger than an XJ low-pinion Dana 30, but a low-pinion Dana 44 is going to have much more strength than a high-pinion Dana 30 for several reasons. The larger, 8 1/2-inch-diameter ring gear of a Dana 44 is going to have much more tooth engagement (surface area) than the 7.2-inch-diameter gear of the Dana 30, and tooth contact is going to play more of a role in strength than which side of the gear the engine torque is being applied to. This is why larger-capacity axles (Dana 60, 14-bolt, and so on) have larger-diameter ring-and-pinions to match.
The pinion gear shafts (another common failure site) are also different diameters. Dana 30s have 1.18-inch-diameter, 27-spline axleshafts that are smaller than 1.31-inch, 30-spline Dana 44 axleshafts. Those numbers might not seem significant until you realize that strength ramps up exponentially with every few thousandths of an inch in diameter. Axletube thicknesses can vary widely according to the age and application of both axles.
On top of all of this, there are aftermarket upgrades available that can beef up many different components of each axle, which further middies the waters for this discussion.
This is a long-winded answer to a seemingly simple question, but the bottom line is that many factors are involved in axle strength beyond just the ring-and-pinion or the pinion’s position relative to the centerline of the axle. Specific to Dana 44 axles, it is worth noting that the newer JK Dana 44s (and Dana 30s, for that matter) use pinions of significantly larger diameter than the older models. In fact, the diameter is equivalent to that of a Dana 60. As a result, Nitro Gear & Axle and a few other companies have released retrofit gears that allow standard-rotation Dana 44s to be upgraded with the newer and stronger JK-style ring-and-pinion sets. This is great news for any older Dana 44 applications, of which there are many among almost all of the OE manufacturers.
