I'm pretty hard on the gas...a lot doubt the strength of a hp30. But it's much more stout than many choose to believe. Build it up. Slap good ball joints+wheel hubs and you've got yourself a squared away axle.

When i go to build up my d30 i might just use yours as a reference haha. Figure if it could handle 37s then 33s shouldnt be to hard on it

Don't confuse it though. There's a difference to having a built d30 vs a hp30

The jks are high pinions from factory.

Also. As a reference. Imped might have a more squared away hp30 than I. Haha

Ya the way the ring gear aligns with the pinion on the reverse cut is what makes it stronger

There is a good write up about it on the ranger station.com about those guys using them for a solid axle swap

Housing wall thickness is different as well (I'm talking about the YJ HPD30), plus ribbing.

Its a pretty good axle with good aftermarket support.

I polished my old HPD30 and it rarely let me down.

Eventually, the axle tube below the SOA perch cracked almost completely in 1/2. I ended up sleeving it externally & completely got rid of the vacuum disco housing, basically making my axle tube 1/2" thick - plus I trussed it as well.

Oh crap man why did you have to remind me how horrible my front axle is?

I read right over the high pinion part about 10 times. I said it to myself each time but it never registered that i dont have one haha

I think my mind just wanted to believe someone was running 37s on a LP d30

I recently bent my LP Dana 30 a couple months ago on 33s. I plan to build a HP Dana 30 with sleeves, gussets, and a truss, im hoping to fit 37s on it. Im not too worried, ive been doing a lot of research and HP 30 seems to be pretty stout, as long as your easy on it.
