Beefing up dana 30

I will be regearing soon soo i thought i would get an hp30. Since its gona be off the jeep i thought i might beef it up a bit. I have seen people weld trusses but i dont think i need a truss. My wheeling is sand and a bit of speed soo i do hit holes pretty jard ad get some air sometimes. Anybody has any recomendations of what i could?

Whether it's a HP or LP, a Dana 30 won't hold up to getting "air". Trussed or not.

The knuckles dont hold up? Or the tube itself? No way to solve that?

The Dana 30 just wasn't designed for such uses. There is nothing about it that is up to being jumped... the pumpkin, the tubes, the knuckles, the ball joints, the unit-bearing hubs, etc. You may get away with jumping it a few times but it's gonna catch up to you.

You need to set the bumpstops correctly...which is especially important for speed stuff, sand and bumps. As jerry said, the axle isn't designed for jumping...at all.

here's a fully build HP D30, with a beefy truss. it didn't survive getting air.

yes, it broke in half in the middle.

You somehow manage to insert bumpstop stuff into nearly every discussion. Just so TJ-Q8 isn't somehow mislead into thinking he can get away with jumping his TJ after correctly setting his bump stop height, the Dana 30 isn't up to being jumped no matter what he does with his bumpstops, adding a truss, etc.

because if you plan to drive the vehicle, you kinda need em

and to avoid misleading TJ-Q8, I did post of a picture of fully trussed HP D30 broken in half after getting some air. does that not show the D30 isn't up to jumps?

Bringing up correct bumpstop height adjustment was hardly germain to the discussion of if a Dana 30 can be made strong enough to be jumped.

I have several forsale in the non trussed variety

You can try a 44, but honestly I find them just barely a stepup over a 30. You could always put a 9" in it

Go to a local junk yard and find a ford 8.8... they are fairly cheap and very popular... then build that up. No sense wasting money on a dana 30 which will only let you down...

Not anymore extreme than a D60... I think the issue would be in being extreme...but moreso finding such a thing. Im not sure if they made 8.8 front ends, let alone ones that would work in a jeep. If they do make them, Ive never heard of them being put in a jeep.

Actually I believe the half ton trucks do use an IFS version of the 8.8, thats where most of the "high" 9 people get gears from.

So just for the record, there is a 9" Ford front axle? Because I'm assuming that's what the front Spider 9 is based on...
