High pinion axles do you really need one?

[boxboy]

I was just wondering is a High pinion axle Dana60/44/30 converted 9" really necessary, given it weak points and limited gearing?

I think so--I used to rash the heck puta my drive shafts--now I never touch em :;

If I ever get around to doing a rear 60, I'm gonna convert a high pinion front to a rear :redneck:

No..

is that the HP axles or the better suspension setup? And do you think you could have put your COG lower with low pinions, did you raise other components for driveline clearance?

do you need to put something in your Rear? why High Pinion?

You've seen my rig

Link bars are the lowest components. Plus with high pinions you don't have to rotate your diffs as much for proper u-joint alignment and therefor getting better clearance under the diff...

 

[pokey]

having a high pinion front or rear raises your driveline for a little more protection. The real benifit however is the decreased driveline angle that you get by having the pinion higher. This also decreases the stress on u joints due to the shallower running angle and if you have a flexy suspension with a lot of drop that added relief gives you more operatinging angle on the ujoint without binding. HP rear axles are great for jeeps and short wheelbase rigs because of the shallow driveline angle gained.(since the driveling is short) on a longer wheelbase rig I doupt the added cost is worth it unless you do a lot of rockcrawling where your dragging the driveline over the rocks.

HP are only needed if the d-line angles warrant it...otherwise they are a crock of ****.

I've been running low pinion 9's for years now and never had an issue that a HP diff could of solved and I beat on my **** harder than just about anyone who's allready posted in this thread :redneck:

You want more proof...


...both Mauler and Tom both ran low pinion 9's

And are they still wheelin :stirpot:

What about running on the face of the gears don't you loose strength in the gears when using a high pinion in the rear?

What about being limited to what 5.38 or something like that? This doesn't seem to pose any issues?

i run a low p 9 in the rear of my cherokee, i also run a 231 with hd sye and hd d line with a cv and havent had any problems with d line angles, the only flaw is that my d line is in danger in rocks logs ect.

yes you do loose strength on a rear HP aplication but not any different than running a LP in the front.

I personally have no issues with needing lower than 5:38's

Give me a break...they both wheel circles around you in a rental hybrid yota

Tom isn't but that has nothing to do with axles

Mauler will be shortly :redneck:

Actually Tom will be wheelin shortly too! he will be running a 10 bolt in the nose to start mg: till he can locate a 60 front. :redneck: both he and Mall'er will be rollin on LP 60's. In my car I would run a LP rear if they offerd a prorock in low pinion application. the real need for HP comes from short wheelbase, too much lift VS driveline angle typical in jeeps with stock wheelbase. in the newer cars that we have you cannot run HP since the drivline hits the motor and other parts on full uptravel (all of the sudden everyone all of the sudden needs to jump). there Brad now you are no longer the guy that wheels the "hardest" in the thread. :flipoff: maybe the "most" but definaly not the hardest!:kiss:

That kicks ass :clappy:

Wheelin your little RC car around the shop with your gun show biatch don't count :flipoff:

Besides I haven't wheeled in two months :wtf:

At least for the TJ D30 front, I think a hp is the way to go for stock motors and under 35 inch tires. Plus they are so cheap and easily converted. The exta 30 percent strenth (they say) seems to make the difference. If I could do it again I would not have dropped a dime on the stock low pinion 30 and would have gotten a hp to hold me out for a real setup.

 

[CrustyJeep]

do you need to up something in your Rear? why High Pinion?

Already been said, but for clearance and DL angle. I figure why not, I'm not gonna break a 60, and if I can find a front housing for cheap (could be a BJ axle with parts missing), it would just come down to labor. Fun project.
