4.10 versus 4.56

Which do you think is better?

1. High pinion Dana 30 and Chrysler 27 spline 8.25 geared at 4:10.

Or

2. Low pinion Dana 30 and Dana 44 geared at 4:56.

Both sets will be locked front and rear. The 8.25 may get converted to 29 spline.

Also swapping in a Tera 4:1 with 2low if that affects any ones thoughts.

Will most likely be running about 6" of lift.

Re: 4.10 versus 4.56

Too many variables.
Tire size
Type of wheeling planned
Mods need to install the D44 (perches, shock mounts, etc.)
And the biggie...BUDGET.

The one thing you did not state tire size. But anyway a high pinion 30 with 4.56 and Dana 44 with 4.56 is the best. But being the. Choice you have to pick from do the lp 30 and 44

Oh by the way the 8 1/4 with 29 spline axles is a pretty strong axle. But limited aftermarket support.

What?
I've gears up to 4.88, ARB and Detroit Lockers. AlloyUSA and Revolution Axleshafts.....


There's plenty of aftermarket parts for the 8.25" axle.

Sadly there aren't any Elockers or C-Clip Eliminators, maybe someday though.

Re: 4.10 versus 4.56

30-spline D44 is marginally better 29-spline 8.25, but the HP30 is significantly better than the LP30. Probably break the 30 more often.

Currently 33s
3 to 4 Times a year. Blue black trails at Rauch creek or equivalent.
Dana 44 is totally clean now. I have removed all previous bracket tree. Need to weld on U-bolt illuminators.
I currently own both sets of axles. Trying to do install on minimal additional dollars

Re: 4.10 versus 4.56

Great thing about LP is you can tuck it up nicely at full compression if you're going for that lower center of gravity gig. Thats just my experience though. Pros about 4.10s are that they're a pretty thick cut gear. Would be hard to blow that. But as aforementioned, its all about what you're about.

Auto Tranny - 4.56
Manual Tranny 4.10

Regear the HP to match the D44.
Sell the other two axles to offset the cost.

Re: 4.10 versus 4.56

Is anyone taking into account that OP is in Virginia, wheels in Pennsylvania -- Gotta be a 4 hour drive

Is 33's geared at 4.56 comfortable at highway speeds of 75 - 80 MPH -- how about fuel economy with the higher RPMs?

I'm thinking 4.10 would be better for the daily driver/highway driving of everyday use -- sure 4.56 in the trails would be better but you have to get there 1st

I'm purely speculation -- I have my 1st XJ, want to run 33's but I like to travel north from NJ to NH -- About a 5 hour drive, most at highway speeds of 70+ MPH -- I'd love to hear some thoughts on this

With a 4:1 transfer case it will be a very capable rig on the trail. 4:1 in the differential may be a good choice for highway runs.
