more Re-gearing discussion please

I am still on the fence

Planning  to regear and add lockers, (Hopefully before Christmas)....for my 3.6 Auto, d30, and staying with 35's will 4.88 or 5.13 serve me better?

I still plan to drive to rides and it does see some Daily Driving (so maintaining 70mph) to the mall and stuff... I tow a landscape trailer with kayaks occasionally but I don't think either of these gearing options will affect towing...

I have seen the charts but I might as well be looking at an abstract painting...they really do not make a lot of sense. To me.

Thoughts?

If you're daily driving it, 5.13 is way too much gear.  I'm running 4.88 with 37's it is the right gearing for DD and trail duty.

I have plans for 4.88, although Doug will tell you you can never have too much gearing. For my purposes I'm just trying to decide how long it will be before the D44 front end swap. And how long I'm willing to wait......


If you were running with the 3.8L you might consider 5.13, but I would think the 4.88 should be plenty unless you're going up to 40's at any point.

With the way aftermarket axles have started dropping i would definately consider a 44 front before i would regear and lock a dana 30. Just save your money a little longer.

The dynatracs are 6500 which is still pricey but then you get a 35 spline rear with new axle shafts.

the ultimate 44 is another less expensive option. At 3 grand this around 1500 to 1800 over what you would have into a locked and regeared 30 if you use a selectable locker.

I respectfully disagree with DOUG. You van definitely have too much gear on the road. Use the chart and pick wisely.

Completely agree with Sam. Don't build a D30. Save for a D44.

Don't forget that you can also sail your front to recoup some of the cost

How much of a market is there for a D30 front?

Find the guy who bent his housing and can't afford a new axle. He'd pay $500 for a whole setup

I ran my D30 for a long time on 35's with 5.13 gears, never having an issue with stock shafts,  alot is in how u wheel.  at the start i had no plans to go larger than 35's and if thats the case, the 30 will serve u well, just add some gussets and your good.. cheaper than a PR44.  and will last, lots of guys running D30 with no issues.  the 44 was due to the Trump Pitbull tire deal, 37's.  just wanted more strength for the larger tires. 

dont get over sold on the D44 plenty of guys run D30 with 35's and have never had an issue, unless ur hard on the skinny pedal u should be fine for a long while.   just my .02 and experience.    i actually ran it, wheeled it, no breakage.   the 5.13 gears are tiny for a D30 but 4.88 would be just fine IMO.

I think regearing the d30 is wise. I don't know if I would throw too much money at the 30 if you want the 44 in the end. If you think the D30 is where you want to stay, then locking and trussing is definitely a good idea on that route.

Here is a link to the D44 that I bought through Northridge. Pretty much a bullet proof pro rock 44 for 5k

I might not agree often with Kent, but this time I do.
