Any comments, is this a good choice? And what about 4.10 or 4.56 gears

 

If you insist on regearing, then REGEAR it. What I mean is the difference between the 3.73's and 4.10s is not enough to warrant spending the cash on 2 gear sets and labor for swapping them out.

Question... why don't you consider 4.30's. That would be the best of both worlds.

And Larry, My recommendation, FWIW, go with a detroit true trac. No parts to wear out or rebuild. I'm not a fan of any clutch or cone type limited slip. They only supply as much torque to the wheel with traction that the clutch will allow, where the truetrac will apply 3 or 4 times the traction available at the slipping wheel to the wheel that has traction.

I love the detroit locker. I have one in my f350, but its not for everybody.

Search my posts about the truetrac. I have one in my 08 F150. AWESOME flawless performance. And they can be used in front axles too.

 

Can I get 4.30 for the front? If you are recomending the 4.30 gears then there must be for some for the front. I hoped you would respond Driver444.
I have seen your post before.

 

Yeah, they're available. You have a Ford 8.8" front end (28 spline I believe). I'll admit, they're not as common as the 4.56 or 4.10, so you may have to do a little searching, but they are available. I believe motive gear and Yukon makes them.

In reviewing the tru trac I see that some reviews state that it is recommended not to run 35's ? is this an issue? or do I need to make sure I get a specific model that will handle the 35 size tire?

I also would love to run a tru trac in the front. Most of my off roading would be in the dessert. southern CA. Sand and sand dunes. Also Sand dirt roads.

 

I went with Yukon gears (4.56s), Timken bearing and the TrueTrac. You pay a bit more more for the Yukon's but they have the strongest rep.

The size limit spec on the True-trac is confusing. I was worried about this until I got mine and read the materials. The install/warranty docs with the unit said it was okay up to 38" tires (it could have been more, I just remembered when I saw the 37" were covered I stopped caring).

If you're going to have 4WP do the install then it's worth noting you can negotiate pretty much everything. I had mine bidding against another local shop for the work and 4WP ended up shaving $320 off the original quote (keeping the same parts spec). You can also negotiate a lifetime warranty with them. I paid $125 extra for each diff and that covers all parts and labor, including the truetrac, for life at any 4WP store (although there's not many 4WPs outside of Denver I would trust). Given I have a lead foot and do get off road fairly often it was worth the extra $250 for me for peace of mind.

 

I would only recommend a Truetrac up front for a true specialist machine. In normal driving the understeer would be huge and in slick conditions the vehicle would be nearly impossible to drive.

Check out pre-runner setups if you want desert performance.. it's a different beast. Many of those guys are actually 2wd.

 

I don't plan on racing around in the desert. I have had some nice trucks in the past. they worked great. I had an F350 4x4 with a built 460 and a 4" lift that truck was nice in the dunes and on the freeway. 36" dick cepec tires. too much to list. Any way this is a F150. the drive train is weaker. and I am trying to add what will make the truck work nice Just cruising around and exploring. With all 4 tires working I will be able to move around so much easier. I will be able to cruise throught the medium size dunes with no problem. I don't want to race up the giant Dunes! I have been away from the desert 8 years. This truck is something I have been saving for these last few years.

I thank all for there help.

I get strong advise towards two different limited slip setups. True trac and Auburn Gear. I still haven't made up my mind. Mika at 4 wheel parts is partial to Auburn Gear as he has had one in his F150 for nine years. He is offering me some smoking deals.

I also get real good deals from 4 wheel parts. especially after my Lift problems I went through with SO-Cal Suspension.
I have got to know the guys in the shop some what at my local 4 wheel parts. they seem to have good ability.

 

If you want front lockers then I'd go with a selectable locker setup. I don't have any direct experience to make brand recommendations though.

For the rear, I like the zero-maintenance design of the Truetrac. I haven't tried the Auburn, but I can tell you the Truetrack feels like it fully spools the axles within a quarter wheel turn of slip. It actually takes some getting used to in slick weather driving as you can kick the rear end out real easy.

 

I am told that the G2 set has a lifetime wty. I don't see Yukon gear sets offered by 4 wheel parts??? Must be why they push G2 as the better choice between what they carry.
From some of the stuff I have been reading. It looks like the two gear sets are comperable. the wty is the difference. Maybe I am seeing wrong.


4wheelparts is offering a 3 year 36,000 on the whole jobnot counting MFG wties
