To lock or not to lock the rear?

[Skinny]

I think wheel speed is probably one of the biggest causes for Gov Bomb explosion. Let's face it, the average consumer doesn't understand how to make it work and how it simply wants to explode if you mat the throttle.

I've had lock rites in other vehicles with decent luck but they absolutely suck in terms on streetability and smoothness in operation. I did enjoy the look people gave me when I came into a parking lot, clutch in, full speed ahead CLICK CLICK CLICK CLICK CLICK

IMO, a detroit in a heavy fullsize with an auto trans will be pretty seemless in all regards for what it is. Of course you do get the occasional ratchet in a straight line which is just the Detroit telling you it's still back there. That and it's a reminder to check your tire pressure

Well you guys are giving me alot to think about, i'm really considering the grizzly locker. I still have about 2 weeks before start getting the axles into the truck, so I have a little time to think about it. I have the Dana powerlok back together and ready to go into my front Dana 60. In the mean time I'll be cleaning, painting and assembling the axles before installing them. The 14 bolt is getting all new bearings, seals, and brake components. The dana 60 will getting new seals and a full king pin rebuild.

Grizzly would be the way to go IMO. I work for a performance retailer and that is probably one of the most popular choices (up there with the detroit unit). And it also has a pretty killer warranty if thats a concern or not..

 

[welpro222]

The warranty is nice, but its no good when it breaks deep in the woods. I have read that the grizzly is stronger and has better street manners.

My main concerns are:

Gov-lock- CONS are it may break, no traction above 25mph, weak carrier case and spider gears. PROs are its more streetable.


Locker- CONS are noise and lockup in tight cornering, PROS are its more traction in any situation.

My main concern is whats it going to be like driving up over a curvy mountain pass road fully loaded with hunting and camping gear. Wouldn't the locker be fully engaged going up a hill because your giving alot of torque?

 

[Skinny]

I drove an M1031 which I consider fully loaded all the time up Mt. Washington. At no point was I going, "this Detroit sucks!"

If anything, I would be looking at revising the steering.

 

[welpro222]

how would you revise the steering?

I second the Detroit locker. It is the best rear locker out there.
I have an Eaton e-locker in the front, fully open until you throw the switch. I would only put a selectable locker in the front.
When in the mud, its like driving a bulldozer, all wheels moving the same speed with the same power no matter the tire slippage.

When you need to turn sharper in some off road situations, it is nice to be able to turn the locker off and make the turn.

Stay away from the gov-lock. They belong in the 10-bolt not a 14ff or dana 60.
You would not put a 4 cylinder in a top fuel dragster!

cross over high steer with hydro assist is the only way to go.

need 4 inch minimum lift for this.

Agreed

Twin sticks help with a front locker if you cant get away from it. Stock push/pull sucks. Crossover really firms up road feel and response plus it maintains steering range throughout wheel travel. Hydro really helps as the stock system really struggles turning larger than stock tires in any situation.

I will be upgrading to a crossover steering setup in the future. I have all the parts for it, but I just need to buy the 2wd steering box.

 

[richingalveston]

get a steering box that is already ported. Then you can add hydro assist in the future without replacing the box again. it can stay capped until you install the other parts

 

[welpro222]

Can I order a steering box thats ported?

People over play the "manners" of true lockers like Detroits. I loved mine. I drove Big Ugly in Northern Michigan winters on 36" and 38" tires without issue.
