Competition Dana 60 front locker

[BigBadDodge]

How much of an advantage, if any, is it to have the front locked while sledpulling ? I am contemplating an ARB locker up front.

Good question but i was thinking about the OX locker.

I'm putting over 1,000 Hp through my ARB locker and haven't had any trouble. After taking one apart I can see why they are so popular with serious performers, VERY well built!

 

[BigBadDodge]

I am set on the ARB as its been proven in the Sled Pulling community, just trying to figure out how much of advantage it would be, as its pretty pricey, and I have other mods planned.

I have talked to a few other experienced sled pullers about this same issue. From what i found the only advantage to going to the lockers was to stop breakage of ring and pinion gears. No one seemed to think that there was an advantage to competing, other than the had less problems with breakage. I am still interested to hear others opinions on here that have installed lockers.

How would you break fewer ring and pinion gears WITH a locker?



I would think that the opposite would be true...

I would say the reasoning is so that you have 4 wheels pulling rather than just 3. With an open axle the wheel that will spin easier spins, the wheel with the most traction is just rolling along. With both wheels spinning you are assured the most traction you can get. Dean

EXACTLY !!! I tried a spool... . Definately NOT the way to go. I'm currently running a power lock.

I understand the reasoning as well, I guess what I was looking for is lets say somebody pulled without the front locker and continullay pulled around 200' but after he put the locker in continully pulled 210'



I also know there are several variables to sled pulling just wondering if anybody out there thinks they are pulling any farther simply becuase they added the front locker.

If you can come out in a given gear with 3 wheels spining then having all 4 should get you up to max wheel/ground speed faster before sled gets heavy wouldn't it??

I've been to enough truck pulls in the past to see that a locker in the front will get you more distance then not having one. If you watch the jessup Georgia pull its clear who's running a locker and who's not. I'm saving up for one,your right there expensive,but probably worth it.

 

[HoleshotHolset]

Okay... locker in the front/rear/x-fer case, etc. will give you more traction... that goes without saying.



BUT... . how would you break fewer ring and pinion gears WITH a locker?



I would think that you'd break more parts with lockers... . since you're getting more traction.

Its a never ending battle, if you throgh in the locker the weak point then becomes the stock axle, wich you can upgrade to the moser axle's where is the wink link after that I don't know ?

I'M running an EATON H-130 rearend with 1 7/8 axle shafts,and go through about 2 or 3 ring/pinions per season. The ring gear is 12" in diameter. Just a reminder that when you upgrade in one area you'll break parts in another. I'll be going with a ROCKWELL rearend next.

I think the spider gears are generaly what actually breaks first not the ring and pinion, the locker eliminates the spiders.

"I think the spider gears are generaly what actually breaks first not the ring and pinion, the locker eliminates the spiders. "



That's exactly what I was thinking. Gene was taking out spider gears left and right before the Detroit was installed in his Dana-80.



Anyone ever look into the axles out of the F*rd F-550's? I didn't see the truck, but a guy that lives near my old stomping grounds put one in his dually. He said the spring perches and everything lined right up... . I missed out on buying his low-mileage disc-brake Dana-80 by a week.



Aren't there rules in pulling that state that your axles have to be OEM?



Matt

 

[HillCountrykid]

The Dana's in the bigger Fords have a larger bolt pattern since the axle shaft is bigger. I've been told that's why Dodge went with the hybrid 80 (with 70 axle shafts), because they could'nt use the 8 x 6. 5" bolt pattern on the larger 80 shaft. I'm not sure how true this is though.

I realize my 440 in my '75 aint up to what you guys are running in you diesels, but here goes. I pulled with lockers front and rear(detroit rear,lock rite front, both dana 60's) and there is a large advantage over pulling with opens, especially if you guys run front wieghts, and get the front hooking good.



I have had no problems with the lockrite in my 60F, even with 1000# of suitcases on the front. I never had problems with the detroit in the rear either, but couldn't keep axels shafts together. 60 Rear shafts are only 30-31 spline 1 1/4" so they are relitivly easy to break. I switched to a 14 bolt with a limited slip,(with no axle shaft problems, larger shafts) but I sure miss the detroit.



I also used the above lockrite in the front of my 93 until I got my 75 up and running. I no issues with it in the 93, and loved it when it was in the 93.

HOLESHOT,If you're asking me about the OEM axle rules. Our rules for Superstock say we can only run a one ton driveline or less,however the H-130 was stock in some of the 1 ton chevys in the late '40's thru '71 . Of course they were also used in heavier applications (the gray area of the rules). The H-110 is pretty much the same axle. Most of them we found have a 6. 17 ratio,and we have" LINCOLN LOCKERS" in them.

In a previous post you said you were going to use a rockwell rear end. I thought rockwells were 2. 5 ton ???
