How do you tell if you have a dana 60 or an 8 3/4 with suregrip? Did 1974 scamps come with them?

 

backing plate of dana unbolts . 8 3/4 dosen't . no bolts .

 

Thanks! So is there any way to tell the difference from a regular backing and a dana 60 backing since they all have bolts? sorry for the noob question, I've just never messed with them.

thanks so much for the help guys. say I had a car that doesnt run how would I tell if it is suregrip? and If you had a 8 1/4 rearend would the punkin out of a 8 3/4 fit in it? Sorry I have no clue :\ I want suregrip in my roadrunner but I think I might know where a car is with it. thanks

 

Jack both rear wheels off the ground and rotate one tire by hand, if the other turns the same way it's a suregrip, if it rotates the other way it's an open diff.

 

Sure grips/posi/limited slip (anything with a clutch pack) wear out over time. Full spool is the way to go.

 

Depends on what you use the car for, it it's just a street car the spool will cost him an arm and leg in tires long before the clutch pac would have to be replaced. I've got one in my Cuda, but it see's limited street use.

The 3rd member isn't interchangable between housings, axles are different too.

 

NEVER for the street. One turn in the rain and the car goes in the ditch.

 

I wouldn't be running my car in the rain... then again, who knows where I would run my car with all the crazies out there.

Actually, since the LS would be locking both tires when you apply power, wouldn't you slide around in the rain anyhow? Not that we would be appling power while making a corner *cough*cough*.

 

No, that's an exaggeration.

 

Sure grips are not like spools. Spools lock both axles together and allow zero differential between axles. Sure grips on the other hand are limited slip meaning the axles will turn at a different rate while going around a corner but it resists the differential. For example if you are going around a tight corner with a spool in your rearend the outside tire is turning faster than the inside tire, with a spool both axles are locked perminantly so the inside tire will actually break traction and spin leaving all of the centrifugal force on the outside tire and 99% of the time its to much for the traction capabilities of 1 tire so the car will fish tail out of control( the rain would make it impossible to drive with a spool). With a limited slip the axles will be linked but when you go around a corner the clutch pack will allow the tires to turn at slightly differnt rates without letting all of the tourque through 1 axle.

 

Great axle ID chart dartcuda.

 

BS, you've obviously never diriven one on the street, in rain or shine. The only time you even notice the difference is when making a 90 degree turn at an intersection, and then the only thing is sometimes times the inside wheel will chirp a couple of times. I know at least 10 guys plus myself that run spools on the street and not one of us has had a problem. Yes, if you apply to much power you will fishtail, but that is just as true with a posi.

The difference traveled between the inside and outside wheel is very little on curve.

73, I just noticed your in Enderby, when spring hits I'll take you for a ride in mine down to Cutting Edge in Kelowna and introduce you to some other guys with spools.

 

It depends on how your driving if you want to take a nice easy trip to the shopping mall you will get a little chirp/wheel hop around the corners( wich I get with my sure grip anyway), if you try actually driving the car around sharp turns in the rain you will be in trouble. It is the same as the 35" tire barrier on weaker 4 wheel drives. Some people can run 37's on a dana 44 all day, but they dont spin the tires in mud bogs they treat it nice.

 

I guess I should withdraw some of my original reply. You can use spools on the street its not what most people do though. Sounds like fun your car sounds pretty mean.

 

If you do a lot of city driving, I can understand why you would want LS. If you do a lot more cruising, I would go with a spool.

The nice thing is, you can find what you want pretty cheap on E-Bay so if it not what you like, you didn't waste a ton of money.

 

i'd take the offer hehehe

 

The danger of a spool is not getting the car out of control if you "can drive." Any kid that's ever experimented on dirt roads should know that. The DANGER with a locker/ spool is if you break an axle. If you have enough HP and enough tire, the car and launch VERY abrubtly to one side There are several examples of this on Utube and other places on the internet. I was witness to a near tragedy on a dragstrip years ago

 

True, but wouldn't an open diff give you that effect if one tire spun a little and all power went to the other wheel? That's assuming that power even does go to both to start with, I'm not sure if it does or not.
