Limited slip options

Hi,
I'm sure this has been discussed but I want to add a limited slip/locking rear diff to my 03 4cyl 4X4. Pros/cons of different setups.
Thanks,
Tony

 

I know ARB makes a solid Locker...check this out

Do some research.....

There's a HUGE difference between a limited slip and a locker.

You need to decide exactly which one you want based on WHY you want either of them.

 

What Jan said-They are different and they don't usually come in the same package.

 

So do most people run them just on the rear of a 4x4 or is that something that would be run front and rear

 

Which...Lockers or Limited Slip??

Lockers- Both is handy but lots of folks get along with just the rear.
LSD- Usually just the main drive wheels.

but those are kind generalizations...You can do whatever you want.

 

My main use would be for traction in snow. I'm not into off road driving. I figure a locking diff would be best for my situation-driving up snowy roads. Is there a TRD locking diff that would fit my axle? I would like to stay with a Toyota offering if possible.
Thanks

 

Actually for snowy road use, I would rather have a limited slip. They both will help, but the locker set up is more for heavy off road use. Again, they both have overlapping benefits on or off road, but I would prefer LSD on road and locker off road. JMO.

Like NAAC3Taco said.....

For ON-ROAD traction in the snow, look for a limited slip for the rear axle. It will function 100% of the time while you drive without any input. PLUS - it'll continue to work even while in 2WD. They're operated via clutch paks inside the differential and overall much safer to use. They are 'silent' in a sense that the driver doesn't have to think about it.

A locker is something completely different and does not allow for slippage. They shouldn't be used while ON-ROAD but only in extreme offroad situations and in 4WD. Lockers can be fulltime or they can be engaged. Lockers change the driving/steering/road handling characteristics. If you don't know what you're doing - you can break mechanical components and put yourself in an unsafe situation while the locker is engaged.

 

Also, a locker in the rear is definitely not recommended for on road snow/ice conditions.

I had an international pickup with a locking rear diff. In the snow I had to be very careful not to spin into donuts when accelerating out of corners. Basically the locking diff will spin you around in snow so I think the limited slip would be your better option. Limited slip allows more control.

 

Thanks for all the replys. Sounds like limited slip is best for my situation. Is the best option to purchase the diff, pull my 3rd member and take it to a shop to be set up? Is limited slip on the front an option?

 

From my research it looks like the Detroit Truetrac is the best choice for front and rear. Thanks for all the input
