Hi All,

I have been searching all over for a true locker for the Sterling 9.75 that Ford uses in the F-150. I called ARB and Detroit. Both say that they have no plans to offer anything for this line. The limited slip that comes stock, I am told by Ford, gives at 120 ft/Lbs. For me and my applications this is worthless. So I am looking for a locker or some sort of posi-slip that will fit the 9 3/4 read end. Auburn has a product but I don't know much about it. Any suggestions would be great.

 

I have to ask who you talked to at detroit and ARB? Because both of them offer a locker for the 9.75 and have for several years. ARB sells an air locker and Detroit sells the TruTrac.

Thanks ford390gashog, looks like Detroits has it under a new product. It sure is great to learn new things here about our trucks.

 

Detroit is pretty slow about updating their website. It came out in 04 at the SEMA show along with the Toyota locker.

 

the auburn limited slip is awesome. i don't know the exavt numbers but i had it in my 150 and it was so tight powering around corners would sometimes ack lke a locker. i ran 31's what size tire do you want to run with the diff?

 

I have an '04 FX4 with Cooper STT 285/70/17 that I put on yesterday.

 

go to jawsgear.com(561 fro auburn) also have 2 others and look up for your truck you should have the 9.75 ford. the auburn would work for you. also auburn at tellico4x4.com for 464 i cann;t find the arb put is probably somewere.

 

Where did you buy your Coopers and how much did you pay for them??? I have been lookin for that exact same tire and size for my 97 and I cannot find them anywhere locally, 2 places locally can get them for 1100 bucks for me, I have fuond them for about 900 delivered on line. How do they drive on and off road, road noise?? Sorry not stealing your thread but I love the way those tires look and want them badly.

 

I purchased at a local tire factory in Bend, Oregon. I live 6 miles off paved road and between yesterday when I bought them and today driving--I love them. Going elk hunting back in Idaho next week and after I return I will do an update on how they performed.

 

Cool I would appreciate it. Do you mind telling me how much you paid also?

 

So I paid just at 1000 for mount, balance and siping.

 

Yeah thats the gion rate here in South Carolina, that is at the places that can get them. Tire Kingdom and a seperate local chain that carrys cooper neither of them have even heard of the STT and they are supposedly linked up with cooper or something...
