Difference between OBX and Quaife front LSD - 3000GT/Stealth International Message Center

DoctorDex · 07-18-2008, 11:03 AM

Just wondering what the difference is between the Quaife and OBX LSDs. I know the Quaife is almost twice as much, but as far as quality how do the two stack up? Anybody have any experience with the OBX?

The Quaife is made more "sturdy", slightly heavier and generally "overbuilt". Not a technical explination, yes, but that's basically what Phil told me. I personally would spend the coin for the Quaife unit if you have plans for serious power. I think they both have warranties, but I haven't dealt with OBX at all, so I don't know if they are any good or not.

OBX = Ebay garbage usually. Quaiffe overs a lifetime warantee, even if its broken while racing it. Thats worht the extra coin to me.

My SL had a quaife LSD and it took a ton of abuse and never gave me any problems. I had pretty big tires on it too so it had lots of traction (265's), solid motor mounts and a stage 3 clutch and I'd do burnouts and launch the car hard and it took the abuse. Highly recommended if you're going to be making any power.

Quaife is the top of the line. It's a benchmark. It has an impecable reputation and comes with a limited lifetime warranty.

OBX copies a lot of Quaife designs, including this one. I have inspected every one of them, and added Loctite to the bolts that hold it together, just like Quaife does. I believe OBX will be able to stand the same abuse. It offers the same warranty.

I had both of them in my hands and visually you can't tell the difference between the two. I might very well try out an OBX in my vr4 with its new setup.

Do OBX and Quaife put out spec. sheets with regards to what materials and methods are used to make them? Is there any way of determining if they are indeed made of the same quality of steel, ie. 4340 etc.?

I just saw this on supercar website and I was wondering what the difference was myself. I have to admit I am kind of excited about it. I have a 95 base with a TT conversion so I was planing to buy a used Quaife from a member on the boards then a friend made me an offer on a 6 speed that I just couldn't refuse. Now I need a TT clutch and a AWD LSD. I just cant bring myself to put that trans in without a LSD. I put the install on hold because of the price of the Quaife hoping to find a used one for a good price. Now with the price of the OBX I'm thinking I might be a little closer to getting this thing in.

Okay, here is one reason why you might want to choose one over the other. Quaife appears to have a better finish on the gear teeth. It costs money to produce a better tooth finish, so it makes sense that it is more expensive. From my personal experience I can tell that Quaife provides a more smooth and consistent operation from the very beginning. OBX seems to be more aggressive initially, due to the initially higher internal friction, but after about a week of driving it breaks in, the gear surfaces smooth themselves out, and you cannot tell the two apart.

Still, no special break-in is required for either diff.
