It is not difficult at all. This is a photo of the adjustable clutch pack we make for the Oliver tractors. Super, and non Super. We made an axle that goes all the way through the brake pinion shafts, and attatch it solid on one side, and the clutch pack on the other. It is adjustable,, it can be a limited slip, or a full posi if you want it to be. It is under the brake housing, and to adjust, remove the brake cover, and tighten the adjustment nut to tighten the differential, and loosen it to make a limited slip. It does not affect the tolereance of the spider gears. That all remains stock. Hope this helps,, Chad

749.00 plus shipping. In my opinion,, something like this,, is just as important as a stroker engine. As long as the rules allow it. In our local club, it is not allowed, So make sure the rules will let you make this kind of modification. Chad

What is the reasoning for not allowing it in your local club? This would be an internal modification and no more of an advantage than stroking a motor, which is probably legal?

We have 3 different stages for this unit. it is related to clutch, and axle size in the kit, HP determines the clutch,and axle size. We have them in the V8 antique pullers, our stage 3 handles 650hp no problem. We would need your brake pinion shafts, the differential, and both brake hubs, and left side brake cover for machine work. Email me if anyone is interested in one. Makes a heck of a difference in a pulling tractor!!! Chad

If we sent you everything you need how long would it take to get it back? I pull an Oliver super 88/880.
