New alternative to the Truetrac, introducing the lifetime warrantied Wavetrac http://www.wavetrac.net/index.htm
Moser has been working with a company called Wavetrac in developing a 9” 35 spline posi. Moser has installed them in several test vehicles, and it worked flawlessly at the track with good hard straight launches, and is a dream on the street. The unit itself weighs in @ 14.80 lbs, which is lighter than a 31 spline Truetrac @ 15.75 lbs. Moser has these units in stock and ready to ship. It does require the 3.250” case so any retro fits are looking at not only new axles but a new case. I will be adding them as an option to my Moser 9 inch rears, this unit is $460.00 more than a Truetrac. Bob

Oh well, if I come into some dough, I'll get another center and have 2 I suppose...

Wavetrac® Differential
Wavetrac® At A Glance:
• Innovative:
Patent pending Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.
• Customizable:
If desired, the diff’s behavior can be altered in the field to suit your needs.
• Superior Materials
9310 steel gears run in case-hardened billet steel bodies. ARP® fasteners used throughout.
• Maintenance Free
As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.
• Limited LIFETIME Warranty:
All Wavetrac® differentials include a transferable, Limited Lifetime Warranty.
WAVETRAC® in Detail:
Enhanced No-Load Bias Ratio via its Wave Design Center Pack
One of the known shortcomings of a typical torque biasing differential is its loss of drive (behaving much like an open diff) under zero or near-zero torque conditions (for example, when there is ‘no-load’ applied through the drivetrain, either at vehicle stationary and/or transition from engine driving vehicle to engine braking and back).
The Wavetrac® differential uses a patent pending design to improve grip in low traction conditions. Precisely engineered, converging/ diverging wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to each other, each wave surface climbs the other, causing them to move apart. This imparts an increased normal force through the side gears, increasing the bias ratio as a function of load. This increase occurs automatically only when conditions find it necessary, and it ‘reverts’ back to its nominal bias ratio quickly and seamlessly,
maintaining optimal drivability and performance at all times. It’s like having two differentials in one: you get the benefit of a higher bias ratio when needed without detriment to the car’s handling.
Here’s something else you won’t find in any other design:
The Wavetrac® diff’s behavior can be altered in the field to suit your needs. It comes standard with carbon-fiber bias plates for the best all around performance and lifetime durability. Interchangeable plates using materials with different friction coefficients to fine-tune the bias ratio are sold separately.
These bias plates provide a mechanism to tune the response of the differential as a function of applied torque load. The applied torque load manifests itself as an
axial load from the differential pinions into the housing. This axial force is then considered a normal force into the friction plate, and as a function of the effective provide a resistive torque to the rotational motion of the differential pinions. The resistive torque will add to the resistance of relative rotation of all components within the differential. The resistive force, however, is non-uniform since it is a function of the axial load from the differential pinions. The unbalance of the resistive torque will manifest as non-uniform energy absorption within the differential causing a bias ratio.
Designed from a clean sheet, the new Wavetrac® Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high.
Each Wavetrac® Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology.

That is good to know incase I get sick of my locker. Guys this is alot of money but if you broke a true trac and you had to buy another one because it was not under warranty you would have the same money into your true trac.
Bob do you have any info on the lifetime warranty as far as limitations?

bob so if i sent you the money today. this thing is for sale? lol
also what horse do you think it will hold. i hear of truetrac with 31 spline taking 750. will this with 35spline take 1000 or no?

Yes, it is for sale. I recommend the Truetrac for up to 600 rwhp, past that I've always recommended the locker or spool. I don't know what the Wavetrac can handle as far as ultimate horsepower, but with it using 35 spline axles it looks promising. Bob

From Wavetrac - Bob
What’s so different about a Wavetrac®?
Q: Okay, so Wavetrac® has a patent pending design, how does that help me?
A: To best understand how the Wavetrac® is truly different from the other gear differentials on the market, you
first have to understand the problem that the Wavetrac® solves:
Loss of drive during zero or near-zero axle-load conditions. What does this mean? This:
If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.
Why?
All gear LSDs (including Torsen®, Truetrac®, Quaife®, Peloquin, OBX, etc.) work in basically the same manner:
they divide the drive torque between the two axles as evenly as possible, applying drive to each side, up to the
available grip of each tire.
The amount of drive torque one wheel can get over the other is described as the bias ratio, a multiplier of drive
axle torque.
Standard, open differentials have a bias ratio of 1:1. They can only apply as much drive torque as there is available
traction at one wheel. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). All
your power goes out the slipping wheel - along the path of least resistance.
Torque biasing differentials offer an increased bias ratio over an open diff. For example, if a diff has a bias ratio
of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction
limit of the wheel with the least traction (slipping wheel). This is a significant improvement over an open
diff… most of the time.
The problem is that when one tire has LITTLE or NO grip, or zero axle-load, the other wheel gets ZERO
DRIVE, because (basic math here): 2.5 x 0 = 0.
Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side - that means that during
the time the wheel is unloaded, the typical diff will NOT power the wheel that’s still on the ground. No matter
how high the bias ratio, you get no power to the ground.
Aliso Viejo, California USA, April 24, 2009:
AUTOTECH Driveline is proud to announce the release of its latest Wavetrac® differential application:
56.309.176WK FORD 9 inch 35-SPLINE
Likely the first diff of its kind designed to fit the larger 35 tooth spline axles. Now, you don't have to suffer with
a substandard differential (or none at all!) when building your 35-spline rear end. The Wavetrac® limited slip
will give you two wheel drive without clunky or noisy locking mechanisms. The Wavetrac®'s internal gears are
made from 9310. It's body is machined from billet steel... it's built to last.
The new Wavetrac® is a helical-gear limited-slip differential, but unlike other gear differentials, the Wavetrac®
was designed from a clean sheet using state-of-the-art knowledge and engineering to be a better differential than
any other.
Better technology. Better performance. Better quality.

^^^^ so if i understand all that right.
a true trac. if i give it gas it will do it best to put equal power to both tires. so if one slips. they both bascily slip
now this will not do that.
also does this mean this will do fine giving it gas on a curve?
