Detroit Locker 8.8" 28 Spline Differential

* Fully Automatic Locking Action
* No Individual Wheel Spin-out
* Maintenance Free
* Legendary Durability
* Easy Installation
* Proven Design One Year
* Warranty

New preload devices between the side gears provide for a quieter and smoother traction control.

The legendary Detroit Locker began the revolution in performance differentials, and yet it still leads the industry. The Detroit Locker is still the most durable and reliable locking differential available. Detroit Locker maximizes traction by delivering 100% of the torque and power to both drive wheels. It is engineered to keep both wheels in a constant drive mode, and has the ability to automatically allow wheel speed differentiation when required.

No other performance differential has the reputation for durability of the Detroit Locker,delivering traction in mud, snow, dirt and over rocks and ruts.

Proven every week by demanding professionals in NASCAR, IHRA, NHRA, ARCA, CORR and other performance enthusiasts. The most rugged positive locking differential, and most widely available for axles from 3,000 to 70,000 lb. capacity.

For severe operational conditions. Driver may hear and feel "backlash" going from drive-to-coast and coast-to-drive, as reversing torque flow resets the components.

Eaton Detroit True-Trac 8.8" 31 Spline Limited Slip Differential

NOTE: 2005+ Mustangs Require Axle Spacer Modification

The Detroit Truetrac is a gear to gear limited slip unit that performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant. The limited slip unit responds instantly to torque feedback, anytime, at any speed.

Detroit Truetrac:
* Uses pairs of "Helical" gear sets
* Gears only - no clutch packs.
* Ideal for 4WD front axles or rear axles, as well as 2WD; light trucks, SUV?s, cars.
* Rugged yet smooth and quiet.
* Torque bias ratios of 2.5 to 3.5:1 range.

The Detroit Truetrac, manufactured by Tractech, is the aftermarket?s leading gear type limited slip differential. The patented design of parallel axis planetary helical gears provide a quiet, automatic splitting of torque. Power transfer goes literally unnoticed by the driver - even in front wheel drive axles. The Detroit Truetrac performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant. The limited slip responds instantly to torque feedback, anytime, at any speed.

Detroit Truetrac?s are engineered for front and rear axles, semi floating (C-clip axles) and transfer cases. Proven design, low cost and effective performance all make the Detroit Truetrac limited slip the choice of professionals and traction enthusiasts everywhere.

Great for off-road, street and strip.

The Detroit Truetrac delivers the traction necessary for drag racing and off-road terrain while not adversely affecting handling on the street.

A Locker is a mechanical unit that is sensitive to torque application. It will lock (drive both wheels) under acceleration, or unlock (allow the axles to turn at different rates) during coast or deceleration. A very strong piece, since it doesn’t use any clutches or cones that can wear out, which made it a good choice for it’s original truck application. Since driver input mainly determines whether the unit is locked or not, it can be very frustrating to a driver who is unfamiliar with the operation of the differential. Hard acceleration during a turn will cause the unit to lock and skid the tire. Between lock and unlock, a distinctive “clunk” can be heard. During a properly executed turn, clicking will be audible since locking teeth are allowed to jump each other inside the unit. Learn More

Similar in the design as the open, but have a series of friction plates between the side gear and the case. Standard Duty units have them behind one side gear, Heavy Duty have them behind both. There is a spring or springs that apply tension between the case, clutch pack(s), and the side gears . By increasing friction in this way, it requires more load variation before the clutches release and allow the gears to start rotating and speed-up the outer wheel. The number of plates, their material, and spring pressure will alter the release point. The clutch packs can be replaced when worn-out, but their replacement cost might be prohibitive.Learn More

A helical gear differential is a mechanical unit that, unlike the Locker, offers smooth and progressive power transfer. If one tire begins to slip relative to the other tire, a separating force is created between the pinion gears and side gears. This generates internal friction which slows the spinning wheel and sends power to the wheel with the most traction. These differentials are comparable to the strength of a Locker, but without it’s downsides. The Strange 9” S-Trac, due to materials and design, exceed the strength limits of the Locker while offering all the benefits of a helical gear unit.Learn More
