Locking Differentials

Fitting a locking differential to your vehicle can make a dramatic difference to the off-road performance, even when less aggressive tyres are fitted. We supply the tried and tested Detroit No-Spin and TrueTrac types. These are produced in the USA by Eaton.

The legendary Detroit No-Spin began the revolution in performance differentials and still leads the industry today as an Eaton brand. The Detroit Locker is the most durable and dependable locking differential available.

The Detroit Locker maximizes traction by delivering 100% of the torque 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. Applications are also available.

No other performance differential has the reputation for delivering traction in mud, snow, rocks and on the track. The choice of professional racers and off-road enthusiasts around the world! The durability of the Detroit Locker is unmatched!

The Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket as an Eaton brand. It remains the leading helical gear-type limited slip differential in the industry. Detroit Truetrac's proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well. Detroit TrueTrac differentials are avilable for 10 and 24 spline differentials.

TrueTrac differentials require a certain amount of resistance at the ground (i.e. traction) in order to start the torque transfer. A TrueTrac differential may not transfer torque if the spinning wheel is off the ground or on a very slippery surface. If spinning occurs, often a slight application of the brakes, while carefully applying power, will slow the spinning wheel enough to allow the TrueTrac differential to transfer torque to the other wheel. In low traction situations, like snow and ice the TrueTrac works very well. Unlike automatic lockers, which require a speed difference between the axles to lock up, the TrueTrac begins to transfer torque before any wheel slip occurs. In turns, a limited slip diff biases torque to both wheels, with a bias towards the slower turning inner wheel. An automatic locker puts all the torque on the inside wheel in a turn, as the outer wheel automatically unlocks. An open diff transfers torque equally, but combined with the extra steering load on the outer wheel, it may become overloaded and cause a push or understeer.
