3RD MEMBER LSD TYPE
100% brand new Ford 9″ complete replacement centre provides a transfer of power to the non-slipping wheel. Ideal for most street and performance applications. Torque is applied to the non-slipping axle through clutch action to limit wheel slippage. Made from Nodular Iron with long-lasting (Raybestos) clutches and precision assembly. As there is no clutch ‘pre-load’, the clutch will not chatter or cause the vehicle to pull when cornering.
This design ensures a positive, smooth transfer of power for maximum traction.

3RD MEMBER TRUE TRAC TYPE
100% brand new Ford 9″ complete replacement centre locker maximizes traction by delivering 100% of the torque to both drive wheels.
Ideal for most street and performance applications. 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 and is ready to install.

3RD MEMBER WAVE TRAC TYPE
100% brand new Ford 9″ complete replacement centre using A Wavetrac. Wavetrac® is truly different from the other gear differentials on the market. Wavetrac® solves Loss of drive during zero or near-zero axle-load conditions. Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is ‘no-load’ applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.
