Helical Limited Slip Differential

Allows for traction at all times by providing the most power to the wheel with more grip. Unlike plate differentials (1,1.5,2-way) helical LSDs can supply different spin rates to each axle, like when cornering.

NOTE: For E39 M5 fitment, the axle stubs may need to be shortened/ground down slightly for proper fitment of this differential. Professional installation required!

The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth, consistent distribution of power to the wheels with the MFactory Helical LSD puts the power-to-the-ground and maximises your vehicle's traction. A must for any car be it street, strip, or track.

What this means for E39 M5 owners that already have an LSD is you have a plate differential that can burnout and only offer a single spin rate . The helical LSD allows each axle to spin at a different rate, requires less maintenance, and smooth out the connection of power to the wheels.
