Gaining a prominent edge over the competition is now within reach, thanks to the MFactory Helical Limited Slip Differential offered by Turner Motorsport. This Helical LSD ensures a seamless and uniform distribution of power to your BMW's wheels, significantly enhancing traction whether you're on the street, strip, or track. It's an absolute necessity for BMW enthusiasts.
Curious about the LSD's role? Without it, your car essentially operates as a one-wheel-drive machine, delivering torque solely to the wheel with less grip. This is where the Helical LSD shines, as it allows both wheels to receive power by limiting the speed difference between them, in contrast to the open differentials found in most vehicles.
Break-In Procedure: For optimal performance, it's recommended to change the fluid after the first 3-400 miles of use.
Please note that any defects or warranty claims should be directed to Team MFactory.
Upgrade your BMW's differential with the Differential Rebuild Kit Plus by Team MFactory. Whether you've recently replaced your differential or upgraded to a Limited-Slip, it's essential to replace the hardware to ensure optimal performance. This comprehensive kit from ECS Tuning includes 10 Differential Ring Gear Bolts, new axle seals, and new differential bearings, providing everything you need for a complete differential rebuild. With high-quality components, you can trust this kit to support your new differential or rebuild your existing unit effectively.

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 maximizes your vehicle's traction. A must for any car be it street, strip, or track.
What exactly does an LSD do you ask? Without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).
An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off-road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.
Features:
An industry first, 30-day Feel the Torque™ money back guarantee and a Limited-Lifetime Warranty!
Forged and Cryo-tempered
Advanced Shot Peening technology for increased surface hardness
Designed to withstand the extreme shock loads of competition-level drag racing
Maintenance-free gears eliminate the need for special fluid or rebuilds associated with typical plate LSDs.
Lock-free operation ensures no adverse steering response.
**As a break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.**
Includes $500 core charge to be refunded when we receive your rebuildable core.
