Gain a significant competitive edge with the MFactory Helical Limited Slip Differential, available at Turner Motorsport. This Helical LSD delivers a smooth and consistent distribution of power to your BMW's wheels, optimizing traction on the street, strip, or track. It's an essential addition for any BMW enthusiast.

Curious about the LSD's role? Without it, your car effectively becomes a one-wheel-drive vehicle, supplying torque to the wheel with less grip. The Helical LSD changes the game by allowing both wheels to receive power while limiting the speed difference between them, in contrast to open differentials commonly found in most vehicles.

Key Features:

• 30-Day Feel the Torque™ Money Back Guarantee: An industry-first assurance that lets you experience the difference. Plus, it's backed by a Limited-Lifetime Warranty for your peace of mind.
• Forged and Cryo-Tempered: Engineered for extreme durability and longevity, ensuring it can withstand the rigors of competition-level drag racing.
• Advanced Shot Peening Technology: Enhances surface hardness, making it well-equipped to handle the shocks of competition-level drag racing.
• Maintenance-Free Gears: Bid farewell to special fluids or rebuilds associated with typical plate LSDs. It's designed for hassle-free ownership.
• Lock-Free Operation: Ensures there's no adverse impact on steering response.

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.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Engineered to perform, Powerflex performance polyurethane differential bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers. 

When it comes to gaining a significant advantage over your competitors, the MFactory Helical Limited Slip Differential (LSD) is your ultimate ally. This LSD offers a seamless and consistent distribution of power to your vehicle's wheels, allowing you to harness maximum traction and put the power firmly on the ground.

But what does an LSD do, you ask? Well, without an LSD, your car essentially operates as a "1-wheel drive," as it can't deliver torque to both wheels simultaneously. Instead, it directs torque to the wheel with less grip, highlighting the limitations of an open differential, which is standard in most vehicles.

An LSD, on the other hand, permits the wheels to spin at slightly different speeds by a limited amount, typically represented as a percentage difference. It's when the differential locks that both wheels receive power. It's important to note that LSDs function differently from locked differentials, such as those in off-road trucks, which supply equal torque and rotational speed to both rear wheels simultaneously, often causing handling issues.

Key Features:

• Crafted from imported Japanese SAE 4320 Steel
• Industry-first 30-day "Feel the Torque™" money-back guarantee, along with a Limited-Lifetime Warranty
• Forged, double tempered, and super sub-zero treated for unparalleled toughness
• Utilizes advanced Shot Peening technology to increase surface hardness
• Engineered to withstand the extreme shock loads of competition-level drag racing
• Advanced gear geometry designed using industry-leading software, delivering more power to the ground
• Exclusively uses the highest quality Brighton-Best Hardware
• Maintenance-free gears eliminate the need for special fluids and rebuilds associated with plate-type LSDs
• Ensures lock-free operation, preventing adverse effects on steering response
• Rated for up to ~1000 WHp

As part of the break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.

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.
