Overview

This differential provides smooth and consistent power distribution to the wheels, enhancing performance on the street, strip, or track. It replaces open differentials, which can send power to the wheel with less grip, by allowing both wheels to receive power while limiting speed differences.
Show original supplier description
Gain a significant competitive edge with the MFactory Helical Limited Slip Differential from Turner Motorsport. It serves as a crucial upgrade for any BMW enthusiast looking to improve their vehicle's performance. Understanding the function of a Limited Slip Differential (LSD) is key. Without one, a vehicle effectively operates as a one-wheel-drive system, directing torque primarily to the wheel with less resistance. The MFactory Helical LSD rectifies this by ensuring both wheels receive power, limiting the rotational speed difference between them, a marked improvement over standard open differentials. Key features of this differential include a 30-Day Feel the Torque™ Money Back Guarantee and a Limited-Lifetime Warranty. It is forged and cryo-tempered for extreme durability, utilizing advanced shot peening technology to enhance surface hardness. The design also boasts maintenance-free gears, eliminating the need for special fluids or rebuilds common with plate-type LSDs, and features lock-free operation to prevent adverse effects on steering response. For optimal performance, a fluid change is recommended after the first 300-400 miles. Please note that any defects or warranty claims should be directed to Team MFactory. This differential is specifically designed for automatic transmissions only and requires a gear ratio of 3.15 or greater. It is intended for the BMW E46 chassis with an 188mm housing size.
