What is the main benefit of a 1-way limited-slip differential?

A 1-way LSD primarily engages when you are accelerating. This means it helps lock the rear wheels together under throttle, improving traction and putting power down more effectively when you are driving forward. It offers a more predictable feel during spirited driving and track use.

Does this differential come with all the necessary installation hardware?

This product listing is for the Cusco Type-RS 1-Way LSD unit itself. It is recommended to consult the manufacturer's installation guide or a professional mechanic to determine if any additional hardware, seals, or fluids are required for your specific vehicle installation.

What does 'Non-AYC' mean for my Mitsubishi Lancer?

AYC stands for Active Yaw Control, which is an electronic system some Lancer models use to manage rear wheel traction and handling. This Cusco differential is specifically designed for Lancer models that do NOT have this AYC system installed, as the factory AYC components can interfere with a standard LSD installation.

About this part

Product Details

This Cusco Type-RS 1-Way limited-slip differential (LSD) is designed for the rear of your Mitsubishi Lancer, specifically for models without Active Yaw Control (AYC). You'll receive the LSD unit itself, ready for installation. This differential is a significant upgrade for performance driving, helping to put power down more effectively during acceleration and cornering by locking the rear wheels together under throttle.

The Type-RS 1-way design means it engages under acceleration, providing a more locked feel when you're on the gas. It features a high initial torque setting, ranging from 14kg to 16kg, which contributes to a more immediate and predictable response. This is particularly beneficial for track use or spirited driving where consistent traction is key. The internal cone plate friction (PPFC) is set at 55/0, further tuning its engagement characteristics. Installing an LSD like this changes how the car handles, offering improved grip out of corners and a more direct feel from the drivetrain.

This is a substantial upgrade for any Lancer owner looking to enhance their vehicle's performance, especially if you plan on track days or competitive driving. It's important to note that this differential is designed for non-AYC equipped vehicles, so ensure your Lancer does not have that system before purchasing. Proper installation by a qualified mechanic is recommended to ensure optimal performance and longevity of the unit.
