What is a 1-way limited-slip differential?

A 1-way limited-slip differential primarily engages when the engine is under acceleration. This means it helps distribute power to both wheels during acceleration, improving traction. It typically disengages or has less effect during deceleration or coasting, offering a predictable feel.

What is the benefit of a front LSD on my Acura RSX or Honda Civic Si?

A front LSD can significantly improve your car's acceleration off the line and out of corners by ensuring power is sent to the wheel with the most grip. This reduces wheelspin and can lead to faster lap times and a more stable driving experience, especially on performance-oriented vehicles.

Does this differential come with all necessary installation hardware?

This product listing is for the Cusco RS 1 Way Front Limited-Slip Differential (Part # LSD 329 F) only. It is recommended to consult the manufacturer's installation guide or a professional mechanic to determine if any additional hardware or specialized tools are required for installation, as transmission disassembly is necessary.

About this part

Product Details

Cusco is well-known for making high-performance drivetrain components, especially for enthusiasts looking to get the most out of their vehicles. This front limited-slip differential (LSD) is designed to improve traction and handling for K20A and K24A powered Acura RSX (DC5) and Honda Civic Si (EP3) models. By mechanically biasing torque to the wheel with more grip, it helps prevent wheelspin during aggressive acceleration and cornering.

The RS model is a 1-way differential, meaning it primarily engages under acceleration. This design is often favored for its predictable behavior during spirited driving, helping to put power down more effectively when you need it most. It's a well-built unit that can make a notable difference in how your car launches and handles through corners, especially when paired with performance tires. Installation involves significant drivetrain work, including transmission removal and differential replacement, so it's recommended to have this done by a qualified mechanic.

This differential is designed to fit specific K-series engines and chassis. Ensure your vehicle is equipped with a K20A or K24A engine and is either an Acura RSX (DC5) or Honda Civic Si (EP3) to confirm compatibility. Because this is a critical drivetrain component, it's important to follow the manufacturer's installation and break-in procedures carefully to ensure proper function and longevity.
