Benefits of Limited slip Differentials (LSD)

How Does a Limited-Slip Differential Work?

A limited-slip differential (LSD) offers significantly more control over power distribution than a conventional open differential. While an open diff is designed to let wheels rotate at different speeds when cornering, it often sends power to the wheel with the least traction. This can be a major problem, especially in high-powered or performance vehicles.

Here’s what happens with an open diff:

When you apply throttle, the power takes the path of least resistance — which usually means the tire with the least grip. This results in wheelspin on the unloaded side, while the wheel with grip receives little or no torque. All your power can vanish in a cloud of tire smoke.

Now here’s how an LSD solves that: A limited-slip differential uses internal mechanisms — like clutch packs, cam ramps, or viscous couplings — to actively limit the difference in speed between the two wheels. When one wheel starts to slip, the LSD redirects torque to the wheel with more grip. The result? Better traction, improved cornering, and much more effective acceleration.

Why Clutch-Type LSDs Stand Out

There are several types of LSDs — viscous, helical, and clutch-type. At RacingDiffs, we believe the clutch-type LSD is the most efficient for both street and motorsport use. It offers:

• High performance and adjustability

• Custom preload and ramp angle setups

• Direct mechanical engagement

• Ideal for drifting, racing, and track days
