When it comes to drifting, few components are as crucial as the limited slip differential (LSD). While tire choice, suspension setup, and driver skill all play important roles, the LSD is what allows consistent, controlled slides without losing momentum. Choosing the best LSD for drifting requires understanding how different types of differentials work, what their strengths and weaknesses are, and which applications they suit best.
This guide takes a deep dive into LSD options for drifting, explains their differences, and offers insights into which might be the best fit depending on your goals, vehicle, and budget.
Why the LSD Matters in Drifting
Drifting puts unique demands on a car’s drivetrain. Unlike grip racing, where maximizing traction is the goal, drifting requires controlled wheel slip. A standard open differential is a poor match for drifting, as it directs power to the wheel with the least grip. This leads to one tire spinning uselessly while the other barely contributes to propulsion.
An LSD, on the other hand, ensures that both wheels receive power. This gives the driver the ability to initiate, hold, and exit a drift with confidence. The LSD determines how power is distributed between the left and right wheels under load, and this distribution dramatically affects car behavior mid-drift.
Main Types of LSD for Drifting
Before selecting the best LSD for drifting, it’s important to understand the key types available. Each has unique characteristics that influence drift performance.
1. Clutch-Type LSD
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
Advantages
- Provides strong and consistent lock-up.
- Adjustable: the number of clutch plates and preload settings can be tuned for desired performance.
- Excellent for aggressive, competitive drifting.
Disadvantages
- Requires regular maintenance as clutch plates wear over time.
- Can feel harsh during daily driving due to its aggressive engagement.
This LSD is often considered the best overall choice for competitive drifting because of its predictability and tunability.
2. Torsen LSD
The Torsen LSD relies on gears to distribute torque rather than clutch plates or viscous fluid. Its name comes from “torque-sensing,” which describes how it continuously adjusts power delivery depending on wheel grip.
Advantages
- Smooth and seamless power transfer.
- Virtually maintenance-free compared to clutch-based designs.
- Works well for dual-purpose cars that see both daily driving and drifting.
Disadvantages
- Provides less lock than a clutch-type LSD.
- Can struggle in situations where one wheel has very little traction.
For casual drifters or those who need a balance between street comfort and occasional sliding, the Torsen LSD is a practical choice. However, professional drifters often prefer the more aggressive engagement of a 2-way clutch LSD.
3. Viscous LSD
Viscous LSDs use a fluid-filled coupling to transfer torque between wheels. When one wheel slips, the fluid thickens and directs more power to the wheel with grip.
Advantages
- Simple and low-maintenance design.
- Provides smoother engagement than a clutch-type LSD.
Disadvantages
- Engagement is delayed, making it less effective for drifting.
- Cannot provide the same level of lock-up as other LSDs.
Most drifters find viscous LSDs insufficient for serious drifting. They are more common in factory setups and are rarely the top choice for performance upgrades.
4. Welded Differential
Although technically not an LSD, welded differentials are worth mentioning. In this setup, the spider gears in a stock open differential are welded together, permanently locking both wheels.
Advantages
- Extremely cheap solution.
- Provides a 100% lock, ideal for drift initiation and maintaining angle.
Disadvantages
- Very harsh on the street; wheels skip around corners.
- Puts extra strain on drivetrain components.
- Unsafe in slippery conditions.
While welded diffs are popular among beginners due to affordability, they lack the refinement and adjustability of true LSDs.
1-Way, 1.5-Way, and 2-Way LSDs
Beyond the type of LSD, the lock-up pattern also determines performance.
1-Way LSD
- Locks only under acceleration.
- Good for grip driving, but not ideal for drifting since it offers little lock during deceleration.
1.5-Way LSD
- Locks fully under acceleration and partially under deceleration.
- A balanced option for drifting and street use.
2-Way LSD
- Locks under both acceleration and deceleration.
- Provides maximum control during drift initiation, transitions, and exits.
- The most popular choice for competitive drifting.
Choosing the Best LSD for Your Drift Car
Selecting the best LSD for drifting depends on much more than just brand reputation. It requires aligning the differential type with your goals, driving style, and budget.
Define Your Purpose
The first step is to be clear about your driving intentions.
- If your car will be a dedicated drift build, a 2-way clutch-type LSD is the most reliable choice. It offers predictable lock-up, essential for maintaining long drifts and executing transitions smoothly.
- If you plan to daily drive your car and drift occasionally, a Torsen LSD or a 1.5-way clutch LSD may provide a better compromise between street comfort and performance.
Consider Your Budget
- Entry-Level Drifters: Welded differentials offer an inexpensive way to get started, but they come with significant trade-offs.
- Intermediate Drivers: Investing in a quality Torsen or 1.5-way clutch LSD can balance performance with practicality.
- Serious Competitors: A 2-way clutch-type LSD is almost non-negotiable for competitive drifting, and while more expensive, it provides unmatched control.
Maintenance Expectations
Different LSDs come with different upkeep requirements.
- Clutch-Type LSDs: Need periodic fluid changes and occasional rebuilds to replace worn plates.
- Torsen LSDs: Largely maintenance-free, making them appealing for drivers who prefer less upkeep.
- Viscous LSDs: Minimal maintenance, but less effective for drifting, so not ideal if performance is your goal.
Vehicle Platform Support
Some vehicles have strong aftermarket support, which makes sourcing and installing LSDs easier. For example:
- Nissan Silvia, Skyline, and 350Z platforms have a wide range of clutch LSDs available.
- Toyota Supra and AE86 owners also benefit from extensive LSD options.
- BMW and Mazda RX-7 drivers often find high-quality 2-way LSDs tailored to their needs.
Choosing an LSD that integrates well with your platform ensures smoother installation and better long-term results.
Driving Style and Skill Level
Your skill level also plays a role.
- Beginners may struggle with the aggressiveness of a 2-way LSD and might prefer the more forgiving nature of a Torsen or 1.5-way unit.
- Experienced drifters usually demand the full lock and responsiveness of a clutch-type LSD, especially in tandem or competitive settings.
Installation and Setup Tips
Even the best LSD won’t deliver results if not properly installed and maintained.
- Professional Installation: Proper setup is critical. Incorrect backlash or preload can cause premature wear or failure.
- Break-In Process: Many clutch LSDs require a break-in procedure to seat the clutches properly.
- Regular Fluid Changes: Using high-quality LSD oil ensures consistent performance.
- Supporting Upgrades: Coilovers, angle kits, and sticky rear tires complement the LSD and maximize drift performance.
Final Thoughts
The best LSD for drifting isn’t a one-size-fits-all answer. It depends on your goals, budget, and vehicle platform. Beginners might experiment with welded differentials, but as skills progress, investing in a quality LSD pays off in consistency and control.
For dedicated drift cars, a 2-way clutch-type LSD remains the gold standard, offering unmatched predictability and lock-up. For dual-purpose vehicles, the Torsen LSD provides a smoother, lower-maintenance alternative that still delivers fun slides.
Ultimately, the right LSD transforms drifting from unpredictable tire spin into an art of precision and control. Choosing wisely ensures that every slide, transition, and exit feels deliberate—and that’s what drifting is all about.
