Ultra Light, Ultra Fast UniClutch Flywheel for LS Motors
For gearheads and performance enthusiasts with Chevy LS-powered rides, the UniClutch Ultra Flywheel UCFW-001 is a serious game-changer. Designed specifically to pair with the innovative UniClutch system, this ultra-lightweight flywheel promises to elevate the driving experience for street and track applications alike. Let’s dive into what makes the UCFW-001 a standout choice for LS motor builds.
What Is the UniClutch Ultra Flywheel UCFW-001?
The UniClutch Ultra Flywheel UCFW-001 is an advanced, purpose-built component engineered by Clutch Industries, an Australian company with over 70 years of clutch manufacturing expertise. Unlike traditional flywheels, the UCFW-001 is designed exclusively for the UniClutch system—a modular, patented clutch setup that redefines performance and adaptability. Tailored for Chevy LS motors (LS1, LS2, LS3, etc.), this flywheel is part of a broader ecosystem to reduce weight, improve response, and enhance durability.
Weighing in at a featherlight 15.4 lbs (approximately 7 kg), the UCFW-001 is a significant departure from the stock dual-mass flywheels found in many LS applications, which can tip the scales at 22 lbs or more. This reduction in rotational mass is a big deal for LS owners chasing quicker revs and sharper throttle response.
Key Features and Specs
- Material: Advanced Chromoly Steel Alloy
- Offers an exceptional strength-to-weight ratio, ensuring durability without the heft.
- Weight: Approximately 7 kg (15.4 lbs)
- Lighter than OEM LS flywheels, reducing moment of inertia (MOI) for faster engine response.
- SFI Approval: Certified to SFI 1.1 standards
- Meets rigorous safety requirements for racing applications.
- Integrated Starter Gear: Built-in and engineered for longevity
- No compromise on startup reliability, even with the lightweight design.
- Compatibility: Chevy LS Motors (6-bolt crank pattern)
- Designed to bolt up seamlessly with LS1, LS2, LS3, and similar variants.
- UniClutch Integration: Requires specific UniClutch mounting kit and core
- Works only with UniClutch systems, not traditional clutch setups.
Why It’s a Big Deal for LS Motors
Chevy LS engines are legends in the performance world—affordable, versatile, and capable of monstrous power. But their stock flywheels, often dual-mass designs, prioritize smoothness over outright performance, adding unnecessary weight and inertia. The UniClutch Ultra Flywheel UCFW-001 flips that script.
By shedding pounds, the UCFW-001 reduces the moment of inertia (MOI), allowing the engine to spin up faster. For drag racers, this means quicker launches; for track drivers, it translates to snappier shifts and better corner exits. Even on the street, LS owners will notice a livelier throttle feel—perfect for those who’ve swapped an LS into a lighter chassis like a Miata or a classic muscle car.
What sets the UCFW-001 apart is its synergy with the UniClutch system. Unlike conventional setups where the flywheel provides the friction surface, the UniClutch core handles that job internally. This lets the UCFW-001 focus purely on being a lightweight mounting platform, cutting mass without sacrificing function. It’s a radical rethink of clutch-flywheel dynamics, and for LS builds aiming to maximize every ounce of performance, it’s a compelling option.
Installation and Requirements
The UCFW-001 isn’t a standalone plug-and-play part—you’ll need the full UniClutch package to make it work. This includes:
- UniClutch Core: The clutch assembly itself (sold separately).
- UniClutch Mounting Kit: Specific to your LS application, with bolts, spacers, and spline adapters.
The flywheel bolts directly to the LS crankshaft’s 6-bolt pattern, replacing the stock unit. Since it’s a single-mass design, you’ll ditch the dual-mass complexity but expect a slight uptick in noise, vibration, and harshness (NVH)—a fair trade for the performance gains. The UniClutch system’s patented dampening tech helps offset this, keeping it street-friendly compared to typical lightweight flywheels.
Performance Benefits
1. Quicker Revs: Lower MOI means the LS motor spins up faster, cutting lag between shifts.
2. Improved Acceleration: Less rotational mass lets more power reach the wheels.
3. Track-Ready: SFI approval ensures it can handle high-RPM abuse.
4. Versatility: Works with stock or modified LS setups, from mild 300-hp builds to 1000+ hp monsters (with the right UniClutch core).
Real-world feedback from LS owners is still emerging, but early adopters—like those swapping it into Toyota GR86s or Subarus with LS conversions—praise the reduced rev hang and sharper response. For Chevy purists, think of it as a modern evolution of the classic small-blocks potential.

The UniClutch Ultra Flywheel UCFW-001 is available through RestoMod.co.za, your go-to source for cutting-edge automotive performance parts in South Africa.
Potential Considerations
- UniClutch Dependency: You’re locked into their ecosystem—no mixing with traditional clutches.
- Heat Management: Since the friction surface is in the clutch core, heat dissipation relies on that assembly. While UniClutch claims robust performance, long-term track testing by LS users will tell the full story.
- NVH Trade-Off: Lighter flywheels mean more chatter, though UniClutch’s dampening softens this compared to barebones race options.
The Verdict
The UniClutch Ultra Flywheel UCFW-001 isn’t just another lightweight flywheel—it’s a bold step forward for Chevy LS enthusiasts. Pairing cutting-edge design with the proven grunt of LS motors, it delivers a noticeable edge in responsiveness and performance. Whether you’re building a street beast, a dragstrip terror, or a corner-carving track toy, this flywheel (and its UniClutch system) offers a fresh take on unlocking your LS’s potential.
For those ready to ditch the heavy stock setup and embrace something new, the UCFW-001—available at RestoMod.co.za—is worth the leap. It’s a package deal that could redefine your LS experience.
