MOOSUN Torque Converter Clutch Kit for Comet TAV2 — 1" Bore, 10T/12T Sprockets, Complete Bolt-On Upgrade

MOOSUN Torque Converter Comet Clutch Kit is a complete bolt-on replacement for Comet TAV2 series clutches, delivering smoother acceleration, improved low-end torque and higher top-end speed for 1" horizontal-shaft small engines.

This all-inclusive kit replaces Comet TAV2/Torque-A-Verter models and converts centrifugal clutch setups into a torque-converter-driven system compatible with many small engines (Briggs, Honda clones, Kohler, Lifan, Tecumseh and more). It comes with both drive and driven pulleys, belt, aluminum engine-mount plate, an integrated jackshaft with sprocket, mounting hardware, and easy-to-follow instructions. Two sprocket options (10T for 40/41 chain and 12T for 35 chain) are included so you can match your go-kart or mini-bike’s drivetrain without hassle.

How does this torque converter improve takeoff and acceleration?

Replacing a centrifugal clutch with a torque converter shifts more torque to the wheels at low speeds, giving stronger, more controlled launches and steadier power delivery through the RPM range. That results in less stalling, reduced belt slippage, and a more usable power band for hill-climbing and quick starts.

• Provides increased low-end torque for better launches and hill climbs
• Smoother acceleration across the RPM range
• Reduces burnout and wear on centrifugal-clutch systems
• Includes matched belt and pulleys for optimal engagement

Which engines and vehicles will this kit fit?

The MOOSUN kit is made for horizontal-shaft small engines with a 1" (24.5mm) driver-clutch bore and fits Comet 30-series applications. It's suitable for a wide range of machines from recreational to utility, provided the engine and chassis layout accommodate the included mount plate and jackshaft spacing.

• Fits Briggs & Stratton, Honda clones, Kohler, Lifan, Robin, Tecumseh and similar engines
• Designed for go-karts, mini bikes, mini choppers, ATVs, small tractors, lawn tractors and waterski winches
• Driver bore: 1" (24.5mm); driven pulley overall diameter: 6"
• Includes sprockets for 40/41 chain (10T) and 35 chain (12T)

What does the kit include and how easy is installation?

This package contains everything required to swap your centrifugal clutch for a torque converter system: drive and driven clutches, belt, machined aluminum engine mounting plate, jackshaft with sprocket, and all hardware. The components are engineered to bolt onto standard Comet TAV2 pattern setups, making the upgrade straightforward for home mechanics with basic tools.

• Complete set: drive clutch, driven clutch, belt, jackshaft, sprockets and mount plate
• Hardware and instructions included for a bolt-on replacement
• Engine mount plate simplifies alignment and spacing on horizontal shafts
• Dual sprocket options let you adapt to existing chain sizes

Will switching to this torque converter affect maintenance or longevity?

Using a torque converter can reduce heat and wear that commonly shorten centrifugal clutch life, but it introduces additional components that should be inspected periodically. Regular checks of belt tension, jackshaft bearings, and sprocket alignment keep the system running smoothly and extend service intervals compared with worn centrifugal clutches.

• Less frequent clutch overheating compared to centrifugal units
• Requires periodic belt and sprocket inspections and tension checks
• Replaceable components make repairs inexpensive and simple
• Preassembled jackshaft reduces installation variables and wear points

Who is this for: The MOOSUN Torque Converter Comet Clutch Kit is ideal for enthusiasts and small equipment owners who need a durable, performance-oriented upgrade from a centrifugal clutch. It suits DIY mechanics, go-kart racers, mini-bike builders, landscapers with small tractors, and anyone wanting stronger low-end torque, smoother power delivery, and a flexible drivetrain with included sprockets for common chain sizes.
