Juggernaut Jugg-A-Verter Super 30 Series Torque Converter Kit

The Juggernaut torque converter is the high-RPM upgrade at the heart of this Jugg-A-Verter Super 30 Series torque converter kit, giving modified go-karts, mini bikes and other small-vehicle builds a performance-focused CVT system designed around a 3/4-inch crankshaft.

This complete 30 series torque converter kit includes the Super 30 Series 3/4-inch-bore Juggernaut driver, 30 Series driven pulley, asymmetrical drive belt, dual chain sprockets, back plate, torque converter cover and mounting hardware. The kit is designed for performance-oriented small-engine applications where a conventional centrifugal clutch may not provide the desired drivetrain performance.

Super 30 Series Juggernaut Driver

The Super 30 Series Juggernaut driver is designed for higher-RPM modified engines and is recommended for Stage 2 and higher engine combinations. It is particularly suited to modified 196cc, 212cc and 225cc-style small-block engines, with an application rating of up to 15 HP depending on the complete setup.

On a stock engine operating around 3,600 RPM, the Juggernaut is not expected to provide a performance advantage and may affect top-end speed. The driver is designed to show its benefits on engines capable of operating at higher RPM, with 4,000+ RPM being where the Juggernaut design becomes more relevant.

The Super 30 Series driver is compatible with 3/4-inch-bore 30 Series torque converter systems, allowing the driver to be used with compatible 30 Series driven pulleys, belts and covers.

Complete 30 Series Torque Converter Kit

This 30 series torque converter kit provides the major components needed for a complete CVT drivetrain installation:

• Super 30 Series 3/4-inch Bore Juggernaut Driver
• 30 Series Driven 5/8-inch Bore
• 12T #35 Chain Sprocket
• 10T #41/#40/#420 Chain Sprocket
• Asymmetrical Drive Belt
• Back Plate
• Torque Converter Cover
• Mounting Hardware

The included dual sprocket configuration gives you options for #35 or #40/#41/#420 chain applications. Verify your chain size, crankshaft dimensions, frame clearance and drivetrain configuration before installation.

Designed for Go-Karts and Mini Bikes

The Jugg-A-Verter is designed for go-karts, mini bikes and other compatible small vehicles using a 3/4-inch crankshaft. It can be particularly useful on live-axle go-karts and applications with larger rear tires, where the drivetrain places greater demands on the engine and clutch system.

Rather than relying on a basic centrifugal clutch, a 30 series torque converter provides continuously variable gearing as engine speed changes. This allows the drivetrain to multiply torque during acceleration and change its effective ratio as speed increases.

Asymmetrical Torque Converter Design

The Jugg-A-Verter uses an asymmetrical 30 Series torque converter design. The movable sheave uses an 18-degree angle while the stationary sheave uses a 2.5-degree angle, creating a combined 20.5-degree sheave angle.

The asymmetrical configuration positions the torque-sensing cam outboard and is designed to provide favorable alignment for the final-drive chain in many go-kart and small-vehicle installations.

The design also allows greater belt travel within the drive clutch at higher RPM. Under the appropriate operating conditions, the system can achieve approximately a 0.90:1 ratio, or 10% overdrive, providing additional top-end gearing potential.

Built for Higher-RPM Engine Combinations

The Juggernaut torque converter kit is intended for builders using modified small-block engines rather than completely stock, governed engines.

It is suitable for applications including:

• Modified 196cc engines
• Modified 212cc engines
• Modified 225cc engines
• Stage 2 and higher engine builds
• Performance go-karts
• Mini bikes
• Live-axle go-karts
• Small-vehicle racing and off-road builds

The stated horsepower capability can vary depending on the engine, vehicle, gearing and overall application. Proper engine and drivetrain matching is important when selecting a torque converter.

Installation & Safety

Before operating the vehicle, make sure the jackshaft nut is properly torqued. Do not overtighten the nut, as doing so can damage the bearing.

Do not operate the torque converter without a belt installed.

Proper belt alignment, pulley spacing, chain alignment and mounting should be checked before use. An impact is recommended for installation of the applicable components according to the supplier’s installation guidance. Improper installation can cause the torque converter to come apart and may result in injury.
