This hub is best for riders who need a robust, straightforward mounting solution on Predator 212cc or 196cc setups. Choose this if you require a reliable, mid-range heavy-duty option that can handle daily use and rough surfaces. A key limitation is the need to verify mounting hole spacing matches your sprocket: misalignment can prevent proper fit.
GREHUA Rear Steel Sprocket Drum Brake Hub
The GREHUA hub is a steel, 1″ bore with a 1/4″ keyway, designed for Predator 212cc/196cc and similar go karts. It’s notable for its complete hardware kit and easy installation process, making it a strong choice for DIY builds focused on durability. Best for riders who want a secure, drum-brake-ready hub with straightforward mounting. Limitations include ensuring compatibility with your specific kart model and brake drum setup.
RZEOZU 1″ Bore Sprocket Hub with 420 Split Sprocket
This aluminum rear wheel hub with 1″ bore and 1/4″ keyway is compatible with 420 split sprockets, particularly 42T. CNC billet aluminum offers durability, with carbon steel clamp-on collars for added axial support. Best for riders seeking a lighter hub without sacrificing strength, useful in lighter go kart builds or where weight reduction matters. A potential drawback is limited compatibility to specific hub and sprocket sizes, so verify fit before purchasing.

The RUIQIMOTO hub is a 1″ bore with 1/4″ keyway, made from high-quality 45# steel, and includes the sprocket hub plus screws and nuts. It fits Predator 196cc/212cc and other 6.5hp go kart carts. Best for builders on a budget who still want reliable mounting hardware and a straightforward installation. It may be less ideal for riders needing additional hardware variations beyond the included kit.
YOXUFA 60T Rear Sprocket Hub for 1″ Live Axles
This YOXUFA option provides a 60-tooth sprocket hub compatible with 1″ live axles, offering a higher gearing choice for go karts with Predator 212cc or similar engines. It is best for riders seeking more top speed or improved acceleration through larger rear sprockets. Note that it specifies 60T with a 2-1/8″ bore center hole, so verify the mounting hole distance and bore compatibility with your frame and axle setup.
Buying Guide
What bore and keyway size matter most?
Most go kart hubs use a 1″ bore with a 1/4″ keyway to align with common live axles. Confirm your axle diameter and keyway width before buying to avoid misfits or missed alignment, which can cause wobble or gear slip.
Which sprocket count is right for your driving style?
Higher tooth counts increase top speed but reduce acceleration, while lower counts boost torque and take-off. Match the sprocket teeth to your engine power, weight, and terrain. A common setup uses 42T–60T rear sprockets with 40/41/420 chain, depending on your chain layout.
Material choices: steel vs aluminum
Steel hubs offer durability for rugged off-road use and easier tolerances for heavy-duty applications. Aluminum hubs are lighter, which can improve handling on lighter karts but may wear more quickly under heavy loads. Choose based on riding terrain and maintenance preferences.
Hardware and installation considerations
Some hubs come with hardware kits, including screws, nuts, and wrenches. A complete kit simplifies installation and reduces the risk of missing fasteners. Ensure your sprocket holes align with the hub’s mounting pattern and verify necessary accessories match your kart model.
Compatibility with your kart model
Always check compatibility notes for Predator 212cc, GX160, GX200, and other engines. Sprocket hubs often specify engine compatibility, chain size, and axle type. If you are unsure about fit, contact the seller or compare mounting hole distances on your current hub.
Maintenance and inspection tips
Periodically inspect the keyway and bolts for wear or loosening. Clean dirt from the hub and sprocket to prevent accelerated wear. Replace worn components promptly to maintain smooth power transfer and reduce the risk of drivetrain failure.
