CWTD 145/70-6 Front Wheel Assembly With 3 Stud Hubs
The CWTD kit includes two tubeless 145/70-6 tires mounted on 6-inch rims, designed for front-wheel setups on go karts, ATVs, quads, buggies, mini bikes, and drift trikes. It uses 3-stud hubs with approximately 78 mm bolt spacing and a 54 mm center hole. A left and right front steering knuckle set with a 17 mm shaft size is included. Best for front-end upgrades where a complete wheel pair with steering knuckles is needed. Limitations include the need to verify hub pattern against existing spindles before purchase.
Who it’s best for: builders needing an integrated front-wheel package that includes steering knuckles and compatible hub spacing for a 6″ front wheel. Choose this if you want a ready-to-install front end and your project matches the 78 mm bolt pattern.
Why chosen: It consolidates wheels, tires, and front steering components into one package, reducing the number of separate parts to source. This can simplify installs on compatible chassis.
Caution: Verify hub and spindle compatibility with your current front end to avoid mounting issues.
Go Kart Live Axle Hub 4″ x 4″ For 1” Shaft
This hub is sized for a 1″ axle with a 4″ x 4″ footprint and adds a 2-3/4″ hub length. It features a 3/4″ step-down and a 1/4″ keyway slot, with four lug nuts included. Made from thick metal for durability and long service life, it suits projects needing a robust live-axle hub. Best for projects with a 1″ shaft and a requirement for a step-down hub to fit an alternate wheel or sprocket arrangement. Limitation: the data specifies a step-down rather than a direct match for all 1” shafts, so check your exact axle diameter and sprocket setup.
Who it’s best for: DIY builders using 1” shafts who need a reliable, heavier-duty hub with a straightforward installation. It’s better for simple, straightforward axle conversions rather than complex multi-gear systems.
Togarhow 740mm Go Kart Rear Axle Kit
Package includes two wheels with tire, rim, and inner tube, plus pillow blocks, an axle assembly, a T8F chain, a sprocket, brake disc, and a brake master cylinder caliper assembly. The shaft measures 740 mm (29.13 inches) in total length, with spline-to-spline 452 mm and a shaft thickness of 22 mm. Tubeless 13″ wheel size with 6″ rim; the kit pairs well with mid-to-large go karts needing a full rear-end upgrade. Best for projects requiring a complete rear-wheel package with braking and chain components included. Limitation: assembly complexity is higher due to multiple integrated parts.
Who it’s best for: builders seeking a complete rear-end solution, including wheels, tires, brakes, and drive components for a more turnkey build or upgrade.
Amavoler Front Wheel Hub With Bearing
Made as an aftermarket replacement for Kazuma Meerkat 50, 50cc ATV, quad, and similar go kart models, this hub features a 15 mm inner diameter. The product notes emphasize confirming compatibility before purchase. It’s built to enhance stability and durability for ongoing use, with a metal construction designed to withstand regular riding conditions. Best for Kazuma-style machines requiring a 15 mm hub bore. Limitation: compatibility depends on specific vehicle models and hub dimensions.
Who it’s best for: owners of Kazuma Meerkat or similar models seeking a straightforward hub replacement that fits the 15 mm bore requirement.
PRO BAT 17mm Front Wheel Hubs Spindle
This 17 mm 3-stud front wheel hub is designed for most quad bikes, ATVs, and go karts using 6″ tires. The hub mounting holes span about 78 mm (distance center to center). It is made from steel alloy, forged and heat treated for better finish, bearing hardness, wear resistance, and strength. Best for common 6″ tire applications where a solid, standard hub is required. Limitation: check exact spindle size and mounting alignment for your chassis before buying.
Who it’s best for: builders needing a reliable, widely compatible 3-stud front hub for standard 6″ wheel setups.
HuashenWoo 4 Stud Front Wheel Hub With Hydraulic Twin Brake
Delivering a complete front-wheel assembly, this option includes a 4-stud wheel hub, steering knuckle spindle, and a 110 mm disc rotor with 12 bolts, paired with a hydraulic twin brake caliper. It comes pre-assembled with hydraulic cables (620 mm main and 560 mm secondary) for smooth stopping power. Best for riders needing strong front braking performance on 125cc–250cc go karts or lightweight ATVs. Limitation: hydraulic brake system setup may require additional line routing on some chassis.
Who it’s best for: riders prioritizing robust front braking with an integrated disc and caliper on a 4-stud hub platform.
Buying Guide: Key Considerations For Go Kart Wheel Hubs
- Hub pattern and bolt spacing: Compare the hub pattern (e.g., 3-stud, 4-stud) and bolt spacing (center-to-center) to your steering knuckles and rims.
- Axle diameter and shaft compatibility: Confirm the axle size (1″ vs 3/4″ vs others) and whether a step-down or adapter is needed.
- Front vs rear configuration: Decide whether you need a front wheel hub with knuckles or a complete rear axle kit with brakes and sprockets.
- Tire and wheel size: Ensure the wheel diameter and rim width match your kart’s fenders, frame clearance, and suspension geometry.
- Braking integration: If you require hydraulic brakes, verify caliper type, disc size, and hose routing compatibility with your chassis.
- Quality and durability: Look for steel or alloy components with appropriate heat treatment and corrosion resistance for off-road use.
- Installation complexity: Some kits include knuckles, brake parts, and gears; others are bare hubs needing additional parts to complete installation.
Frequently Asked Questions
- What should I check before buying a go kart hub assembly?
– Check hub pattern, bore size, axle compatibility, and whether the kit includes necessary mounting hardware and knuckles. - Are 3-stud and 4-stud hubs interchangeable?
– No, you must match the hub stud count to the steering knuckle and wheel design used on your kart. - Is a complete rear axle kit easier to install than separate components?
– Yes for some projects, as it provides a ready-to-mount system with brakes and drive components included. - Do these hubs fit all 6″ tires?
– Not universally; check wheel width, bolt pattern, and disc compatibility for each tire and rim combination. - Can I use aftermarket hubs on stock frames?
– Compatibility depends on exact spindle size, bolt spacing, and frame clearances; verify measurements before purchasing. - What maintenance is needed after installing a new hub?
– Regularly inspect bolts, bearings, and seals; lubricate where specified and check for play or uneven wear.
