Best Atv Rear Axle Kit for ATV and Go-Kart Builds

#1 · Best Overall

1. YC Yier Axle Kit

Best for: Complete small ATV rear ends.

Why it ranks #1: Its 28-inch, 710mm kit targets 110cc–150cc ATVs and includes a swingarm bracket, brake disc, 3-stud hubs and covers.

A 28-inch axle arrives with a swingarm frame bracket, brake disc, and three-stud wheel hubs, making the YC Yier kit a consolidated rear-end option for listed 110cc, 125cc, and 150cc vehicles. Its included covers and hardware keep several assembly components together rather than requiring each to be sourced separately.

The 710mm axle is paired with a rear swingarm frame bracket, which gives a buyer both the axle and its listed frame-side component for a small ATV, quad, go-kart, or buggy project. A brake disc, three-stud hubs, sprocket cover, and brake-disc cover are also included, supporting a more complete assembly workflow. The stated engine range is 110cc to 150cc; confirm the specific vehicle's rear-end arrangement before planning installation.

Skip it if you need four-stud hubs or a 32-inch axle; this assembly is 28 inches and uses three-stud hubs.

Choose this for a listed 110cc, 125cc, or 150cc ATV, quad, go-kart, or buggy when the swingarm bracket and brake components are useful. Its 28-inch length and three-stud hubs set important fit boundaries.

#2 · Brake Kit Pick

2. ANTUKO 32-Inch Axle Kit

• Weight: 19.62 lb

Best for: Go-karts needing included brakes.

Why it ranks #2: The 815mm assembly lists a 190mm brake disc, 428 sprocket with 37 teeth and brake master cylinder for go-kart and ATV builds.

A brake master cylinder comes with this 815mm ANTUKO go-kart rear axle kit, giving brake-system components a place in the same rebuild package. The listed 428 sprocket has 37 teeth, while the 190mm brake disc and 11cm four-hole hub measurement provide specific interface details for planning fit.

The 815mm axle is specified with a 428, 37-tooth sprocket and a 190mm brake disc, helping builders compare the drive and braking hardware with their planned setup. A brake master cylinder is named in the title, and the four-hole hub's diagonal measurement is 11cm. The listing also notes 30mm maximum axle thickness and 23- and 28-tooth spline counts; measuring the existing layout is important because the product is described as a modified part.

Skip it if you need a different sprocket specification or cannot match the listed 428, 37-tooth setup and hub measurements.

Pick this for a go-kart builder seeking an axle kit with a master cylinder, brake disc, and specified 428 sprocket. Compare its 815mm length, hub holes, and axle measurements with the intended installation.

#3 · Hub and Brake Set

3. SEBLAFF 32-Inch Axle Kit

• Weight: 19.55 lb

Best for: 32-inch axle assembly projects.

Why it ranks #3: This 32-inch assembly combines a 4-hole hub pattern with chain and brake components, and its listing advises measuring before purchase.

An 815mm axle assembly groups the shaft, hubs, chain, and brake components for a go-kart or ATV rebuild. SEBLAFF specifies a four-hole hub with an 11cm diagonal measurement, plus an 8mm sprocket and brake disc, giving buyers several concrete dimensions to check against their existing setup.

The 815mm shaft and four-hole hub's 11cm diagonal measurement help establish whether the assembly's length and wheel interface suit a project. An 8mm sprocket and brake disc, alongside 10mm flanges on both sides, provide additional component measurements for planning assembly. The listing describes the kit as having a good assembly structure and easy installation, but also notes that the axle can have a normal radian and asks buyers to measure before purchase.

Skip it if you cannot measure the existing setup or need a guaranteed straight axle; the listing notes a normal axle radian.

This suits a go-kart or ATV builder who can compare an 815mm assembly and its hub, sprocket, and flange measurements with the existing layout. The stated axle radian makes measurement an important fit consideration.

#4 · Longest Axle

4. SEBLAFF 44-Inch Live Axle

• Weight: 35.7 lb

Best for: 44-inch DIY rear-end rebuilds.

Why it ranks #4: The 44-inch, 1120mm live axle is suited to longer DIY builds and specifies a 530 chain, 37-tooth sprocket and 220mm brake disc.

A 44-inch alloy-metal live axle comes with a 530 chain and 37-tooth sprocket, making the SEBLAFF kit a component-rich option for DIY go-kart, ATV, quad, and drift-trike rebuilds. Its 220mm brake disc and 33mm shaft diameter help define the assembly's scale and hardware layout.

The 1120mm overall length and 33mm shaft diameter give builders dimensions to compare with a frame and bearing arrangement. A 530 chain with 74 links and a 37-tooth sprocket specify the drive components, while the 220mm brake disc and 90cm brake tubing provide brake-related details for planning assembly. Four-hole hubs use an 11cm diagonal measurement; the listed 34cm sprocket-to-flange position and 7cm sprocket-to-disc distance further clarify the layout.

Skip it if you need a shorter axle or different chain and sprocket dimensions; this kit specifies 44 inches and 530 drive parts.

This is for a DIY go-kart, ATV, quad, or drift-trike builder who needs a 44-inch axle with specified 530 drive and brake components. Check the axle length and component positions against the frame before assembly.

5. TJHSM 44-Inch Axle Kit

• Weight: 36.1 lb

Best for: Long-frame live axle builds.

Why it ranks #5: Its 44-inch assembly specifies a 530 chain, 37-tooth sprocket and 220mm brake disc, with a stated capacity above 500 pounds.

At 44 inches long, this TJHSM live axle assembly targets projects needing a substantially longer axle layout than compact kits. It includes a 530 chain and 37-tooth sprocket, while the 220mm brake disc and 11cm flange diagonal give builders concrete drive and wheel-interface details for a go-kart, ATV, quad, or drift trike.

The 1.12m axle and 33mm shaft diameter help establish the assembly's scale for a larger DIY rear-end layout. Its 530 chain, 37-tooth sprocket, and 220mm brake disc bring drive and braking parts into the package, while the 90cm brake tubing length adds a useful routing measurement. Four-hole hubs with an 11cm diagonal flange measurement define the stated wheel interface. The listing says the axle supports more than 500lb, but the vehicle layout still needs checking.

Skip it if you need a compact 32-inch axle; this assembly measures 44 inches and suits a longer layout.

This suits a builder of a go-kart, ATV, quad, or drift trike whose frame can use a 44-inch axle and the listed 530 drive components. Its length and 11cm flange pattern are key fit boundaries.

#6 · 4-Stud GY6 Fit

6. CWTD 32-Inch Axle Kit

• Weight: 18 lb

Best for: GY6 DIY rebuilds.

Why it ranks #6: The 810mm axle has 750mm wheel spacing, 4-stud hubs on a 110mm pattern and is intended for GY6 125cc and 150cc-style builds.

A 32-inch axle with 29.5-inch wheel spacing gives this CWTD kit a defined footprint for selected go-kart, ATV, quad, and buggy rebuilds. Its four-stud hubs use a 110mm diagonal bolt pattern and accommodate compatible 7- to 10-inch wheels, helping buyers match wheel hardware to a compact off-road setup.

The 810mm overall length and 750mm wheel spacing provide concrete measurements for planning a replacement or DIY assembly, while the four-stud, 110mm-pattern hubs specify the wheel interface. Compatibility is listed for GY6 125cc and 150cc-style builds, and the axle is 530-sprocket ready, giving those projects a stated sprocket configuration. Wheels are not included, so the kit's listed hub fit does not remove the need to source compatible wheels separately.

Skip it if you need wheels supplied or a different axle length; the listed kit is 32 inches and excludes wheels.

This suits a builder of a GY6 125cc or 150cc-style go-kart, ATV, quad, or buggy who needs a 32-inch axle and four-stud wheel interface. Check the 750mm spacing and wheel pattern against the intended build.

7. 91.SCS 32-Inch Axle Kit

Best for: CVT and GY6 axle builds.

Why it ranks #7: This 810mm assembly lists 750mm wheel spacing, 4-stud hubs for 7–10-inch wheels and compatibility with 530-type sprockets.

An included wheel hub carrier distinguishes this 810mm 91.SCS axle kit for DIY CVT and GY6 projects. Its 750mm wheel spacing and four-stud hubs set out the key layout, while compatibility with 7- to 10-inch wheels gives builders a stated range for selecting matching wheel hardware.

The 810mm length and 750mm spacing help a builder compare the axle layout with a planned go-kart, ATV, quad, or buggy chassis before assembly. Four-stud hubs are specified for 7- to 10-inch wheels, clarifying the wheel interface, and the kit is described as compatible with 530-type sprockets. Its listed engine applications include GY6 110cc to 150cc and CVT setups, connecting the axle and sprocket configuration to those builds.

Skip it if you need a brake assembly included; this listing specifies axle and hub features but no brake components.

#8

8. XIKOBY 36-Inch Axle Kit

• Weight: 7.28 lb

Best for: Keyed one-inch live axle builds.

Why it ranks #8: The 36-inch DIY shaft has a 1-inch diameter, 1/4-inch keyway and step-down ends, with fitment listed for go-karts, ATVs and quads.

A 36-inch live axle with a one-inch shaft and quarter-inch keyway gives this XIKOBY kit a clearly specified interface for DIY go-karts, ATVs, quads, dune buggies, and trailers. Its ends step down to three-quarter inch with fine threads, shaping bearing and sprocket connection decisions.

The one-inch axle rod and quarter-inch keyway specify the main shaft interface, while the step-down ends measure three-quarter inch and use 3/4-16 fine threads. Those dimensions help buyers match bearings and sprockets to the axle rather than relying on a general vehicle label. At 36 inches long, it is listed for multiple DIY off-road and trailer applications, including Manco, Murray, Yerf Dog, and ASW examples. Check component interfaces and overall layout before assembly.

Skip it if you need hubs or brakes included; the listing specifies the axle shaft and its interfaces, not those assemblies.

Choose this for a DIY builder needing a 36-inch keyed live axle with a one-inch rod and specified stepped, threaded ends. It is a shaft-focused option, so the project must account for hubs and brakes separately.

#9

9. ISEYEC Polaris CV Axle Kit

• Weight: 1 lb

Best for: Specified Sportsman CV axle repairs.

Why it ranks #9: This is a vehicle-specific alternative listing two CV axles and two wheel bearings for selected Polaris Sportsman models, not a live axle assembly.

Two CV axles and two wheel bearings make this ISEYEC package a multi-part repair kit for specified Polaris Sportsman applications, rather than a live rear-axle assembly. Its listed model-year fitment is extensive, but the explicit exclusions for Touring, X2, and 6×6 editions make exact trim identification essential.

The package includes two CV axles and two wheel bearings, allowing a buyer to source those listed repair components together. Fitment names several Sportsman 400, 450, 500, 570, and 800 applications across specified years, while the exclusions rule out Touring, X2, and 6×6 editions, as well as lifted vehicles. That distinction matters before installation: this is a model-specific CV axle and bearing kit, not a universal solid rear axle for a go-kart or quad build.

Skip it if you have a lifted ATV or a Touring, X2, or 6×6 edition; this kit excludes those configurations.

This is for a Polaris Sportsman owner whose exact model and year appear in the listed fitment and who needs CV axles with wheel bearings. It is not a live-axle kit, and excluded trims and lifted vehicles are key boundaries.

Listed on Amazon as: Rear Left or Right CV Axle & Wheel Bearing Kit for Polaris Sportsman 400 HO/450/500 HO/500 EFI/800/570 2006 2007 2008 2009 2010 2011 2012 2013 2014, 2 CV Axles and 2 Wheel Bearings

#10

10. EIMSOAH Steel Axle Kit

Best for: Steel ATV replacements.

Why it ranks #10: Its listing describes a steel ATV rear axle replacement but provides no axle length, hub pattern or specific vehicle fitment for comparison.

Steel construction is the clearest concrete feature of this EIMSOAH rear axle assembly kit, supporting an ATV replacement project where wear resistance matters. The listing also identifies a sprocket and sprocket hub flange, giving buyers named drivetrain-related components to consider when assessing a replacement assembly.

The steel material is described as robust and wear-resistant, which makes material durability a relevant consideration for an ATV replacement. A rear axle sprocket and sprocket hub flange are identified in the title, so the kit has specified sprocket-related hardware rather than being described only as a bare shaft. However, the supplied information gives no axle dimensions or vehicle model range; buyers need to establish whether the assembly's physical layout matches their particular ATV.

Skip it if you need published axle measurements or a named ATV model fitment; this listing identifies neither.

Consider this for an ATV owner seeking a steel replacement assembly with a listed sprocket and hub flange. The available details do not establish dimensions or model-specific fit, so those are essential boundaries for a purchase decision.
