#5 · Longest Mid-Size

5. ANTUKO 32-inch Axle Kit

• Weight: 19.62 lb
• Dimensions: 33.07 x 8.66 x 2.76 in

Best for: 428-chain 32-inch rebuild.

Why it ranks #5: Offers an 815mm axle with a 30mm thickest section, 428 37-tooth sprocket, and 190mm brake disc for a mid-size build.

A 32-inch, 815mm axle paired with a 428 chain sprocket gives this ANTUKO kit a clearly specified drivetrain starting point. Its 37-tooth sprocket and 190mm brake disc help builders evaluate chain and braking components together, while the listed axle diameter and spline counts make measurement checks especially relevant before a replacement or modification.

8. Bruce & Shark 29-inch Kit

• Weight: 22.2 lb
• Dimensions: 27.56 x 13.39 x 5.51 in

Best for: Measure-first 29-inch replacement.

Why it ranks #8: Provides a 29-inch complete wheel-hub assembly, but the listing emphasizes measuring the original kit and supplies fewer clear specifications.

The 29-inch rear axle kit is paired with an installation video on its product details page, giving replacement builders a visual assembly reference. Bruce & Shark specifically urges buyers to measure their original kit and compare the dimensions shown in its product images, making size verification central to choosing this universal-style assembly.

This package is identified as a 29-inch universal rear axle assembly for go-karts, trikes, and drift bikes, so its stated category helps narrow the intended projects.

9. GLOSSY AUTO Rear Axle Kit

• Weight: 12.36 lb

Best for: T8F 58-tooth trike refresh.

Why it ranks #9: Its 740mm axle package lists T8F chain, 58T sprocket, 160mm brake disc, hubs, and caliper, but shaft dimensions are limited.

A 740mm axle paired with a T8F chain and 58-tooth sprocket gives this GLOSSY AUTO PARTS kit a defined drivetrain combination for a rear-end refresh. It also includes pillow blocks, hubs, a brake disc, and master-cylinder caliper assembly, enabling a builder to address axle support, wheel mounting, drive, and braking in one package.

#10

10. XIKOBY 40-inch Axle Rod

• Weight: 8.73 lb

Best for: Keyed 40-inch axle shaft.

Why it ranks #10: This 40-inch, 1-inch-diameter rod has a 1/4-inch keyway and stepped ends, but it is an axle shaft rather than a complete kit.

XIKOBY's 40-inch live axle uses a 1/4-inch keyway and steps from a 1-inch shaft down to 3/4-inch ends, giving drivetrain builders specific interfaces to match. The stated 3/4-16 fine threads and compatibility examples make this a shaft-focused option for kart, ATV, quad, dune-buggy, and trailer projects.

The full 40-inch length and 1-inch shaft diameter provide primary sizing references, while the step-down ends measure 3/4 inch with 3/4-16 fine threads. Those interfaces help buyers plan bearing, sprocket, and wheel connections around the specified shaft rather than selecting a complete wheel-and-brake package. A 1/4-inch keyway is included for keyed component engagement, and listed examples such as Manco, Murray, and Yerf Dog offer additional reference points when evaluating a replacement.

Skip it if you need wheels, chain, and braking hardware included; Togarhow's 29-inch package includes those rear-end components.

This XIKOBY shaft suits a builder assembling a 40-inch keyed rear axle around 1-inch shaft and 3/4-16 end interfaces. It is a shaft-focused choice, so plan other wheel, drive, and brake components separately.
