Qagea Wheel Axle Spacer Kit 13-Piece 3/4 to 1-1/8 Adapter Spacers, CNC Aluminum for Harley Bobber/Chopper

Qagea Wheel Axle Spacer Kit is a 13-piece set of CNC-machined aluminum reducer spacers engineered to adapt 3/4" inner-diameter axles to 1-1/8" outer hubs for Harley, bobber, and chopper wheel installs.

This kit gives builders and mechanics a reliable, lightweight way to match axle diameters to a variety of hubs without having to re-bore or replace components. Each spacer is produced from high-grade aluminum using CNC processes to hold tight tolerances and deliver smooth surfaces that seat against bearings, frames, or hub bores. The set includes multiple thicknesses so you can fine-tune wheel position and alignment during installation.

How do these spacers help when fitting wheels on custom Harleys?

The spacers permit smaller axles to work with larger hub openings, allowing reuse of preferred wheels or hubs on custom frames. They take up slack between axle and hub bore and provide a bearing surface that keeps components concentric.

• Adapts 3/4" axles to 1-1/8" hub or frame bores
• Prevents axial play by filling gaps
• Maintains bearing alignment for smoother rotation

Will installation require special tools or skills?

Installation is straightforward for anyone comfortable with basic wheel work: place matching spacers on each side of the axle between the wheel bearing and the frame or hub, then align and torque axle nuts or skewer pins to spec. No machining or permanent modifications are needed when the correct spacer sizes are chosen.

• Hand tools and torque wrench recommended
• Fits between bearing and frame/hub; no re-boring required
• Swap spacers to adjust wheel offset or alignment

What makes the Qagea spacers precise and durable?

Each reducer is CNC-machined from corrosion-resistant aluminum alloy for consistent outer and inner diameters with smooth mating surfaces. The precision cutting reduces the risk of gaps and uneven loading, while the aluminum keeps weight low—important for unsprung mass and handling.

• CNC machining for repeatable tolerances
• Aluminum alloy construction: lightweight and corrosion-resistant
• Smooth finish minimizes wear on bearings and hub bores

How do I choose the right spacer from the set?

Measure the axle outer diameter and the hub/frame bore, then select spacers that match the inner diameter and stack to the required total thickness for a snug fit. Use equal spacer thickness on both sides of the wheel to keep it centered; mix sizes to fine-tune offset when necessary.

• Confirm axle O.D. and hub I.D. before selecting spacers
• Stack spacers symmetrically for proper wheel centering
• Check axle nut or skewer engagement after installation

Who this is for: Motorcyclists, custom bike builders, and mechanics working on Harley-Davidson, bobber, and chopper projects who need a dependable, lightweight solution to adapt axle sizes and correct wheel fitment. Qagea's 13-piece spacer kit offers a practical option when reusing wheels or experimenting with different hub and axle combinations, and it includes two years of product protection against manufacturing defects.
