Why Upgrade to Wolf Tooth Precision Headset Spacers?

The Wolf Tooth Precision Headset Spacer Kit exists because stacking mismatched spacers is sloppy and imprecise. Machined in Minneapolis from CNC-machined aluminum, this kit includes 3mm, 5mm, 10mm, and 15mm spacers so you can hit your exact stack height without guesswork. Laser-etched length markings on the end of each spacer mean you always know what you're working with, even mid-build when spacers inevitably get mixed up on the workbench.

Available in a wide range of anodized color options, these spacers are the cleanest way to customize your cockpit while keeping everything precise and intentional. The four-size kit covers virtually any fit adjustment scenario, making it a go-to for bike fitters and home mechanics alike. They pair perfectly with Wolf Tooth's stem caps and other cockpit components for a cohesive, dialed look on any build.
