Fullspin^® High-Precision XT Steel Axle Spacers
Premium 2.5mm and 5.0mm Axle Spacers.
Set of eight (8) – four (4) in each width.
Fit standard 8mm axles only.

Fullspin’s unique High-Precision XT (Extra-Tough) Steel Axle Spacers are machined from premium bearing steel with advanced heat treatment for unmatched strength and toughness.

Widths are set to extra-strict 2.5mm and 5.0mm tolerances, to support highly-accurate custom wheel spacing on finer trucks.

Bore spec dialed to maintain exceptional straightness on finer axles. Wall thickness set to exactly match inner rings of finer bearings.* Radius reduced to bare minimum on spacer edges, for fuller contact and more stable alignment at bearing interfaces.

Position wheels far more precisely and stably than ordinary axle spacers – which are typically rough-cut from easily-bent iron or aluminum, with oversized bores that rock on axles.

* For best results, use with Seismic® Fullspin bearings, which have extra-wide inner ring contact surfaces that exactly match the axle spacer ends.

Fullspin^® Precision-Profiled XT Steel Bearing Spacers
Premium 0.400-inch steel bearing spacers.
Fit standard 8mm axles only.

Fullspin’s unique Precision-Profiled XT (Extra-Tough) Steel Bearing Spacers have broad flanged ends that square up against Classic (non-Built-In) inner ring surfaces with up to 67% more contact area – powering unprecedented Classic alignment precision and stability.

Design levels and steadies all working components of seated bearings far more precisely and stably than Classic spacers from other brands – which are typically rough-cut from thin-walled, easily-bent iron or aluminum, with oversized bores that rock on axles.

This is hands-down the most advanced Classic bearing alignment tech ever seen in the skate world, and it unleashes truly exceptional paired performance. Synergizes with working features in all high-quality Classic bearings* to maintain exceptionally consistent wheel contact and grip; support extremely predictable slide performance; and noticeably extend both wheel and bearing life.

Precision-machined from premium bearing steel with advanced heat-treatment for unmatched strength and toughness.

Spacer width set to extra-strict 0.400-inch tolerance, to support highly accurate positioning of paired bearings inside finer wheels with well-engineered hubs.

Radius reduced to bare minimum on spacer edges, for fuller contact and more stable alignment at bearing interfaces. Bore specs dialed to maintain exceptional straightness on finer axles.

* For best results, use with Seismic® Fullspin Classic bearings, which have extra-wide inner ring contact surfaces that exactly match the profiled spacer ends.
