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.

Fullspins 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.
