Seismic 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 aluminium, with oversized bores that rock on axles.
