Seismic Fullspin High-Precision XT Steel Axle Spacers

Seismic Fullspin High-Precision XT Steel Axle Spacers
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.
