Seismic Fullspin XT Steel Precision 8 x 10mm Bearing Spacers (4 Pk)

Seismic Fullspin™ Precision-Profiled XT™ Steel Spacers 8x10mm. Machined from premium bearing steel and given advanced heat treatment, Tekton Precision-Profiled XT (Extra-Tough) Steel Spacers have extra-wide contact surfaces that square up against classic (non-built-in) bearings and align them far more stably than traditional thin-tube spacers formed of much softer iron or aluminum. The resulting optimized alignment means: Improved speed & acceleration; More consistent wheel contact & grip while cornering; More predictable slide release & hookup; Longer wheel & bearing life
