Seismic Tekton Precision-Profiled XT Steel Spacers
Premium 0.400-inch steel bearing spacers. 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
