Wrench & Bearing Kit

The QA1 Wrench & Bearing Kit (SKU QA17888-110) is a complete coil-over thrust bearing assembly designed for QA1 Economy GM Pro coil shock systems. This kit includes the roller-style steel thrust bearing, precision washers, and the specialized wrench tool needed for proper installation and adjustment on General Motors suspension platforms.

The thrust bearing assembly handles the lateral and compressive loads generated by coil-over suspension under acceleration, braking, and cornering. Steel roller bearings reduce friction at the shock mount point, allowing smooth suspension articulation while maintaining consistent ride height and dampening characteristics. The included wrench enables precise torque application during installation, critical for eliminating play that can degrade handling feel and increase NVH (noise, vibration, harshness) at the chassis mount. This kit is engineered specifically for QA1's Economy line, matching the load ratings and geometry of those shock bodies.

Street performance builders, autocross competitors, and off-road suspension technicians rely on bearing kits like this to maintain the integrity of aftermarket coil-over systems. Worn or missing thrust bearings cause clunking, uneven damping response, and accelerated shock wear. Replacement or upgrade-level bearing assemblies are essential maintenance items for any vehicle running coil-overs under repeated load cycles, especially those seeing track duty or aggressive street driving.

QA1 Economy shocks represent an accessible entry point into adjustable coil-over suspension for budget-conscious builders. This bearing kit ensures those shocks perform reliably by providing the precision wear components and tools needed for proper installation and future service intervals.
