Designed with a focus on precision engineering, the GPM LMB192122 kit replaces stock components on the TEAM LOSI Micro-B 2WD Buggy with stiffer alloy front caster blocks, front spindles and rear hubs. The parts provide tighter bearing positions to reduce radial and axial play, resulting in smoother wheel rotation and improved chassis stability under load. These durable alloy pieces are intended for hobbyists seeking a robust, performance oriented upgrade path.
