This precision-machined aluminum bearing collar set is engineered to optimize the performance and durability of the rear hub carriers on compatible Kyosho 1/8th scale racing buggies. Designed as a direct upgrade or replacement, these collars provide a secure and precise seating for the bearings within the rear uprights, minimizing unwanted play and extending bearing life under the rigorous demands of competitive off-road racing. Crafted from high-grade aluminum, they significantly enhance the structural integrity and stability of the rear suspension, translating to more consistent handling and improved power delivery on the track.
