These high-precision clamping wheel hubs are engineered from durable aluminum, offering a robust and secure method for attaching wheels to the rear axles of 1/10th scale 2WD racing buggies, specifically the Kyosho Ultima RB7 series. Unlike traditional pin-style hexes, their sophisticated clamping design ensures a consistently tight fit, significantly reducing wheel slop and preventing wheels from coming loose during intense racing or competitive events. Finished in an attractive gunmetal, these 7.5mm offset hubs not only provide enhanced stability and improved power transfer to the wheels but also add a touch of factory aesthetics and premium durability to your vehicle's driveline.
