Speedmaster 35 Spline Large Bearing Axle Brake Backspacing Sleeve 30mm PCE679.1002

The Speedmaster 35 Spline Large Bearing Axle Brake Backspacing Sleeve is a precision-engineered component designed for high-performance automotive brake and axle assemblies. This backspacing sleeve accommodates large bearing configurations on 35-spline axles, ensuring proper fitment and alignment in brake hub assemblies. The 30mm (1.183 inch) dimension is critical for correct spacing and load distribution across the bearing races and brake rotor interface.

Built to OEM specifications, this sleeve provides reliable performance in both street and racing applications where precise axle geometry is essential. It is commonly used in custom and high-performance brake system builds, rear-end modifications, and trailer brake installations where large-diameter bearings and brake components require exact backspacing. The component integrates seamlessly with standard 35-spline axle shafts and works alongside large bearing cartridges to maintain brake efficiency and safety.
