The Speedmaster PCE206.1025 is a precision-engineered preload spacer adaptor shim designed to adapt a large pinion to a small pinion support configuration. Built to work with oversize pinion support housings, this shim ensures proper preload settings during differential rebuilds and gear setups, helping deliver accurate bearing preload and long-term drivetrain reliability.
Ideal for performance differential assembly and gear installation, this adaptor shim simplifies the transition between mismatched pinion and support sizes, reducing the need for custom machining. A must-have component when building or rebuilding rear ends equipped with oversize pinion support housings, keeping your differential assembly precise and properly loaded.
