Repl 90000 Thrust Washer Set

The Allstar Performance ALL 90007 Repl 90000 Thrust Washer Set is a precision steel component engineered for timing gear drive assemblies. This thrust washer kit maintains proper end-play clearance and axial preload in high-RPM engine timing systems, preventing excessive gear movement and extending drivetrain longevity. The set delivers the critical bearing support needed in competition engines, street performance builds, and racing applications where timing gear reliability is non-negotiable.

Steel construction provides the durability and hardness required to handle repeated shock loads in high-horsepower configurations. The tight tolerances of this Allstar timing gear thrust washer kit ensure consistent spacing between gears and the block, minimizing lateral deflection that could cause gear tooth damage or chain/belt misalignment. Proper thrust washer selection is essential—undersized or worn washers allow excessive gear float, which accelerates wear on timing components and can lead to catastrophic failure at peak engine loads.

This washer set is intended for engine builders, performance shops, and serious enthusiasts rebuilding or refreshing timing gear drives on small-block and big-block platforms. Whether you're restoring an original engine, upgrading to higher-performance gearing, or replacing worn components after a complete teardown, this Allstar kit ensures your timing system maintains factory-correct clearances. The compact, lightweight package (0.21 lbs) makes it easy to keep on hand during any engine assembly or rebuild project. Part number ALL90007 fits within the broader Allstar Performance ecosystem of engine components trusted for consistent performance across street and track applications.
