Sir Tools

About Sir Tools

For professional technicians who refuse to compromise, Sir Tools has been the name behind some of the most precise and reliable special service tools in the automotive industry. Founded by John Sir, the brand grew out of a firsthand recognition of a real-world problem: quality specialty tools for European vehicles — particularly German makes like Porsche, BMW, Mercedes-Benz, and Volkswagen — were simply not easy to source in the United States. Rather than work around the gap, Sir set about designing and manufacturing the tools himself, and a legacy was born.

Based in Paradise, California, Sir Tools has spent over three decades refining its craft. Disc brake caliper piston tools, wheel bearing and hub assembly tools, seal installation kits, and flywheel locks are among the specialty items that have made Sir Tools a trusted fixture in professional bays across the country. The brand also offers practical everyday workshop items like screwdriver sets engineered to the same uncompromising standard.

A Philosophy Built on Quality

What sets Sir Tools apart is a straightforward but demanding manufacturing philosophy: never cut corners to reduce cost. Every tool that leaves the Sir Tools facility is built to meet the exacting tolerances that foreign vehicle repair demands. This commitment has earned the brand OEM manufacturing contracts — meaning some of the most widely recognized automotive special service tools on the market are actually produced by Sir Tools under private label agreements for other companies and manufacturers.

Specialty Tools for Foreign and Domestic Vehicles

While Sir Tools made its name in the European vehicle space — with dedicated tooling for Porsche, BMW, Mercedes-Benz, Volkswagen, Volvo, and air-cooled platforms — the brand's catalog extends to domestic and Asian vehicle applications as well. From engine timing and camshaft tools to brake service equipment and suspension components, Sir Tools covers a wide range of professional service needs.

Whether you are rebuilding a vintage German sports car or performing a routine brake service on a modern domestic vehicle, Sir Tools provides the purpose-built instruments that make the job cleaner, safer, and more accurate. The brand's catalog spans automotive specialty tools, hand tools, and shop equipment — all developed with the professional technician in mind.
