Description

Shock Preload Adjusting Tools Pair – Professional Suspension Setup

Overview

This two-piece shock preload adjusting tool system is engineered for suspension technicians and motorcycle/automotive shops that require precision and safety when adjusting shock spring collar preload. The dual-tool design allows one technician to hold the collar stable while a second adjusts the preload without risk of slipping, rounding, or damaging expensive shock components.

Each tool features a semi-circular hook profile with a precision-machined engagement tooth that seats into adjustment notches on shock collars, ensuring positive grip and preventing cam-out. The flat steel handle with storage hole provides ergonomic control and workshop convenience. Both tools are finished in durable matte black coating for corrosion resistance.

Whether you're stocking tools for a full-service suspension shop or expanding your diagnostic capabilities, pair this system with complementary tools like suspension preload spanners for a complete adjustment solution.
