The Lainer Suspension compression adjuster and piston holder wrench is a dual-purpose workshop tool for Showa and KYB cartridge fork systems. It’s intended to help with compression-side service work by providing proper engagement during disassembly and reassembly. Use it when you need secure control of internal fork components to reduce the risk of damage during servicing.

Built For Real-World Suspension

This tool is suited to routine fork rebuild work where access to the compression piston holder or cartridge lock nut is required. It’s designed to support accurate, repeatable handling of parts that can be difficult to hold or loosen with general-purpose tools.

Inside the System

• For Showa closed cartridge forks: used to dismount the compression piston holder and can be useful to dismount the free piston during a rebuild or when changing it.
• For KYB cartridges: used to dismount and mount the lock nut, which can loosen.
