Description

38mm Fork Seal Driver – Professional Fork Suspension Tool

Overview

This 38mm fork seal driver is purpose-built for motorcycle and ATV suspension work, delivering the precision alignment needed to install fork seals without damaging the delicate rubber lip or scratching the fork tube. The split-hinged design allows the driver to clamp securely around the fork without requiring disassembly, saving labor time and reducing the risk of seal misalignment. If you service multiple fork sizes, our range includes 37mm and 39mm drivers to cover the most common suspension specifications.

Key Features

  • Diamond Knurled Grip: Textured outer surface provides secure hand control during vertical driving pressure
  • Yellow Zinc Plating: Durable corrosion-resistant finish suitable for wet workshop environments
  • Compact, Lightweight Design: Easily stored in tool kits and works alongside standard press equipment
