Description

39mm Fork Seal Driver

Brief Overview

This 39mm fork seal driver is a purpose-built tool for installing and servicing fork seals on motorcycles, ATVs, and similar suspension systems. The split-sleeve construction with hinged pin joints allows the driver to slip over the fork tube without disassembly, making seal installation faster and more efficient in the shop. Whether you're stocking smaller diameter seal installation tools or building a complete fork service kit, this 39mm driver is an essential addition to any professional suspension department.

Key Features

  • Split-Sleeve Design: Two-piece hinged construction allows the driver to separate and fit over fork tubes without removing the stanchion
  • Hinged Pin Joints: Precision-machined dovetail hinges hold both halves securely aligned during operation
  • Knurled Outer Surface: Dense knurling provides superior grip control, even with light machine oil or wet hands
  • Gold/Zinc-Plated Finish: Durable plating resists corrosion and extends tool life across multiple service cycles
  • Chamfered Bore Edges: Smooth, beveled end edges protect fork seals from damage during installation
  • Precision 39mm Bore: Engineered to exact specifications for consistent, centered seal seating

Business Advantages

This tool closes a critical gap in suspension service offerings. Resellers benefit from stocking a dedicated 39mm driver because:

  • High-Frequency Application: 39mm forks are common across mid-range and sport motorcycle platforms, ensuring steady demand
  • Repeat Orders: Shops that service suspension rebuild multiple seals per week, driving consistent inventory turnover
  • Margin-Friendly: Precision hand tools carry healthy wholesale margins with minimal inventory carrying costs
  • Bundling Opportunity: Pair with larger bore seal drivers to create complete fork service kits that appeal to professional shops
