Description

49/50mm Combo Fork Seal Drivers

Brief Overview

This two-piece combo fork seal driver is engineered for motorcycle and ATV suspension technicians who need a single tool for both 49mm and 50mm fork seal installations. The split-clamp hinge design allows the driver to open around the fork leg, eliminating the need for multiple tools and reducing installation time. Pair this with smaller diameter seal drivers to build a complete fork seal kit for your shop.

Key Features

  • Split-Clamp Construction: Two-piece hinged halves allow tool to clamp securely around fork leg without disassembly—faster installation, reduced risk of seal damage
  • Dual-Size Compatibility: Single tool handles both 49mm and 50mm fork seal applications, minimizing inventory requirements
  • Diamond Knurled Grip: Textured knurling across the body ensures secure hand purchase, critical for controlled seal press-in
  • Smooth Cylindrical Bore: Precision-machined inner surface contacts and drives seal squarely into fork tube
  • Yellow Zinc Plated Finish: Corrosion-resistant coating withstands shop humidity and cleaners
  • Chamfered Opening: Slightly beveled outer edge guides seal into bore and reduces binding risk during installation

Why Resellers Choose This Tool

Operational Efficiency: The combo design eliminates the need to stock separate 49mm and 50mm drivers—one SKU covers both applications. This reduces shelf space and simplifies picking for technician orders.

Lower Total Cost of Ownership: Techs can service more fork seal jobs with fewer tools in their kit, improving profitability per service call.

Reduced Damage Risk: The hinged clamp-on design prevents accidental tool contact with seal lip during installation, lowering comebacks and warranty claims.

Inventory Flexibility: Stock one combo driver instead of two single-size tools, freeing capital for higher-margin inventory while maintaining full application coverage.
