Description

50mm Fork Cap Wrench with 3/8-Inch Square Drive

Brief Overview

This 50mm fork cap wrench is purpose-built for SHOWA front fork service and maintenance. The tool features a large C-shaped 50mm opening designed to grip fork caps securely, while the integrated 3/8-inch square hole accepts standard torque wrenches and breaker bars for precise fastener control. The opposing end incorporates a narrow two-prong fork design that functions as a piston rod holder, making this a genuinely dual-purpose tool that simplifies cartridge removal during front fork overhauls. Mechanics working with SHOWA suspension systems will find this wrench essential—complement it with 48mm fork seal installation tools or explore 49mm fork cap wrenches for complete size coverage across suspension platforms.

Key Features

  • 50mm C-shaped fork cap opening with dual inward-facing prongs and flat contact surface for positive engagement
  • 3/8-inch square drive hole positioned at tool center for torque wrench attachment and accurate fastener tightening
  • Dual-function design: Large end removes/installs fork caps; narrow prong end secures piston rod during cartridge extraction
  • Black powder-coated metal construction resists corrosion and provides durability in shop and field environments
  • Single-piece stamped/machined steel body eliminates joint failures and ensures consistent tool performance
  • Flat handle design distributes force evenly and prevents tool rotation during use
