Common Rail Injector Adjusting Shim Kit for Bosch Denso G4

This Common Rail Injector Adjusting Shim Kit is an essential toolkit for professional diesel workshops and remanufacturing centers. It is specifically curated to service a wide range of injectors, including standard Bosch series and the advanced Denso G4 (Generation 4) systems.

In modern diesel engines, even a micron-level deviation in internal clearances can lead to poor performance. Our shims are manufactured with high-grade hardened steel to strict tolerances (often within 0.001mm - 0.002mm accuracy). They are used to calibrate critical parameters such as armature stroke, buffer stroke, nozzle needle lift, and solenoid air gap. Whether you are rebuilding an injector for a heavy-duty truck or a passenger vehicle, this kit provides the precise thickness variety needed to restore the injector to OEM specifications. The shims are resistant to deformation under high pressure, ensuring long-term stability of the fuel injection quantity.

• Micron-Level Precision: Manufactured to extremely tight tolerances to ensure accurate calibration of injector internal gaps.

• Wide Compatibility: Suitable for adjusting multiple gap types (armature, nozzle, solenoid) in Bosch and Denso G4 injectors.

• Durability: Made from wear-resistant, heat-treated steel that maintains its thickness even under extreme hydraulic pressure.

• Comprehensive Range: Available in various thickness steps (e.g., 0.01mm or 0.02mm increments) to meet any wear compensation requirement.

• Organized Storage: (Optional, if applicable) Comes in a labeled organizer box for quick identification and selection during repair work.
