Diesel Fuel Injector Shims

Often overlooked, diesel injector shims are vital micro-components that ensure engine precision and power. Their correct selection and installation are fundamental to a successful injector overhaul.

Unmatched Benefits for Performance
The primary advantage lies in achieving exact calibration. These thin spacers allow technicians to set the precise injector needle lift and height, directly impacting fuel spray pattern, atomization, and timing. This calibration is crucial for restoring optimal engine power, fuel efficiency, and meeting strict emissions standards.

Engineered for Accuracy & Durability
Manufactured from high-grade spring steel or speciality alloys, shims undergo precise stamping and heat treatment. This process guarantees consistent thickness, exceptional flatness, and resistance to compression under extreme pressures and temperatures, ensuring long-term stability and reliable performance.

Advantages for the Workshop
Using organized, application-specific kits—like our 505pcs set for Bosch/Denso/Cummins—streamlines the repair process, reduces downtime, and eliminates guesswork. This leads to faster, more accurate repairs and guarantees that every rebuilt injector performs to its original specifications.
