Why OEM Matters
Genuine Parts. Not Imitation.
The aftermarket is flooded with parts that look right but aren’t. Counterfeit filters, substandard injectors, and off-spec seals may save money at the counter, but they routinely cause failures that cost far more to repair than the original price difference.
As an authorized dealer, Western Branch Diesel sources directly through Perkins’ distribution network. Every part we supply is traceable, validated, and built to the specification your engine requires. No guesswork about fit, compatibility, or material quality.
