I'm currently in search of genuine Cummins parts for our ongoing projects. We need to ensure the highest quality and reliability for our operations, so I'm particularly interested in sourcing components that meet or exceed OEM standards. If you have a catalog or list of available parts, please share it. Additionally, I'd like to know about any special pricing or bulk purchase options you may offer. Timely delivery is crucial for us, so info on lead times would also be appreciated. Looking forward to your prompt response!
