Sinister Diesel » Alliant Power

We aggressively serve the out-of-warranty customer by providing high quality products in the field. We help keep Original Equipment Manufacturer (OEM) product as the preferred service part so vehicles and equipment continue to perform like new and provide end users with greater ownership satisfaction.

Service customers prefer OEM parts because they want “first time fit.” Every shop’s repair efficiency depends on ease of installation. So they appreciate parts built to OEM specifications and testing. They also like our Limited Warranty Policy.

It takes engineering, production control and quality assurance working together to provide reliable fit and function 100% of the time. Ensuring that original equipment sales extend into the post warranty period results in greater customer satisfaction and the likelihood of that vehicle or piece of equipment being purchased again.
