About D&J Precision Machine
D&J Precision Machine is a well-known name in the diesel performance industry. The business was started in 2009 and is based in Ohio, where it concentrates on high-performance diesel engines and the components that go into them, serving street-driven vehicles as well as serious racing programs.
The range covers remanufactured Cummins engines and precision-machined parts such as cylinder heads and intake manifolds. Buyers can also order custom engine builds worked out around their own requirements, and ready-run engine packages are offered for those who want to keep installation time and downtime to a minimum. Active-duty military members and veterans can contact the company directly about a military discount.
Machining takes place in a modern facility that relies on advanced CNC techniques, with the aim of combining durability with strong output across the product line. Returns are accepted within 60 days, and refunds are issued in 10-14 days. Diesel performance parts in general are bought by drivers who want more power and reliability from a diesel engine, whether for towing, competition or off-road use.
