What Delco Remy does

Delco Remy, founded in 1896 in Anderson, Indiana by Perry and Frank Remy, manufactures heavy-duty starters and alternators for commercial trucks, buses, and off-highway equipment. The portfolio spans 10 starter families (gear reduction 28MT through 150MT and straight drive 37MT through 50MT) and more than 15 alternator families (brush 20SI through 30SI; brushless 23SI through 55SI; plus transit-focused 50DN/50DN+), engineered around proprietary technologies including Integrated Over Crank Protection (IOCP), Smart Integrated Magnetic Switch (Smart IMS), Remote Sense voltage regulation, Electrical Soft-Start, brushless designs with 13 fewer moving parts, and the hairpin-stator 40SI high-output alternator. The brand also offers remanufactured starters and alternators with core-deposit economics, supported by digital tooling (e-catalog, Fuel Economy Calculator, Core Identification, free online technician training) and operator/marketing assets (Connect newsletter, Tech Tip videos, sponsorship of ~30 technician competitions annually).

The business operates as a brand under PHINIA Inc. (NYSE: PHIN), formed in 2023/2024 from BorgWarner's spin-off of its former Delphi and Remy businesses; the DELCO REMY mark is licensed from General Motors LLC to PHINIA Technologies Inc. Revenue is generated through hardware sales across OEM/OES channels (with 28SI as standard position on Freightliner and Western Star trucks and Navistar IC Bus), independent aftermarket distributor networks (four in Australia, one in New Zealand, plus Americas and EMEA coverage), regional sales and service manager-led fleet relationships, and ancillary technical-support/training services. Pricing is quote-based and not publicly disclosed. Operations include manufacturing in Mexico and historical manufacturing in Anderson, Indiana, distribution in Laredo, Texas and Melbourne, Australia, with a stated target of 95%+ fill rate in Oceania. The company reports 51-100 employees at the brand level and serves customers including Ruan Transportation, Navistar (SuperTruck), Freightliner/Western Star, Navistar IC Bus, and long-haul owner-operators.
