Alternators
Import and domestic. Light passenger to heavy commercial. Built to OEM spec or improved on the regulator and bearing where the field data says we should.
OEM Supplier · Since 1972
Manufactured
OEM-grade alternators and starters, rebuilt to outlast the original. Engineered in Oklahoma City for the manufacturers who ship at scale.

A used core enters our floor. It leaves better than new.

Stage 01
Core In
A used unit returns from the field. Catalogued, weighed, photographed against its OEM application.
Stage 02
Strip & Diagnose
Full teardown. Every winding, bearing, rectifier, and brush is logged against its failure mode.
Stage 03
Improve
Reverse-engineered where the OEM design fell short. Better bearings, better diodes, tighter tolerances.
Stage 04
Process Test
Loaded on the test stand. Every unit runs the full RPM curve before it ships - no exceptions.
Made on this floorBuilt where it was built.
Built where it was built.
Tested before it ships.
Every unit is broken down to its components, evaluated against the failure mode that brought it in, rebuilt with parts your platform actually needs, and load-tested on the same bench before it leaves Oklahoma City.

Why OEMs choose PPROKSized for OEM programs.
Sized for OEM programs.
Engineered like one of yours.
Most reman shops sell to the aftermarket. We sell to the people who put the alternator on the truck the first time. The positioning is intentional - and it changes how we build, test, and ship every unit.
01
Built for an application, not a catalog.
We reverse-engineer where the OEM design fell short - tighter bearing tolerances, better diodes, regulators selected for the actual load profile your platform sees in the field. The result is a unit that outlasts the one it replaces.
02
Every unit on the test stand. Every time.
Process testing on the full RPM curve before any unit ships. No statistical sampling, no batch-pass philosophy. If it leaves Oklahoma City, it has produced rated output under load.
03
Stable, US-made, scaled for OEM volume.
Fifty-three years in remanufacturing. A hundred-plus people on the floor in Oklahoma City. BBB A+. The supplier you can plan a multi-year program around.
The Green Initiative · APRA verified
Remanufacturing is the cleaner half of manufacturing.
A reman alternator runs at a fraction of the energy cost of a new one, costs your distributors less, and keeps a few pounds of copper and aluminum out of the resmelting cycle. We have been doing this since 1972.

Tons CO2 saved by the reman industry every year
- Energy
Recovered units stay out of the smelter, conserving the energy required to refine raw aluminum and copper at scale.
- Material
Iron, aluminum, and copper from existing cores are re-used in place rather than dug from a new pit.
- Landfill
Core-charge economics keep tons of recoverable mass out of US landfills every year.
- Air
Avoiding the resmelt step removes a meaningful slice of the pollution profile attached to each unit.
- Performance
Reman units routinely match or exceed the durability of new - measurably so, on the same test stand.

See the full sustainability briefWhat we make
A focused line, engineered around three things.
Starters
Direct drive and gear reduction. Rebuilt with new solenoids, contacts, and brushes; load-tested before it leaves the floor.
Components
Stators, rotors, rectifiers, regulators, brushes, bearings. The same parts we use - available as service components for partner rebuilders.
