Precision Remanufacturing Backed by Real Testing
At Turbo Kings, every Detroit Diesel DD15 air compressor that enters our facility is rebuilt to the highest standards of precision, quality, and testing — the same standards that define our reputation across the diesel and heavy-duty industry.
This compressor, designed for 2012–2022 Detroit Diesel DD15 engines found in Freightliner Cascadia and Western Star trucks, supplies the vital air pressure required for brakes, suspension systems, and emission controls.
Manufactured by Bendix, the BA-921 / BA-922 series air compressor is known for its two-cylinder, water-cooled design and long-term reliability under high-duty-cycle operation. At Turbo Kings, each unit is fully remanufactured, not just resealed, ensuring performance equal to or exceeding OEM specifications.
Every compressor is disassembled, media-cleaned, and inspected for piston scoring, bearing fatigue, and head flatness.
Internal components — including pistons, crankshafts, bearings, valves, and sealing hardware — are replaced with premium OEM-grade Bendix parts.
During the process, all air and water lines are ultrasonically cleaned to remove carbon, oil residue, and scale buildup, restoring unrestricted airflow and coolant circulation.
After reassembly, each compressor is tested on our in-house bench under 5 GPM and 2000 PSI simulated engine load, verifying pressure output, flow performance, oil control, and valve timing accuracy before shipping.
This isn’t outsourced or estimated — it’s physically tested right here at Turbo Kings.
