Precision Engineering Built from the Ground Up
The Turbo Kings R955300 Air Dryer is a brand-new precision-engineered replacement for the Bendix AD-9 units installed across Volvo and Mack heavy-duty platforms. Unlike re-cores or aftermarket clones, this model is designed and manufactured entirely by Turbo Kings—engineered for OEM-grade fitment and superior performance under demanding freight-duty conditions.
Every casting, seal, and circuit port is machined from new aluminum billet and aligned to OEM geometry, ensuring seamless installation with Volvo D11, D13, and Mack MP7/MP8 air-management systems. The result is a dryer that performs flawlessly, purging moisture consistently and protecting the entire brake network from corrosion and freeze-related failures.
Advanced Air Management and Component Design
Built with a high-efficiency desiccant core and robust purge assembly, the Turbo Kings R955300 guarantees consistent air purity and system reliability. Its heater circuit is optimized for cold-start duty cycles, while the internal flow path is re-channeled for higher throughput and lower restriction.
New Cast Aluminum Housing: Lightweight yet corrosion-resistant, CNC-milled sealing surfaces for perfect fit.
High-Capacity Desiccant Cartridge: Factory-packed and pre-dried for maximum moisture absorption.
Upgraded Purge Valve Module: Engineered to maintain steady purge pressure and fast recovery cycles.
12 V Heater Element: Pre-tested for resistance stability and rapid anti-freeze protection.
Premium Check and Relief Valves: Balanced to sustain 120–150 PSI operating pressure under full load.
Each unit is pressure-tested and electrically verified prior to packaging, guaranteeing leak-free performance from the first installation.
What Makes a Turbo Kings Air Dryer Different
Turbo Kings’ new-build dryers are more than simple replacements—they’re engineered upgrades. By producing housings and valve assemblies in-house, Turbo Kings eliminates casting porosity, thread fatigue, and flow imbalance common in remanufactured cores.
This manufacturing precision delivers:
Faster Reservoir Recovery: Reduced compressor cycling and improved air balance.
Cleaner System Operation: Prevents moisture-induced corrosion in valves and brake chambers.
Simplified Maintenance: Direct-fit service cartridges and purge components.
Consistent Purge Performance: Eliminates “wet tank” symptoms common in aging AD-9 designs.
For fleets operating in mixed climates, this dryer provides unmatched reliability through both cold-start and high-load environments.
