Precision Rebuilding Backed by Real Testing

At Turbo Kings, every THP600211 TRW Power Steering Gearbox that enters our facility is treated with the same precision, care, and process control that define our reputation across the diesel and heavy-duty industry. Manufactured by TRW, this gearbox is engineered for Freightliner Cascadia and Western Star (2014–2023) applications, delivering the steering performance, torque response, and reliability that fleets depend on.

We don’t simply replace worn components — we restore, validate, and certify each gearbox to perform at or above OEM standards. Every unit is completely disassembled, media-cleaned, and inspected. All critical wear items — seals, bearings, valves, and shafts — are replaced with premium-grade TRW-spec components.

After reassembly, each gearbox is bench-tested in-house at 5 GPM and 2000 PSI, verifying hydraulic integrity, internal pressure stability, and leak-free operation before it ever leaves our facility.

This isn’t outsourced or guessed — it’s physically tested right here at Turbo Kings.

What Makes a Turbo Kings Rebuild Different

In-House Pressure Certification – Every TRW gearbox is verified on a closed-loop test bench at 2000 PSI to ensure zero internal or external leaks.
Pre-Lubricated & Ready to Install – Each unit leaves our shop filled with fresh lubricant and sealed for immediate installation.
Precision Machining – Housing surfaces are resurfaced to strict tolerances to ensure proper alignment and torque distribution.
OEM-Level Components – Only genuine TRW-grade seals, bearings, and shafts are used — never cheap aftermarket substitutions.
Hands-On Expertise – Each rebuild is personally completed and signed off by a certified technician with years of diesel steering experience.
Warranty Confidence – Backed by a 12-month, unlimited-mileage warranty, because we trust our process and our craftsmanship.
