Precision Rebuilding Backed by Real Testing
At Turbo Kings, every TAS65155A Sheppard Power Steering Gearbox is rebuilt under the same controlled process and rigorous testing standards that define our brand. Manufactured by Sheppard, the TAS65155A is one of the most trusted steering gearboxes found in Freightliner, Kenworth, and Peterbilt applications from 2005 through 2020, known for its exceptional reliability and consistent steering performance across demanding fleet and long-haul operations.
We don’t just replace worn parts — we restore, validate, and certify each gearbox to meet or exceed OEM specifications. Each unit is completely disassembled, media-cleaned, and thoroughly inspected for housing fatigue, shaft wear, and internal damage. All seals, bearings, and valves are replaced using Sheppard-grade OEM components, ensuring precise steering control and extended service life.
After reassembly, every gearbox is bench-tested in-house at 5 GPM and 2000 PSI, confirming pressure stability, hydraulic integrity, and leak-free operation before leaving our facility.
This isn’t outsourced or assumed — it’s physically tested and verified right here at Turbo Kings.
