Precision Rebuilding Backed by Real Testing
At Turbo Kings, every TAS65166A Sheppard Power Steering Gearbox is rebuilt with the same precision, process control, and pressure testing that set our standards in the diesel and heavy-duty industry. Manufactured by Sheppard, the TAS65166A model is a widely used steering gear found in Freightliner, Kenworth, and Peterbilt trucks from 2005 through 2020, valued for its strength, smooth hydraulic performance, and long service life.
We don’t just replace worn parts — we restore, validate, and certify each gearbox to perform at or above OEM specifications. Every unit is fully disassembled, media-cleaned, and carefully inspected for wear, cracking, and housing fatigue. All internal seals, bearings, and shafts are replaced with Sheppard-grade OEM components, guaranteeing dependable steering response and leak-free operation.
After reassembly, each gearbox is bench-tested in-house at 5 GPM and 2000 PSI to verify hydraulic integrity, pressure balance, and zero leakage before leaving our facility.
This isn’t outsourced or guessed — it’s physically tested and verified right here at Turbo Kings.
