Precision Rebuilding Backed by Real Testing
At Turbo Kings, every HD94 PAB Sheppard Power Steering Gearbox is rebuilt to the same precision and in-house testing standards that define our reputation across the diesel and heavy-duty steering industry. Manufactured by Sheppard, the HD94 line represents a lighter-weight yet high-performance steering system designed for modern highway and line-haul trucks — commonly found in Peterbilt 579 and Kenworth T680 (2015–2016) models.
We don’t just 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 for cracks, wear, or fatigue. Internal seals, bearings, and shafts are replaced using premium Sheppard-grade components that meet strict original specifications.
After precision assembly, every gearbox is bench-tested in-house at 5 GPM and 2000 PSI, verifying hydraulic integrity, internal pressure balance, and zero leakage before it leaves our facility.
This isn’t outsourced or assumed — it’s physically tested right here at Turbo Kings.
