Precision Rebuilding Backed by Real Testing

At Turbo Kings, every M100 PRZ Sheppard Power Steering Gearbox that enters our facility is rebuilt with the same precision, process control, and verification that define our name across the diesel and heavy-duty industry. Manufactured by Sheppard (M-Series), this gearbox is a proven design in Peterbilt and Kenworth applications (2005 – 2018), delivering dependable steering response under demanding fleet conditions.

We don’t just replace worn components — we restore, validate, and certify each gearbox to meet or exceed OEM standards. Each unit is fully disassembled, media-cleaned, and carefully inspected for wear or fatigue. All internal seals, bearings, valves, and shafts are replaced with premium Sheppard-grade parts before precision reassembly.

After assembly, every gearbox is bench-tested in-house at 5 GPM and 2000 PSI, verifying hydraulic integrity, internal pressure balance, and leak-free performance before it ever leaves our facility.

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