Is Your S300 or S400 Turbo Losing Its Boost? We Can Rebuild It!

by Cecilia Herrell 10 Jun 2026

As a diesel owner, you know that keeping your rig running at peak performance isn’t just a want, it’s a need. Whether it's your daily driver, dedicated work truck, heavy hauler, or a weekend sled puller, you expect your engine to deliver power whenever you need it.

Unfortunately, over time, even the toughest turbos slowly wear down.

If you’ve noticed your truck lagging when you hit the throttle, maybe you’ve even heard odd noises from under the hood, or spotted some oil leaks near your turbo, well it’s actually trying to tell you something.

Before you start playing the guessing game and stressing about the cost of a brand new turbo, we have some good news… You may not actually need a new turbo. At Stainless Diesel, we created a new cost effective solution for you and your turbo! 

Don't Replace It, Rebuild It

At Stainless Diesel, we offer premium S300 & S400 Turbo Rebuild Services designed to bring your turbo back to life. We restore your turbo's reliability and power while saving you money, giving you the best of both worlds without sacrificing performance.

Why rebuild? It breathes new life into your existing setup for just a fraction of the cost of a brand new turbo, meaning you get back on the road (or back on the track) with money left in your pocket.

What’s Included in a Stainless Diesel Turbo Rebuild Service?

We don’t just slap on some new parts and call it a day. Our meticulous rebuild process ensures your turbo meets the highest standards of durability and performance:

  • Complete Teardown & Inspection: We completely disassemble your turbo to inspect every single component for microscopic wear, cracks, or structural damage.

  • Professional Cleaning: A thorough, deep clean of all reusable parts to eliminate carbon buildup and debris.

  • Premium Component Replacement: We replace worn internals with high quality, heavy duty bearings, seals, and thrust collars built to handle intense heat and pressure.

  • Precision Balancing: This is the secret to longevity. We high speed balance the entire assembly to ensure smooth, flawless operation under heavy boost.

Restore the Power You Expect

You purchased a high performance turbo for a reason. Don't let old, worn out bearings or leaking seals rob you of the boost you paid for. Let our team of skilled experts restore the reliability, efficiency, and aggressive power you expect from your turbo.
