Description
Our LB7 64mm drop in stock appearing turbo is a brand new unit. Many upgrades were done to these units. With the restriction of the exhaust housing the LB7s have, we utilize a high flowing exhaust housing – an RDS exclusive feature. The increased A/R of the exhaust housing has proved to flow more and lower EGTs.

- 64mm 10 blade high flow turbine
- Adjustable wastegate
- Proper modifications this turbo can support 650hp

Frequently Asked Questions – LB7 64mm Complete Turbocharger (2001-2004)
What vehicles does this 64mm turbo fit?
This complete 64mm turbocharger fits 2001-2004 Chevrolet Silverado and GMC Sierra HD 2500/3500 trucks with LB7 Duramax diesel engines. It’s a direct drop-in replacement using all factory mounting points with no modifications required.
What makes the RDS LB7 turbo different from other 64mm turbos?
The exclusive RDS feature is the high-flow exhaust housing designed specifically for the LB7. The factory LB7 exhaust housing is very restrictive. Our increased A/R exhaust housing has proven to flow significantly better and lower exhaust gas temperatures (EGTs) compared to factory and other aftermarket options.
How much power can this 64mm turbo support?
With proper modifications, this 64mm turbo can support up to 650 horsepower. It’s designed for trucks with upgraded fuel systems and delivers excellent performance for daily driving, towing, and performance applications.
What is the adjustable wastegate feature?
This turbo includes an adjustable wastegate actuator that allows you to fine-tune boost control. You can adjust when the wastegate opens to control maximum boost pressure, providing flexibility for different tuning levels and performance goals.
Do I need a federal downpipe for this turbo?
Yes, this turbo requires a federal-style downpipe for proper fitment. It will not work with California emission-style downpipes due to the different exhaust housing design. The federal downpipe provides the proper connection point for the high-flow exhaust housing.
Do I need tuning to run this turbo?
Yes, custom tuning is required to properly utilize this 64mm turbo’s increased airflow capacity. The larger compressor, turbine, and high-flow exhaust housing require tuning adjustments to optimize air-fuel ratios, boost levels, and performance delivery.
What are the key technical specifications?
This turbo features a 64mm proprietary compressor wheel, 64mm 10-blade high-flow turbine, RDS exclusive high-flow exhaust housing with increased A/R, adjustable wastegate actuator for boost control, and all necessary hardware for installation.
How does the high-flow exhaust housing improve performance?
The increased A/R (Area/Radius ratio) of our high-flow exhaust housing reduces backpressure, allowing exhaust gases to exit more efficiently. This results in lower EGTs (exhaust gas temperatures), faster spool-up, improved turbo efficiency, and better overall performance compared to the restrictive factory housing.
What comes in the optional turbo install kit?
The optional turbo install kit ($75) includes all gaskets needed for installation: both up-pipe gaskets (at exhaust manifolds and exhaust housing), both drain gaskets, oil feed banjo, and both coolant banjos. These are essential sealing components for proper turbo installation.
What warranty comes with this turbo?
This complete turbocharger includes a 2-year warranty against manufacturer defects, providing comprehensive coverage for your performance upgrade investment.
Is there a core charge for this turbo?
No core charge required. This is sold as a brand new complete unit outright – you don’t need to return your old turbo, making this a straightforward purchase.
Is this turbo good for daily driving and towing?
Yes. Customer reviews specifically mention this turbo provides all the power needed for towing while maintaining smooth operation throughout the entire RPM range. It’s designed to deliver excellent performance for daily driving, towing, and spirited driving while supporting higher horsepower goals with proper modifications.

Just received my turbo in the mail. Upon opening the box there was no damage nor were there any components missing. Overall, it looks like a well-built unit. I really like the adjustable waste-gate actuator. My turbo did come with Ryan’s first-gen turbo instructions which threw me off for a sec but Ryan was very quick to respond to my email and clarify my confusion. Looking forward to being a future customer. I will update this review once I have the truck back on the street.

So far so good. Zero complaints. I’ve been looking for a replacement turbo where the original stock turbo on my 02 has almost 300k miles on it; it was time for a new one. After watching a few youtube videos I decided to go with the RDS. The truck seems to run alot smoother under load as well as through out the entire rmp range. I would highly recommend any RDS turbo.
