Explanation of options:

Turbocharger Size references the size of your compressor wheel, for example the cast 62mm means your turbo will have a cast 62mm compressor wheel. The cast 62mm compressor wheel will spool very similar to the stock turbocharger, and will make up to about 500 hp. Whereas the Billet 69mm SXE will have a Billet 69mm compressor wheel, having a larger compressor wheel with allow the truck to make more horse power! But you will sacrifice some low end response.

Most customers find that they like the 62-66mm sizes because they enjoy the faster spool up and power! 


Cast vs. Billet explanation:

The term cast wheel is referencing the material used to produce the compressor wheel. Our cast wheels are made of cast aluminum and they are a 7 blade design, this style wheel has been around for many many years and is very reliable. Cast wheel are the most cost effective wheel option we offer.

Billet wheel means that the compressor wheel is made from a solid block of aluminum that is CNC machined to our exact specification. Billet wheels are much more advanced wheels compared to there cast wheel counterparts because we can use a stronger material, more aggressive blade designs, and make them lighter weight then a cast wheel. Billet wheels will provide faster spool up and make more horse power then a cast wheel will. Most of our billet wheel utilize a 6 blade design!


Thrust bearing explanation:

We offer three different thrust bearings: Standard, Heavy Duty and Steel 360* bearing. 

Our standard bearing is very robust and extremely reliable when used with in its design limits, but In our high performance industry many of our customers like to push the limits so we decided to offer bearings that would help them push those limits!

Our next step up from a standard bearing is the Heavy Duty bearing, this bearing is great for guys that are heavy haulers and beat on these trucks every day. The Heavy Duty bearing uses a custom cut bearing to allow the bearing to handle more abuse.

Finally we have the big dog of thrust bearings, our Steel 360* thrust bearing is the strongest bearing option we offer. This bearing has 360* of coverage and has a very aggressive pitch on the oiling surface allowing our turbos to be used in very extreme duty applications. We recommend this bearing on trucks being used in racing applications.
