This sale is for an individual pulley to fit a Cadillac STS-V, CTS-V, XLR-V, or LSA Supercharger Modular Pulley System (MPS). These are made on programmable equipment and I've sold over 2500 systems and I've heard nothing but compliments. I've also been running one on my car for nearly 80,000 miles with no issues, check my response!
If you have any questions please contact me via or call at
This is for only a pulley, no hub for customers that have already installed one of my modular systems. The pulley size you'd like is up to you but pulleys smaller than 2.55" will require the supercharger snout to be machined. A good rule of thumb is that for each 0.1" drop in pulley size you can expect to gain 1 pound of boost. This being said upgrading your 2.8" pulley to one of these great looking 2.55" pulleys should net you 2.5 - 3 pounds off increased boost.
If you would like to use a pulley smaller than 2.55" or if you think that you maywant to in the future I can machine your snout down and if you order a pulley system as well I will install it for you so you won't need to buy a puller / install tool or take it to a shop.What you'll need to do is remove the snout and send it to me or you can come by my shop inSt. Paul, Minnesota. Please feel free to contact meif you have any questions. These pulleys look and perform great! They make swapping a pulley when you're going to the track or running high octane fuel a snap, then just swap back to a larger pulley when you want to do normal every day driving.
Domestic shipping will be free for items bought through my store!
I can make ANY size (2.3-3.8 and any size in between) you would like, just email me after winning the sale to let me know what size you want
If you'd like insurance, I'll add that for just $4.50 for 1 pulley, 8.00 for 2 pulleys, and 11.00 for 3 pulleys. Let me know in the same email that includes the size you'd like.
The pulleys are machined from billet aluminum for both strength and light weight. The pulleys are available in two finishes. These are Polished (add 5.00) and Machined.
This is a great mod for your supercharged STS-V, CTS-V, or XLR-V to make MORE POWER!!!
Feel free to email me with any questions or would like to order an extra pulley right away (one for the track and another for normal driving)!
