Hey guys, did a search but most of the posts are really old and with all the new stuff going on lately in regards to pulleys I wanted to lend an ear to what you all think is the best supercharger belt option for us right now? Gates? Dayco? Jaguar? Let's hear what you guys are running and if you could provide part numbers I would appreciate it, I am going to put a new one on as mine is almost 3 years old . Stock pulleys everywhere right now so keep that in mind when giving part numbers

No one has any input? Someone must have an opinion on this or at least a preference? I could use some feedback

try this thread...

DIY - Serpentine Belt Replacement

I agree, there are hundreds of threads about this, most say 'get a gates, or goodyear' but you rarely see part #'s...
take a lot of reading....

You have two belts on the 55K engine. If one fails at speed it will probably take out the other.

Replace both belts with OEM MB. Also replace the platic belt tensioners on each belt, they are cheap and inexpensive. They are a failure point. Put the old pulleys and belts in your trunk spares box in case you need an emergency repair. Spin all the other pulleys. If they make a squeaky noise replace them, lube them if not sealed and put in spares box. Before you replace the belts take a photo of the layout and look at the belt picture in your OM. it will make threading easier.

When you have both belts off It might be timely to change your supercharger oil! Search for these links.

Make sure you observe torque settings.

You runing a stock pulley or something bigger? See all the info you need here. Gates belts just add HD after the part number for the heavy duty belts,

Lots of good info in that thread!


I replaced my OEM supercharger belt with the recommendation for the 51" gates belt in that thread, and am happy. My car is all OEM under the hood.

Kleemann 168 uses the factory size so I use factory MB part.

Stock for now. Probably going to do something soon on some new tech that is becoming available

I have seen lots of people say this in my searches, would you mind elaborating mikey? What makes it better in your opinion? Also the part number I have for the Jag belt is NCC7740AD. Is that the number you've used?

Thanks for all the replies guys!

when i used to datalog and dyno a lot, it seemed to maintain boost without slippage better than the others. i can't remember part numbers but if you got that from a search here it should be correct.
