GTM Twin Supercharger Kit replacement belts
 

A customer has the kit on his car and the belts shredded along with the idlers locking up. I've scoured the google looking for the belt part numbers. Contacted multiple vendors with no luck. If anyone has a list of belts and idlers I'd be super thankful.

He once had the twin SC from GTM but sold the car, he might have a record of what belts are needed.

Perhaps R/T Tuning can help you - they have a stage 2 SC kit in stock

Vivid is not selling GTM parts anymore, the website is outdated.

Thanks for the help guys. I’ve already hit up vivid. They were no help. Obviously Gamma is useless. I’ll message firehawk. Thanks

Messaged Firehawk, haven't heard back yet. In the mean time if anyone else has info that'd be great

My tuner just finished to install my Twin SC.
What is your pulley size ?

I have these numbers if you need anything let me know.. Here are the belts used for the twin super chargers.
92mm PULLEY
GTM-71-07-2120 main belt 7PK2120
GTM-71-07-0825 Left SC Belt 7PK0825
GTM-71-07-1030 Right SC Belt 7PK1030


88mm PULLEY

Main belt remains the same.
7PK810 Left Belt
7PK1025 Right Belt

This should help you out.

Thanks guys, we just had a supercharger lock up on it now. Need to send them out for rebuild.

All gtm idlers are OEM subaru idler belt pulleys. i just replace both my idlers on my GTM stage 1.5 kit. i did have to remove the gtm spacer for a smaller washer to make it fit right.
