Cadillac CTS-V - Belt size

Anyone using SLP's 25% underdrive balancer for LS2? What size belt do you use? Thanks!

Nobody has replaced their balancer on an LS2? Mine is about to fall off and I would like to order an under drive but SLP and others don't list a belt size for CTS V. Any help would be much appreciated!

Do people just replace the balancer with another OE one? Underdrive not popular for some reason?

There are several different brands being used by forum members. Not sure about the UD amounts. 25% is a lot considering the electrical requirements of our cars. Search can be your friend.

Personally, I use the ATI 10% UD (#917278).

Did you ever find out the belt size? I'm getting ready to install the SLP pulley on my 05 V.

I too would like to know the belt size for the SLP UD belt. Are the LS6 and L62 the same? I have a 05 LS6 and need the belt size.

Thanks so much.
