I am trying to figure out which balancer I need so I can replace my old ones.

The stamp on the side of the balancer reads: 28 6 CW CMC 10

Any help would be appreciated.

Thanks!

Hi Sonny,

It looks like you have either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2860 spring strength option for your replacement balances. Thank you!

Hello. My balancers are Jordan 2830. The bottom shoe is 1 1/16. Which balancer should I get, the 351 or the 390?

Balances are not brand specific but if it is measuring over 1", I would recommend going with the S390 since it could have worn down a bit over time.
