I'm looking at the Teraflex 2.5" BB and not sure what the difference is between the "no shock" products - one being with adapters and the other without adapters. Can someone help out?

 

You generally want your shocks to be long enough to compensate for the added lift height. So you can buy a kit that includes shocks, buy a kit with adapters that will 'lengthen' your current shocks, or you buy a kit without and supply your own shocks that are long enough for that lift height.

 

With shocks: comes with 4 shocks.

Without shocks: comes with adapters that install on the stock shocks to extend them for when you add the spacers to the springs.

 

Gotcha. So installing BB using factory Rubicon shocks buy the kit with the adapters. Thanks.

 

Yep, if you like your current shocks there is nothing wrong with running adapters. Then in the future, you can move to a longer shock if you decide to.
