Bravo spacers ?
 

I have bravo xr drives with 1" spacers and switching to sport master bottoms will spacers work? They list different spacers for sport master and wondering why.

Just installed a set of 1.5" spacers on my Bravo XR sportmasters last summer. Brett at Blades has a rental program - you can try before you buy. I was having trouble with excessive slip and Brett suggested the 1.5 inch spacer. Was very happy with the result. The sportmaster uses a different spacer from the regular Bravo. You will have to purchase spacers to fit your sportmaster lowers.
