We have 3 SS Inducer Spacer Options.
 
1.  The .875 spacer is the standard spacer used with todays machined shaft inducers and is included with the purchase of a HT-HS500s.
2.  The 1.300 spacer is used to move the inducer further forward - Shaft machining is required.
3.  The .600 spacer is used to fill the void in an impeller that has been machined for the (HT-HS500L) inducer.
