Icon Air bump spacer needed for RXT leaf?

I have the RXT leafs that came with my my Icon stage 9 suspension. Instructions aren't quite clear to me. Do I need to install the spacer or can I leave it off for more up travel.


Final question, after full compression the air bump makes a weird rebound noise (not the click noise when it hits the striker plate). Is this normal?

The spacer is need if you are using the ICON RXT leafs & Bump kit.
(The spacer is removed on applications that use a taller/thicker leaf pack by another manufacture.)

 

Thanks now I know to leave the spacer on. So is it normal the the air bump makes noise like my windshield wiper when it’s dry?

 

The bump stops are emulsion, so since there is no dividing piston they will sound very different compared to coil overs or rear shocks. What you are hearing is normal.

 

Ok thank you very much for the quick response loving my new suspension.

 

Mine started making that noise too! Good description by the way haha.i wasn't sure how to describe that sound

 

That noise did go away. Only noise I noticed now is it hitting the striker plate.

 

I wish my spacer rings were only a 1/4 inch or so because I feel like I bottom out sooner and my shocks are about 5/8 from bottoming out.
