WP Xact Shock Preload reducing Spring Seat 23-

Our lowered spring seat replaces the oem plastic unit and allows a lower spring seat, suitable with shock lowering -40mm and -50mm options.  This can not be fitted to a std Xact 23- shock or the spring will touch the linkage assembly.  

Could possibly be used with other lowering amounts but spring to linkage clearance must be checked once installed to the bike.
