Pls measure your dimensions of your coilover as per our drawing required below and then choose the correct air spring .
NOTE for customized items (Require MOQ 10 PCS):
Customized products cannot be returned or replaced once products completed , we will not refund for any customized items, as it cannot be sold to other customers. pls try to confirm all the measurements before make order.
*Sealing part (B) =50mm -----Dia.of smooth section on damper above thread
*Top shaft diameter(C) =12mm
Don't understand why some air spring endplates must be made separated ? Read explanation as below------
It depends on the smooth section diameter (B), if it is larger than diameter of shocks thread (air spring root smaller thread diameter ),the air spring endplates must be designed separated two parts like this.
For example, M55*1.5-54, shocks smooth section diameter (B) is 54mm, it is larger than shocks thread part diameter（air spring root smaller thread diameter ）55-1.5=53.5, the air spring cannot get through the smooth section(B=54mm), so we have to make the endplates two parts, assembly air spring with shocks from both top and bottom direction (air spring screw from top, separated endplate screw from bottom)
