End members are supportable along a damper housing and dimensioned for securement to a flexible spring member. The end members include a wall with a first wall portion having an outer surface portion dimensioned to receivingly engage the flexible spring member. A second wall portion includes an inner surface portion dimensioned to receivingly engage a torsional isolator supported on the damper housing. A third wall portion extends radially outward beyond the second wall portion and includes a passage surface at least partially defining a passage extending axially through the third wall portion. The passage is dimensioned to receive a projection of the torsional isolator. End member assemblies including such an end member as well as gas spring and damper assemblies and suspension systems are also included.

End members are supportable along a damper housing and dimensioned for securement to flexible spring member. End members include a wall with a side wall portion including an inner side surface portion. First projections extend toward a first inner edge with a first shoulder surface portion faces a second end. Second projections extend inward beyond the inner side surface portion toward a second inner edge with a second shoulder surface portion facing a first end. Second projections are spaced axially from first projections such that a groove is formed inward of the inner side surface portion between first and second shoulder surface portions. End member assemblies including such an end member as well as gas spring and damper assemblies and suspension systems are also included.
