Several different manufacturers look on rock auto I used kyb and went over to kyb struts they are a lot stiffer than stock but like it that way but the ones for the front on 2004 to 2008 are miss matched front to rear fronts are softer than the rear the ones for 2009 to 2011 are stiffer and better balanced same strut body different valving as kyb goes had emailed KYB to clarify as there was different ones listed for a Pontiac G3 depending on serial number
same rear shocks on all years
But If you want a softer ride Monroe OESpectrum they were on my newer 2009 Pontiac G3 when I bought it did not feel every defect in the road
