There is no particular strut--- based on the towing package.
BUT there is a particular strut- based on the size of the wheels.
18 and 19 inch wheels use the same OEM strut.
20 inch wheels use a different OEM strut.
If you want to go with ACDELCO / GM original equipment- they have struts for wheel codes QCW, QLW, QUP.
or another with just QQD
it would be listed under the parts.
Or you can buy aftermarket- and see if they make a reference to wheel size---- or its a 1 size fits all
