Depending on which vehicle you’re planning on swapping an LS into, you’ll need to keep in mind that power steering pumps (much like water pumps and crank pulleys) follow the same spacing guidelines and vary from one auto to the next. Make sure to check the list below before selecting your LS power steering pump to ensure proper fit and placement.
Corvette, CTS-V, SS (sedan), & G8 are represented by a -1 (dash one) spacing
1998-2002 Camaro & GTO are represented by a -2 (dash two) spacing
All trucks & 2010-2015 Camaro are represented by a -3 (dash three) spacing
