If for what ever reason you don't have, don't want or can't fit the mechanical fan on your LS setup, then this ones for you. Most electric fan setups just simply don't move enough air to keep your engine cool.
That is why we developed this two stage setup with 4 x 9" fans with each fan pulling 590 CFM! Fitting in every the tightest spaces with a total depth of just over 2". We wire two fans diagonally to the low speed and the other two diagonal to high speed, creating a two stage system.
