Yes, you can put a supercharger on a 5.3 LS engine. Supercharging is one of the best ways to get more power out of your engine without having to make extensive modifications such as replacing pistons or camshafts. Installing a supercharger is relatively straightforward and there are several kits available for the 5.3 LS that include all necessary components such as brackets, pulleys, belts, and all other hardware required for installation. Depending on the type of setup you choose (roots style or centrifugal) it may also require an intercooler system and additional fuel delivery components in order to ensure optimal performance from your new power-adder. With proper installation and tuning, adding a supercharger to your 5.3LS can result in significant gains in horsepower and torque numbers while still maintaining reliable daily driving characteristics - making it an attractive option for those looking for extra performance without sacrificing drivability!
