LS Front Accessory Drives for Original Equipment ComponentsThese Front accessory drives are the perfect fit for any LS swap. They’re designed to use original equipment balancer waterpump alternator pulleys and idlers for ease of getting replacement parts. The brackets are machined aluminum and powder coated black for long lasting good looks. The alternator and powers steering bracket kit is available with or without a new power steering pump and reservoir so you have an option to use an existing f-body pump. The AC kit comes with a Sanden style 7 piston compressor for excellent cooling. These drives are great to use with pull out engines since you can reuse a lot of the components that your engine came with. They all come in three different configurations since the LS engines were built with three different balancer and waterpump lengths. Short length for Corvette CTS-V and Pontiac G8. Medium length for 98-02 Camaro / Firebird and Pontiac GTO. Long length for Truck SUV and 2010 up Camaro. These well thought out accessory drives help make your LS swap quick easy and affordable
