Chevy LS ProCharger F-1R-103 Modular Accessory Drive Kit

ProCharger 1LS400 combines the selected F-1R-103 supercharger with the Chevrolet LS modular accessory drive.

Package configuration

Choose non-intercooled or 3 core 1300 hp intercooled configuration. Intercooler ratings describe capacity, not guaranteed engine output. Includes the LS water pump, six-rib accessory drive and 8-rib supercharger drive. Straight-cut gears; helical gears are not offered on these heads. Full brackets support alternator, power steering and A/C; accessory units and balancer are separate. Intercooled packages include universal charge tubing requiring installation planning.

A ProCharger Race bypass valve is included. Specify valve discharge, mounting material and finish with the installation details.

Bracket and finish choices

Select full brackets in satin, black or polished, or a satin bracket layout omitting power steering, A/C or both. Supercharger housing finish is included in the variant price. Supercharger-bracket and water-pump finishes are separate choices.

Engine and installation fitment

For standard-deck, wet-sump Chevrolet LS engines with aluminum or iron blocks. Not for LS7, VVT or tall-deck combinations. Iron-block installations with power steering may require minor modifications. Confirm engine code, block material, induction, chassis, mounting height and clearance before ordering. Engine-family compatibility does not establish direct vehicle year/make/model fitment.

Supporting components

Requires a compatible Innovators West or ATI crank balancer; crank pinning is recommended. Match the balancer to the selected supercharger belt drive. Uses a compatible GM truck-style alternator, GM Type 2 power-steering pump and Sanden SD-7B10 six-rib compressor when fitted. Supercharged power steering requires a remote reservoir. Plan fuel delivery, calibration, charge plumbing and vehicle integration with your installer. Supercharger mounting position and optional hardware require review for the actual engine and chassis.
