Chevy LS ProCharger P-1R Modular Accessory Drive Supercharger Kit
ProCharger 1LS400-P1R combines a P-1R supercharger with the Chevrolet LS modular accessory drive.
Package configuration
Select non-intercooled or 3-core / 825 hp intercooled configuration. Intercooler ratings describe capacity, not guaranteed engine output. Includes the LS water pump, six-rib accessory drive, eight-rib supercharger drive and ProFlow bypass valve. The full bracket package provides alternator, power-steering and A/C mounts; alternator, power-steering pump, compressor and crank balancer are separate. Intercooled packages include universal charge tubing requiring installation planning. A carburetor hat is optional.
Bracket, finish and gear choices
Full accessory brackets are available in satin, black or polished. Satin-only omission choices deduct $300 for power-steering hardware, $200 for A/C hardware or $500 for both. Black accessory brackets add $250; polished add $350. Helical supercharger gears add $110; black housing adds $295 and polished adds $450. These selections are included in the displayed variant price. Supercharger-bracket finish and water-pump finish are separate selections.
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.
