    This complete GM Gen V LT4 accessory drive system pulls the alternator, power steering, A/C, and water pump up and in tight for swap applications, adding a hydraulic power steering solution most swap kits lack. A splined dual-bearing system removes belt-load stress from the power steering pump's internal bearings for long life, and the supercharger drive keeps the original belt path and tensioner.

    • A/C Compressor Included: Yes (SD7)
    • Accessory Drive Style: Mid-Mount
    • Alternator Included: Yes, 150 Amp
    • Application: GM Gen V LT4

    • Finish: Black
    • Inlet Size: 35.4mm/1.4"
    • Material: Cast Aluminum
    • Oil System Type: Dry Sump

    • Warning: California Proposition 65
    • Warranty: Manufacturer's Limited 90 Day Warranty
    • Part Number: 20-221BK

    Includes a throttle body angle-correcting adapter for easier intake tube routing on swap applications, A/C line adapters, P/S hard line adapters, and bottom-outlet swivel heater hose options for clearance. This version is for LT4 dry-sump applications; a wet-sump version is also available.
