Holley designed this 20-138BK High-Mount Complete Accessory System for GM LS engine swaps. This complete kit in black has everything needed for the application including accessories, pulleys, tensioner, as well as a serpentine belt that are manufactured by OE part suppliers many of which are on production cars today.

Universal brackets fit virtually all common LS engines regardless of water pump and harmonic balancer offsets, reducing cost and complexity compared to competitive products.

This kit is ideal for crate engines, take out motors and engine builders. The OEM spec flanged head hardware is included to match your factory LS engine hardware. OEM quality die castings feature clean looks as well as durability.

This simple, dedicated installation kit allows easy fitment to Corvette, F-Body as well as Truck drive offsets.

When we say "complete," we mean complete. The High-Mount system comes with everything you need: A/C compressor, Alternator, P/S pump, Tensioner Assembly, Idler Pulley as well as the alternator harness pigtail.
