Complete GM Gen V LT Accessory Drive System w/ Alt, P/S, A/C, Water Pump, Belts, and Crankshaft Damper

Holley's Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design, where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. Among the many swap-friendly features are bottom heater outlets for clearance in tight applications. The Holley-designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with a baffled reservoir.

Great all around and durable. Will last a long time.
Size: Large-X-Large, Color: Black/Anthracite/White
Great hat for being lightweight yet holding the sweat it needs to while also being cooling with the air vent holes. Perfect velcro that moves and does not collect junk in the wash. Durable and is long lasting. Have used for many months and wear a visor daily. It is my favorite.

Great lightweight & breathable visor for the outdoors
This visor is nice & light-weight. I love the style & the tiny holes in front for breathability! I’m a huge Nike fan & appreciate the sturdiness, softness & comfort. It has a soft velcro adjustment, so it doesn’t scratch the back of your head, which is a plus. Value for the money is a little high, but well worth it since it’s my go-to hat for playing tennis, running or walking. Highly recommend this to others.
