Complete GM Gen V LT5 Accessory Drive System w/ Alt, P/S, A/C, Water Pump, Belts, and hardware. Black Finish

Holley's complete accessory systems for LT4 and LT5 applications have all accessories pulled up and in tight. Plus, they add the much needed hydraulic power steering solution. There are no shortcuts here. Holley incorporates a splined dual bearing system that eliminates all belt stresses on the P/S pump's internal bearings, assuring long life. The supercharger drive maintains the original and optimized belt path and tensioner. The accessory layout is as if the original manufacturer had designed it for your swap application. Included with each drive system is a throttle body angle correcting adapter that better positions the TB for swap applications as opposed to the aggressive original application intended angles. Versions of these accessory drives are available for both wet and dry sump applications.

Features:

  • Adds power steering without any belt load on the P/S pump
  • Notably more clearance to swap applications than other options
  • Original equipment look
  • LT4 style premium alternator
  • LT4 style water pump design
  • Compact SD7 A/C compressor
  • A/C line adapters included
  • Type II power steering pump
  • P/S hard line adapters included
  • Bottom outlet swivel heater hose options for swap application clearance
  • Throttle body angle correcting adapter for easier intake tube routing on swap applications
  • OE pulley ratios for optimal accessory performance, allows for larger SC crank pulley
  • Available LT4/5 dry-sump & LT4 wet-sump applications
  • LT4/5 specific accessories available for plumbing oil cooler and PCV oil separator OE system

It works well.
Size: 8 Fl Oz (Pack of 1)
Great product that delivers on what it says it does. This won’t fix a mechanical problem or damaged component, but it will fix a stuck float, varnished tank, gummed up jet, or partially blocked emulsion tube.

It Works
Size: 8 Fl Oz (Pack of 2)
This stuff works. I added it to my four 5 gallon gas cans before filling them up. I’ve used 10 gallons of gas in my lawn tractor so far and can tell it likes it. I do annual maintenance before summer and check or change the spark plug so it performs the best it can. I have 508 hours on it and with this it seems like it idols smoother, which indicates it has helped in the carburetor since I haven’t had to remove it and clean it. Works great.

Great product
Size: 4 Fl Oz (Pack of 1)
Used this stabil in my rider after first start of the season. Machine running rough and uneven. Drained old fuel and added it. Within 15 minutes at full throttle it began to run normal. No back fires and engine back to normal. There will always be a bottle of this in my garage.

Works Great
Size: 8 Fl Oz (Pack of 1)
I"ve used Stabil gas treaments for year but never this particular type. With gas the way it is, I decided to see how it might help my mower and also my older truck. My older push mower which admittedly doesn't get pampered and petted seems to love it. Either it's grateful to get anything special or this stuff really has helped. The first tank seemed a little smoother but by the second I could hear the difference and feel it with the smoother sound and seems more power. It's easy to mix and use and Stabil is a well known reputable company.

Easy and worked seamlessly with the new Apple MacBook Pro
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
This was our first (Apple MacBook Pro M4) and big purchase directly on Amazon. I was not concerned about the order and product, but more concerned about the AppleCare+ not being connected directly to the device (after reading some reviews). However, I am happy to report that this was the first thing I checked as soon as we set up our computer. We are set for 3 years ... so thank you, Amazon and Apple, for working out the backend stuff and making our lives easier. It worked for us. It was easy, and I am happy with the overall quality of the process. Oh, don't forget it was cheaper than buying yearly from Apple directly.
