Overview:

Holley's Premium 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 (Patent Pending), 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 that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines. When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, P/S pump with reservoir, and an SFI certified damper w/hard anodized billet crank pulley. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation. The Premium Mid-Mount system comes with dress up pulley covers and an SFI certified damper. Partnered with this damper is a billet 6061-T6 aluminum hard anodized crank pulley. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Decent at dampening sound
Color: Grey, Color: Grey
This partition was easy to assemble and is stable. My husband and I both work from home, and the desire was to have a sound barrier. It definitely dampens the noise. If it was another foot taller, that would be even better at dampening the noise. Obviously, we still hear one another quite well, but the partition simply softens the noise of each other.

Easy Install, Great Quality, Mobile Partition
Color: Grey
This is the easiest install I've ever had in my life, took about 5 minutes. These panels come pre-assembled, minus the wheels, which screw into the base pieces in pairs. The material is a very pleasant "corporate grey" - I only worry about its color fastness over time. I needed a practical solution for my garage, which has glass garage doors that let in a ton of sun/heat and even with privacy film still parade around my tools and belongings visibly to anyone walking by. These partitions are functional for both of my needs, and if I have a visitor needing to park in my second spot it takes 5 seconds to wheel these out of the way.

Nice, convenient partition that absorbs sound
Color: Grey, Color: Grey
What stood out * Instant partition: This 3-panel foldable office partition helps to create quiet zones in a shared room, and it genuinely helped carve out a more focused space without a major renovation. The panels feel substantial yet easy to move thanks to the wheels, so I can roll them into position when I need privacy or a professional background for video meetings. I can fold them flat against a wall when I don’t nee them. The aluminum frame gives it enough rigidity to stay upright, and the gray finish is neutral. The height and width are generous for desktop setups, meetings, or study areas, and because it’s modular you can arrange it in L-shapes, straight lines, or even semi-circles. The mobility makes it flexible for dynamic spaces — roll it out for working hours, tuck it away after. * Sound insulation: It's heavy, which is better for sound isolation. The sound-dampening design isn’t miracle acoustic treatment, but it noticeably softens background chatter and echoes — enough to make video calls and focused work feel less disrupted. * Assembly is super easy, but I would recommend to have two people to make it easier. What to keep in mind * It’s not sound-proof like a built-in wall, so loud noises still carry; it’s best for softening ambient sounds, not blocking them completely. * The gray color is neutral, but if your room palette is bold you might want to accent with décor so it doesn’t look utilitarian. You can also tack posters and light pictures to the the gray frames. * It's pricey, but worth it in my opinion.

Decent dividers
Color: Grey
I think you will love these under the right circumstances. Number one the sound absorption is hard to describe because since the panels don't go to the roof sound can easily travel to the other so you and without being hindering but they do absorb sound to a certain extent. They also provide pretty good coverage for privacy in an office or dorm situation with ease. I wouldn't say it's easy to store but it does fold up pretty well and overall for the price it's an effective means of letting those around you know you need some peace. For the price it's a pretty good divider. It requires very little assembly and is relatively sturdy so all in all not a bad option. Until We Meet Again -Off The Grid Ken
