Overview:

Holley's Mid-Mount Accessory Drive System is now offered for the serious racer in mind. If you need a front drive system for your LS engine racecar, they are now available without air conditioning and power steering depending upon your needs! 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 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, 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.

Woah, Shimmer!
Color: Late Autumn, Color: Late Autumn
I love cute little things like this with the spray bulb. They’re fun gifts. My daughter likes to shimmer sometimes. She kind of overdid it the first time. It does t take much to get a sparkly, fine shimmer. The photos are a bit exaggerated on the product page. You don’t have to “paint” your skin with it. It’s an easy application, and when used right really provides a nice accent. It’s light and has a quality look and feel.

So pretty!
Color: Late Autumn
This shimmer is beautiful! It applies smoothly and evenly and it sparkles absolutely beautifully. You can do one spritz for a very light coverage or a few to really glow! I love the applicator - makes me feel fancy. It was a little bit sticky at first but it dries quickly and isn't sticky after that. It's a really great product to brighten up your look. Highly recommend!

This is such a fun little product.
Color: Diamond White
This is such a fun little product. The shimmer is really pretty and fine, not chunky or glittery in a bad way. It gives a nice glow without looking overdone. Super easy to apply and a little goes a long way. I’ve used it on my face and collarbones and it looks great in different lighting. For the price, I’m honestly impressed.

Glitter Puffs
Color: Late Autumn, Color: Late Autumn
*Poof* and then there was glitter. Boko Highlighter Powder Spray, Body Shimmer Spray for Glitter Highlighter Makeup makes it as easy as squeezing a bulb. The biggest part of the assembly of the product is to male sure you remove the plastic cap and the rubber tipped end. If you miss either the spray will seem to not work. Once properly set up the powder spray bottle only takes a modest squeeze to dust the skin with instant glitter and glory. I love the look, the easy to use spray, and the bottle itself which has a simple but elegant feel to it!

Extremely fine shimmer- the air bulb works well for application- Even and controllable
Color: Late Autumn
This is a great way to apply a very fine sparkle. The shimmer is very very finely ground and it sprays out evenly with this air bulb. It does have a lid so there's no chance on it getting everywhere unless you leave the lid off. It also comes with a little plug in the hole so there's two mechanisms there to keep the glitter in the bottle when not in use it's very easy to use and apply and the spray pattern is very even. I got the golden shimmer which looks great with a tan or if you have warmer undertones in your skin. It doesn't require any sort of setter or glue + doesn't have any fragrance. It's a small bottle so it doesn't take up a lot of room.
