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 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, and an SFI certified damper w/hard anodized billet crank pulley. All pulleys and the belt are supplied. Even heater hose adapters, 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.

Features:

  • Bracketless accessory mounting with ultra-easy assembly
  • Bottom outlet heater hose options for swap application clearance

Sturdy, high quality, and protective
Color: Green, Size: 15-inch for New MacBook Air
This is my third TomToc laptop sleeve. Each time, I bought another, less expensive brand first and returned it. TomToc offers the best protection in a soft-shell sleeve. Immediately when you open it, you feel the higher quality material and density. It’s not heavy, but it is thick padded and doesn’t easily bend with pressure. The zipper is built to last, sturdy, and easy to operate without that chintzy feeling from cheap zippers. If you pay attention to the construction, you quickly see why it’s about double in price. There is an inner pad to protect the laptop from not just drops and shock, but also from the zipper. The corners are reinforced and add extra protection. It is definitely worth double the price.

Great Laptop Case !
Color: Black, Size: 13-inch for New MacBook Air & Pro
This case is reallllly nice and durable, the cushioned corners is what really makes this case special imo. The outer layer is a nice durable think fabric. It fits perfectly. The only downside is the zipper traction is not as smooth as I would like ,,, but I guess I can fix that with some oil/wd40. I would recommend this laptop case ! 👌🏽👌🏽👌🏽

Better Lips, Better Fit, Less Nonsense
Color: Black, Size: 13-inch for New MacBook Air & Pro
I tested this sleeve with a 13.6” MacBook Air (M4), and the difference is immediately noticeable. First thing: fit. This one actually holds the laptop in place. The padded “lips” in the corners create just enough resistance that you have to guide the MacBook in and out. It’s not a loose drop-in like other cases — it feels controlled. If I shake it, there’s barely any movement, which is exactly what I was looking for. Second: build quality. The stitching is clean and consistent — almost surgical compared to the wrinkled mess I saw on another model. The outer fabric stays flat, no weird waves or cheap-looking folds. The interior lining is softer and thicker too, so it feels more protective without being bulky. Third: structure. I even did a quick “real-world” test — stood it vertically on a mattress, zipper open, applied pressure from the top — and it held its shape. The other case I tried would have collapsed immediately. This one actually feels like it can handle normal use without transferring pressure straight into the laptop. The external pocket is simple but practical. It fits the charger brick and cable without interfering with the main compartment, which keeps the laptop fit intact. Only downside: I could do without the orange accents. A full black version would be perfect. But honestly, that’s cosmetic — functionally, this one does what it’s supposed to do. At around this price point, this feels fair. Not luxury, not overhyped — just a well-executed, practical sleeve that gets the fundamentals right. Bottom line: not perfect, but finally something that feels properly made and actually holds the laptop instead of just surrounding it.
