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.

High-Quality, Long-Lasting Fabric Wallet - Exceptional Value
I recently purchased the Carhartt Men's Billfold and Passcase Wallet and have been nothing short of impressed with this product. Both its design and functionality have far surpassed my expectations, making it an indispensable accessory for daily use. The moment I unboxed the wallet, the quality was immediately apparent. The fabric is thick and sturdy - a clear hallmark of Carhartt, renowned for its durable gear. The stitching is clean and robust, with no loose threads, reinforcing the fact that this wallet is built to stand up to heavy use. The wallet’s design and layout are well thought out. With ample compartments for cash, cards, and identification, it allows for easy organization of your essentials. The separate passcase is an excellent feature that enhances the wallet's utility, offering quick access to your ID and frequently used cards. Despite the impressive storage capacity, the wallet maintains a slim profile, ensuring it fits comfortably in any pocket. Aesthetically, this wallet doesn't disappoint either. The fabric has a rich color, giving it a rugged yet sophisticated look that's suitable for both casual and formal settings. The embossed Carhartt logo is a symbol of quality and durability that aligns with the brand's reputation. What I truly appreciate is the wallet's longevity. Over time, it has proven its durability without any signs of wear and tear. The fabric has softened slightly for a more comfortable feel while maintaining its shape and strength. In conclusion, the Carhartt Men's Billfold and Passcase Wallet offers exceptional value. If you're in need of a new wallet, I cannot recommend this product highly enough. Its superior quality, robust design, and practical features make it a smart investment that, I believe, will endure daily use for years to come.

Rugged, Reliable, and Built to Last
I picked up this Carhartt billfold wallet a while ago, and it’s exactly what I expected from the brand—tough, well-made, and built for everyday use. It’s holding up great, even after months of being stuffed in my pocket, dropped, and tossed around. What I Like: Durable Materials: The leather and stitching are rugged and high quality. It still looks good and hasn’t shown signs of wear. Plenty of Storage: There’s more than enough space for cards, cash, and ID, and it doesn’t bulk up too much. The removable passcase is a nice bonus. Classic Look: Clean, no-nonsense design. It has a workwear vibe that fits the Carhartt name perfectly. Comfortable to Carry: Even fully loaded, it fits nicely in my back pocket without being uncomfortable or bulky. Feels Like It'll Last for Years: You can tell this wallet was made with longevity in mind. Final Thoughts: If you want a simple, reliable wallet that won’t fall apart on you, this one’s a great pick. It looks good, performs even better, and lives up to the Carhartt name. Highly recommend for anyone who values durability over flash.

Overall it's a pretty nice wallet, and its different, unique.
Color: Carhartt Brown
This is a nice wallet. I am deducting one star for the reason another buyer noted. The card pockets are extremely tight. A solution that I came up with was to take a plastic putty knife and push down inside the card pockets and stretch the material out, this helped a bunch! One thing I really like, the material is not as slick as a leather wallet, so if a person has trouble with their wallet sliding out of their pocket, I think this one would be less likely to do that. Overall I'm pretty happy with it.
