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.

Emotional Support Lizard
Size: 15 Inch
This was my Goldendoodle puppy's first toy, and a year later, it's still his favorite. It was light enough for him to play with it at 9 pounds, but big enough that he still loves it at 40 pounds. He carries it around, slaps his brother with it, throws it and chases it, sleeps with it, etc. He enjoys his stuffies also, but he returns to this one repeatedly through the day, so I know he loves it. It's a bit discolored, but still fully intact. If you have a dog with a soft mouth who isn't prone to chewing, this toy is perfect. I've purchased extras to keep in the emergency supplies in both the house and the car.

Not for puppies or dogs who enjoy chewing toys.
Size: 25 Inch
NOT FOR PUPPIES OR CHEWERS! If you have a dog that is teething or enjoys chewing on toys for soothing this is not the toy to buy. My 4 month old ate the sneak head off and the inside plastic ball squeaker was exposed and fell out and my puppy swallowed it. I tried to take it away from him but it was too late .. he already swallowed it. This caused serious vomiting days later in my pup. I’m not likely to leave negative reviews unless I truly have a horrific experience and this toy provided just that. 0 stars.

Cost effective option to find what kind of toys you new small pup will enjoy.
Color: 12 PACK PUPPY TOYS
This was a great puppy toy assortment. It is great because it has different types so you can figure out what types of toys your new pup will enjoy. This package is only suitable for small dogs. Also, I do t think they would be good for aggressive cheers. But if you are looking for a cost effective bunch of small new puppy toys this is perfect. There was no smell, the sound of squeaker were average high pitch, soft and moderately durable, design and appearance were generic. Not high quality but a good assortment. Not suitable for long term use IMO.

Love this and very durable!!
Color: Blue Spider
This spider is HUGE! It's sooooooooo nice! My 3 boys love it! They love chewing on all the legs and it's so big that they can all lay around it and each chew on a leg at the same time! They also play tug of war with it at times! It's stuffed with a cushiony material. It does not bounce. It's lightweight. Has no smell. It's so much fun for my boys! Love it! It has great durability as my one boy who literally destroys all his toys has not broken it and they've had it for 3 months so far! This alone speaks volumes! Highly recommend!
