Overview:

With performance engines pushing redlines up higher and higher, alternators are being forced beyond their design. Holley's premium alternators are specially designed to tolerate 30% higher RPMs than conventional alternators and made in the USA. If you drag race, auto-cross, or just hot-rod your ride, know this alternator won't fly apart on you. Inside the attractive Holley housing is cutting edge technology. Every component was developed to produce cleaner, more efficient output compared to conventional alternators. Efficiency means you get more from a compact package. GM recently adopted this technology for the 2014 and later Corvettes. The attention to cosmetic detail on these units is above and beyond what you would expect too. The entire outside housing has been sculpted for a smooth silhouette that hides the ugly details we think of as alternators. The housings are smoothed to make polishing clean (no buffer cut marks trying to get in tight corners). Even the rear cover is aluminum so you lose that black plastic on your polished alternator. Available in Natural, black, and polished finishes. For that finishing touch, black pulley covers are available to give a simple but refined look on the 197-302 and 197-303. The 197-304 polished alternator already includes a polished cover. These powerhouses fit ALL Holley accessory brackets, as well as 4th generation F-body, most 1998 thru 2004 GM trucks, and many other applications.

  • Works with ALL Holley accessory brackets
  • 150 Amp Output

Amazing mattress
Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: Queen (U.S. Standard), Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: Queen (U.S. Standard)
I’m really happy with this mattress! From the first night, it felt super comfortable and supportive. It has the perfect medium-firm feel, not too hard and not too soft, which makes it great for a good night’s sleep. The memory foam adapts really well to my body and helps relieve pressure, especially on my back and hips. I wake up feeling much more rested and without soreness. I also love that it has a cooling effect. I usually get warm while sleeping, but this mattress stays comfortable throughout the night. Another great thing is that it doesn’t transfer movement, so if you share the bed, you won’t feel the other person moving around. Overall, this mattress exceeded my expectations. It’s comfortable, supportive, and feels like great quality for the price. I would definitely recommend it!

Comfortable and well made
Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: King
The firmness is great. Sleeps so good. Keeps us cool and forms to our bodies. I just hope it holds up for a few years. I have the 12 inch and my daughter that is 100lbs has the 10 inch we’ll see if this was as good of a buy as I think it is. Feels good and soft to the touch. I recommend this to anyone before you spend 2000.00 on a bed try this one it so very worth the money.

Couch yes. Sleep, no
Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin
I bought it for a daybed in the livingroom as a couch. It’s firm, but conforms to you(memory foam). Sitting is comfortable, however if I lay down it’s too hard. I can set a plate of food down next to me and it won’t move. So perfect for a couch, I wouldn’t be able to sleep on it

I am very pleased with this purchase😍

I’ve been sleeping on the EGOHOME 8 Inch Memory Foam Mattress in Queen size for a little while now, and I’m honestly very happy with it. The Queen size fits perfectly and gives plenty of space while still feeling super cozy. The mattress has a really comfortable medium-firm feel — supportive but still soft enough to relax into after a long day. I also noticed the cooling gel foam helps prevent overheating at night, which makes sleep much more comfortable. It arrived compressed in a box and expanded quickly without any issues. The quality feels great for the price, and there was very little odor after opening. Overall, this mattress gives great support, relieves pressure nicely, and has definitely improved my sleep quality. Highly recommend if you’re looking for a comfortable Queen mattress!

Great mattress for kids! It expanded quickly, has minimal odor, and provides a comfortable balance of softness and support. The memory foam relieves pressure well, and the cooling gel helps keep it comfortable throughout the night. Excellent quality for the price and a great choice for a child’s bed.
