Zeus 24V 4kW Low Turn On (LTO) 1"-2" Single Foot Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact onthe  alternator lifespan.

Chewing pups love them.
My 8 mo Morkie loves them . The other two won't touch them . They're heavier than I expected but Belle doesn't seem to mind that. Great for dogs that like to chew!

Meh..., I'll stick to fave pig ear chews
Only 4 for $6, idk these don't last long. I wanted to try them because my dogs love being spoiled but I think I'll stick to pig ears at a discount from Petco. They are very hard, some chews crumble or soften as the dogs knaw at them during the day. However these chews didn't last longer than 10 minutes compared to actual no rawhide alternatives I have used. These didn't do that. No upset stomach so that's a plus. The smell was similar to pig ears also, texture was different. No slimy residue w/ it unlike with the regular 100% pig ears. Helped with plague build up but there is still plague on insicor tooth. Probably won't buy again, meh.

bag came ripped
bag came ripped so the chewy pig ears were not chewy they were hard, I didnt even give them to my dog. The worst part is they are not returnable or refundable - what a waste of money So not acceptable.
