The Heavy Hitter Primary Drive Conversion Kit was designed for those wide-open throttle riders who just keep snapping belts. Why the Heavy Hitter kit is the best? Replacing a belt drive with a chain drive will lower the bike's efficiency, which in turn affects power delivery.

Chain drives are stronger, just not as efficient. Heavy Hitter's goal with this chain drive is to give you maximum performance by providing the lightest kit on the market! The primary chain drive sprockets are machined from 7075 T6 billet aluminum and have been put through the hardening process with the anodized black finish.

This kit comes with a high-quality o-ring chain to offer the longest lifespan. If you want your primary drive to perform even better you can use a standard non-o-ring chain, however, the lifespan of non-o-ring chains will be shorter. The provided o-ring chain is equipped with a master link, facilitating straightforward replacement without necessitating the disassembly of the swing arm.

NOTE: This conversion kit maintains your bike's original gear ratio, and OEM motor alignment. Your bike's fitment will be labeled on the motor sprocket and should always face outwards! 
-Aluminum sprockets always have a shorter lifespan than steel sprockets. The purpose of this kit is to offer maximum performance

  • Machined 7075 T6 billet aluminum sprockets

The rubber middle is not durable, it lasted less than 3 hours.
Color: 1 PC-Beef-Red
I bought this as I have bully/husky puppies (9 months old) and a pitt/doberman (9 years old). They are heavy chewers and destroy everything. I saw a video of this toy. The woman said that her dog chewed on it for a while (about 2 hours or so) she showed the ends visibly chewed, which I expect but it was holding up. The rubber middle seemed to hold up to. I received this yesterday. I had to take it away from them last night as they were chewing the rubber middle off. They had it maybe 3 hours. I didn't give it a lower star score as I will just cut the rubber off and give it back to them. So I was disappointed in the rubber middle not being more durable but the hard plastic it's made from is the strong material they need.

Smaller than pictured but still a good choice for LG-XL dogs/power chewers!
Color: 3 PC-Beef-Red, Color: 3 PC-Beef-Red
Fantastic that these come in a 3 pack - I wish more chew toys did this! The base for these chew toys is pretty tough! The center & ends are hard enough to withstand both my bully mixes & my Irish wolfhound/Great Dane cross. They’re safe enough for even the largest power chewers! (With Supervision) my American Bully got the rubber spikes chewed off in under 20 minutes which is mildly disappointing but he’s a true powerhouse & master destroyer of all chews so I’m not that bent out of shape about it. I do wish they were as large as they appear in the ad pics but isn’t that the game we all play ordering offline anymore? 🤷🏻‍♀️ • Pro Tip: smear this toy in peanut butter (xylitol free!), wet food mixed into a slurry with water or bone broth + kibble/treats, yogurt, or even pumpkin puree and freeze for a few hours & relax while watching all the organic engagement your dog gets out of this toy!

Heavy duty, excellent quality
Size: Small, Color: Textured Ring, Size: Small, Color: Textured Ring
I trust the Nylabone brand and would not buy a cheap substitute to save a few bucks. This ring is heavy duty. I got it for our 9-week-old puppy and it keeps her interested and entertained with all the little nubs. She uses it more as a toy than something to chew on, tossing it around and mouthing it. It's very hard so I'm not worried about her being able to chew off any little pieces at this point. This satisfies her for now and helps to keep her busy and reigns in some of her puppy energy. Recommend!
