Important Notice: When installing, make sure your chain tension is not tight! Any chain drive that you install should have loose chain tension! Please check the fitment tab for important motor info.

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

Withstands very aggressive chewing
Color: Blue
We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Great chew toy

I bought this almost a year go. My dog is still chewing on it! Nothing last this long with her. She is a 100lb Rottweiler that is a strong chewer.

Well loved
Color: Blue, Color: Blue
We just got this sweet girl from the shelter a few days ago. She's had this toy for 2 days and already chomped off one of the legs. She does have other toys so she doesn't play with this one all the time but she does like it a lot! It's very hard and durable on the ends. But as you can see, it's not indestructible. She carries this little guy around the house like they're BFFs. It's super adorable.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.
