The KS3 Cobra Bag Spring

Finally!!! The next generation of the Kewlus Cobra Bag Spring is here - the KS3! The first batch of KS3 Springs is offered at a discounted price but numbers are limited, so jump on kewlus.com/ if you want one. This spring opens up possibilities such as a shortened version of the cobra bag that is ideal for small kids as well as for use as an upside-down or horizontal cobra bag - something that no other cobra bag offers!

Incredible as always. Not only answered my question regarding the spring caps, but got to see it in action in different places as well. Can't wait to see how it looks like in the DIY set-up. Keep up the amazing work, mate!

[@Kewlus]

Thanks mate!!!

Mines make it on 6th yes🎉🎉🎉 thanks reedy

[@stanleyipkiss509]

you should definitely look into making different solid colors for the bag

[@Kewlus]

Yes I will. Thank you

[@DanielThomasArgueta]

@@Kewlus I'll buy once there's a solid red bag. 🥊

[@Infamoustr85]

Just bought the new spring. Will give my feedback hopefully next week. FYI I'm in Melbourne if that helps.

[@Infamoustr85]

Ok so I've had a couple of weeks with it and noticed something important which might be helpful for others. The base needs to be secured more than with the previous spring. I was using the previous KS2 spring with the paddles and sand bags. When I changed to the KS3 spring I honestly didn't find much difference other than that I can now throw in a few uppercuts. Then I noticed I had to keep repositioning the bags with the new spring. I then added 2 x 15kg dumbbells on top of the bags. Wow what a difference the spring is with the base properly secured. I think the new spring must transfer the load down to the base. Hopefully this makes sense.

[@Kewlus]

Thank you for the feedback!!! Yes the KS3 needs the base to be more sturdy to get the full performance improvements

[@leorefuerzo832]

Horiontal set up is good for roundhouse kicks

[@aherosquest4536]

Dang it. I just got the KS2 version.

[@Kewlus]

You can upgrade at a later stage 🤙

[@cdt6857]

Awesome! Is this going to be available in the all in one bundle?

[@Kewlus]

Yes it is already available as a bundle here: kewlus.com/pages/cobra-bag

[@dragonfruit5271]

Hey Reedy, KS3 looks amazing in action! Thinking of upgrading from the diy KS2 spring. Looks like there is metal end caps attached to the spring. How am I suppose to attach it to the upper 3/4 pvc pipe and the bottom 3/4 galvanized pipe/nipple? KS2 slid into both and then we used alligator clamps. How would KS3 be attached to the diy set up?

[@Kewlus]

Would just slide on and you can simply use duct tape to tape the connectors in place

[@dragonfruit5271]

@@Kewlus Will you be making a video to show how the KS3 looks and and performs for those with diy set up?

[@Kewlus]

Yes

[@richiestarks6163]

Update; The new KS3 spring arrived and the recoil is quick, much more solid and give me (6’2”) the perfect punch for my. As fast as base, it moves a bit much and thinking if a 1 inch bar would be more solid to stop the vibration on the bottom.

[@meowdownkio]

Hey! i like what youre doing. My question is how hard you can hit this thing without worrying it'll break? I'm thinking of pure powershots. Thanks!

[@Kewlus]

My ceiling is not strong enough. If you attach it to a solid beam then you should be able to smash it

[@joey_ricciardi117]

Question, please. What is the thickness of the rods? Will it fit in my Ringside post/base pole? Your spring definitely seems better than the Ringside and Title bag (I have both).

[@Kewlus]

Hi Joey, it's based on my original DIY/Kewlus design, which fits onto a standard 3/4 inch plumbing pipe. It's backward compatible with all my previous designs, including the DIY integrations. I did not design it to fit any other types of commercial cobra bags, but if the diameter fits then you may be able to upgrade. The inner diameter of the connectors is 27mm.

[@joey_ricciardi117]

@Kewlus great, thankyou for the quick response. I may even just buy your whole setup. I just hate for these other 2 cobra bags to go to waste.

[@Kewlus]

Thank you brother - I know what you mean. Those other cobra bags are impossible to upgrade and if something breaks, like the spring (and they don't last long), it's almost impossible to replace. That's exactly why I developed the modular concept.

[@kevincorbett4161]

Hey Reedy, don't think you send to UK, what are the specs for the new spring and any idea where I could get one. Cheers

[@Kewlus]

I do ship to the UK from a warehouse in Canada so yes you can order from the UK. There may be import tax at your end though which I don’t cover. Add a product to the cart to get a shipping cost. It’s not too much.

[@krixxusjg7452]

Hi Reedy, I want to order the whole kit with the KS3 spring but I'm too dumb to find which components you need to basically have the whole core kit, can you help me?

[@Kewlus]

Sorry, my bad. I've just added a KS3 Core Kit to the Modules page: kewlus.com/pages/cobra-bag

[@EG-tw1kj]

When will the platform paddles be restocked?

[@Kewlus]

They are in the process of getting upgraded. The new version will be released around February next year

[@theweekendoddz1176]

what's rhe dimension of the spring? thickness, diameter and length

[@jazzcat1056]

Can you use the base paddles with this or need to build the one you mentioned

[@Kewlus]

The paddles may not be sturdy enough for the KS3, so I highly recommend making the thicker baseboard or having a local carpenter or cabinet maker make it for you. I’ll be releasing an upgraded version of the paddles early next year

[@OHMASIA1]

@@Kewlus Your kidding me, I just got rid of my old board and kit to replace with the full new kit and paddles-I just spent 75 on paddles that are going to be useless to me and i need to buy a new bottom board!

[@NB780]

I just got my K3 spring going on day two and I'm constantly adjusting the spring and tightening it to the two metal ends (loctite and plumbers tape doesn't seem to be working). It gets annoying after two mins of use, I can feel it loosening. K3 might be faster than the k2 but having to adjust it ruins my workout.

[@Kewlus]

Try using epoxy and leave it to dry for 24 hours

[@MrRenaissance17]

Can this spring be used with a 3/4 inch galvanized pipe? I'm thinking about upgrading from the KS2 to the KS3

[@Kewlus]

Yes it’s compatible 👍

[@mr.freddie]

would the KS3 without the connector fit into the rubber caps?

[@Kewlus]

No it would not fit because it’s a bigger diameter spring. The connectors at each end of the KS3 slip perfectly onto the Click Bar or the 3/4 inch pipe for DIY. There’s no need for the rubber end caps with this new spring

[@adamroddis3218]

Would the small ball be a better option due to it being harder to hit?

[@Kewlus]

It definitely more challenging and moves a little faster

[@adamroddis3218]

Does this new spring fit on the original multi base?

I I am a US amature boxer out of Northern Va & have been using my cobra bag from you since 2021 and its been amazing & I have never had a single issue nor complaint. I keep one in my trunk disassembled as well for when I am on the road and want to pull over to a part and get some work in. It never takes more than 5 mins to get everything set up and going. I’ll be a lifetime customer for sure. I believe in you. Thanks again
