RC Crawler 3D Printed Tire Foam Inserts | 1.9 x 4.75 Dual Stage | ALL NEW! | All 4 inserts included

All new dual stage 3d printed foams for your rc comp crawler or trail truck. Using a significantly softer material that what is currently offered, we are able to adjust the inner ring firmness independent of the outer ring! Outer ring material is even softer than what the inner is made from. These still retain the incredible sidewall action you have come to expect. Even better, this softer material is proving to keep its performance even in temps that drop below 30 F.

Now you have a chance to really dial in the inserts to your liking. 

Check out the video in the listing images -  this is a medium inner and soft outer! 

These are 1.9 x 4.75 or approx. 110Mmm tall. They will fit an assortment of 4.75 tires like the Proline Hyrax, KM3, Krawlers and more! 

Please note these are not offered in a stiff option, best to use the 95a options. 

OUR PROCESS

We’ve been 3D printing since 2017, shortly after 3D printers became readily available.

Here at Poptarts Prints, we custom modify each printer in the shop to enable a new and improved printing process. This allows for higher flow and faster speed to ensure your inserts arrive at your door sooner than others. Due to this process, you’ll never have to worry about layer separation, and each tire insert will have the right amount of flex and a rock-hard sidewall.

** Thanks to Missouri Scalers for featuring PoptartsPrints3D tire inserts in their 4th Annual Rigs and Coffee RC crawler event! **

INSTALLATION

Quick and easy to install! Simply put the 3D printed foam insert inside of your existing tire and reassemble the wheel. Feel free to contact us if you have any trouble with installation and we’d be happy to help. No break-in time needed – ready to use right out of the box! You’ll instantly see the difference in your rig’s performance and capabilities.

FEATURES

• Won’t break down in water.
• Soft enough to allow the tires to conform to the shape of the rock the truck is crawling over, while stiff enough to maintain a firm grip during side hilling.
• Do not require regular maintenance, unlike traditional foams.
• 3D printed with a trusted TPU filament.
• Comes in a variety of sizes and softnesses – if you don’t see what you need, message us!

Fast shipping and fast response time.

** These tire inserts are a gamechanger if you’re serious about crawling competitively. Improve your TRAXXAS or Axial RC crawlers’ performance, tackle obstacles like never before, and win competitions! **

Designed by D440 on Cults 3D – if you have your own printer, you can buy the file to support the designer and print on your own.
