FlubberStufferz Performance Inserts for 1.9 wheels and 3.85 tires.

- Forward Propulsion Technology, industry first technology we introduced with our 24th scale SlymeBallz Performance Inserts. We brought that same tech up to our FlubberStufferz line. In the normal rotation direction, this takes deformation caused by conforming and pushes it behind the tire to create a pushing motion to help get through the tuff stuff!

-Dual Direction Conforming Rates, something we've been playing with for months! With some cleaver placement and design work, we've been able to change the conforming rate when the insert rotation direction is simply flipped. This does a few other interesting things as well... When reversed, the 1st stage gives easier, and depends on the 2nd stage for support. It also deflects deformation differently and places that deformation on the contact surface.

Our inserts have a soft outer stage, and a stiff inner stage. They conform to terrain as required and are well tuned for all rigs varying from sub 5 lbs comp rigs to 12 lbs scale rigs! Sidewall support is incredibly stout, which gives un matched turning and side hill performance.

We have had a strong focus on fitment and leaving no room for improvement. We put the time into design, prototyping, testing, and production to give you the best possible product. Made in MN, USA.

Baseline weights are listed, your choice will depend on the rigs weight, your desired conforming rate, and the tire itself can have an impact on support.

🟢 Soft (sub 6lbs) this is our original/standard insert, it is very soft and is reccomended for light weight comp rigs for use in fronts. We keep things extra soft for those looking for ultimate conformity yet stout side wall properties. Comes standard with our Directional Conforming Rates, and Forward Propulsion Technologys.

🟢 Med (sub 9lbs) this is our mid range with a thicker 2nd stage for extra support. For use in either front or rear. Comes standard with our Directional Conforming Rate, and Forward Propulsion Technology.

🟢 Firm (10 lbs). Made from our standard material, which gives a plush first stage to allow conforming to happen, yet utilizes our No Flat stage to give plenty of support for heavy rigs and absolutely the best side hill performance. Comes standard with our Directional Conforming Rate, and Forward Propulsion Technology.

Package contains 2 tire inserts.

(Insertz are printed in our brand colors. They will come in one of 2 colors, random selection, green or purple)

We recommend venting your tires when running our Performance Inserts. They are waterproof, temperature and mildew resistant, and designed to support without the need for sealed setups.

These are made to order and take approximately 2-3 weeks or more depending on the workload. Appreciate your patience and support!
