Our FS19_419 line comes in 3 options and will work with tires down to 3.93. 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 insertz. (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. ***All products are made to order.
