FSpec17_419

The FSpec Performance Insertz have a stepped inner ring designed specifically to be compatible with SpecRC wheels. 

***These are specifically for 1.7 SpecRC wheels***

The 4.19 version will fit 1.7 x 4.19 tires, such as the Pitbull 1.7 Rocker. 

🟢 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. This does not have our "No Flat" 3rd stage, this keeps 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 insert that comes standard with our "No Flat" 3rd stage. This provides support for either front or rear and keeps the tire from appearing flat yet still allows for conformity in the 1st and 2nd stages. The no flat stage will indeed conform under heavy load when required to. Also comes standard with our Directional Conforming Rate, and Forward Propulsion Technology. 

🟢 Firm (10 plus lbs) this is our new Heavy Duty Insert, and replaces the old HD insert. They are made from our standard material, which gives a plush first stage to allow conforming to happen, yet utilizes dual No Flat stages to give plenty of support for heavy rigs and absolutely the best side hill action in the Insert Industry. Most will find the medium insert to be sufficient for support. But if there is any doubt, the new Firm is here to ease those concerns! 

Package contains 2 inserts.

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