JConcepts Slam-Tech Monster Truck Tire Inserts

From JConcepts:
Tire inserts can be just as important as a performance tire, and in many instances, proves to assist handling in the most difficult conditions. The new Slam-Tech inserts by JConcepts are a new light-weight alternative for RC monster truck racing. From a competitive standpoint, jump landings are extremely important, but perhaps most important in the monster truck community where the slightest advantage can produce a huge victory in a single racing pass.

In testing, using a hard, closed cell type material in the tires creates smoother rolling speed, more balance in the tire and helps minimize rebound in the tires off jump landings. The Slam-Tech is a new generation of insert with molded exclusive materials with radial details found on off-road racing inserts. The material is white in color and lightweight by nature surprising even the most critical of builders and racers. The inserts are compatible with JConcepts tires such as the 2.6” Renegades, Knobs, Launch, Racer, and Runner tires and fit inside like a glove.

Traditional open cell inserts weigh ~38gms each, while the Slam-Tech inserts weigh in at ~24gms each. This lowers the rotating weight of any RC monster truck by a considerable amount thus providing more acceleration, better in-air control, less un-sprung weight, and less overall weight. The Slam-Tech inserts are a win / win when it comes to performance items and easily one of the best hop-ups to add when it’s time to upgrade the vehicle.

The product is always backed by JConcepts customer service, supported, and developed by professionals with style and authenticity. JConcepts Slam-Tech inserts are molded in an exclusive formula proven for performance while being driven and tested by experts in the industry. Look for reputable dealers and distributors and demand authentic and licensed products – choose JConcepts.
