Slam-Tech Foam Tire Inserts for 1/10 Monster Truck (2) (JCO3242)

Slam-Tech foam tire inserts for 1/10-scale monster trucks come in a two-pack and are designed to sit inside compatible off-road tires to enhance handling in demanding racing conditions. Made from a lightweight, closed-cell Slam-Tech foam with molded geometry, they deliver a smoother roll, better tire balance, and reduced rebound on jump landings for more stable, confident control.

Compared with traditional open-cell inserts, Slam-Tech inserts weigh about 24 g each—roughly 14 g lighter per tire—helping lower unsprung weight for quicker acceleration and improved in-air control. They are white for easy identification and are designed to fit snugly inside JConcepts 2.6-inch tires such as Renegades, Knobs, Launch, Racer, and Runner, providing a race-tested upgrade with a pliable feel thanks to radial-detail removal in the molded Slam-Tech material.
