Serious RC crawlers and scalers know that the right tire insert can make all the difference between getting stuck and conquering the trail.
These J Concepts React-Cush 1.9" Soft Scaler Inserts (JCO3256) are designed specifically to give you that extra edge in the scale off-road and crawling scene.
Made from soft open cell foam, these inserts offer the perfect amount of cushion and flex.

The narrow width and tall-profile design fits beautifully inside popular class 1 size tires like the Landmines and Bounty Hunters.
Their flat profile helps maintain that authentic scale look while allowing the tire carcass, lugs, and sidewalls to conform naturally to whatever terrain you're tackling.
Different crawling conditions demand different levels of traction and slip.
These soft gray inserts act as the missing link, letting your tires flex and grip where you need it most.

The softness provides excellent performance by allowing continuous terrain adaptation without sacrificing control.

Whether you're running technical rock sections, loose dirt, or trying to maintain momentum on tricky obstacles, these inserts help your tires perform at their best.

They're durable enough to handle repeated runs yet soft enough to deliver that responsive feel crawlers love.

If you've been frustrated with tires that are either too stiff or don't hug the ground properly, give these J Concepts soft inserts a try.
They're a small upgrade that often brings noticeable improvements in how your rig handles real-world crawling challenges.
Pack includes 2 soft inserts.

A smart, affordable way to fine-tune your RC setup for better performance and more fun on the trails.
