Yokomo YAU-6734A U6734 Medium Rear Foam Insert for CAT Tyres  [YAU-6734A]

Tune Rear Traction with Foam Inserts

If you want tighter rear control, the Yokomo YAU-6734A U6734 foam inserts are a practical upgrade. Made for 1/10 scale off-road machines, they slip into the rear tyres of both 2WD and 4WD cars to improve stability and tyre contact on uneven ground.

How the Foam Helps

The medium foam provides even pressure across the tyre carcass so the tyre holds shape under braking and corner loads. That leads to steadier traction and fewer surprises when pushing the car hard on loose sections.

Simple Fit Steps

Place the insert evenly inside the tyre, press around the bead to remove creases, then mount onto the wheel. A well-seated insert reduces irregular wear and keeps handling consistent lap after lap.
