Boom Racing 1.9 Dual Stage Soft/Hard Foams For 4.75/4.45 Crawler Tires
Both 4.75" and 4.45" inserts come in soft outer cell foam insert and hard inner closed foam insert.
Soft outer foam provides traction for the tire to sink into the surface for more grip.
A firmer inner closed cell improves sidehill performance and maintains a better sidewall structure.
