This is a pair of 1.9" Dual stage closed Cell foam for rock crawlers. Pro-line's inner inserts are made from lightweight and waterproof Blue closed Cell foam while the outer is made from soft open cell foam. When combined they are perfectly sized for Pro-line's 1.9" Xl sized rock crawling tires. The soft outer foam provides maximum grip while maintaining a fully supported sidewall from the inner closed Cell foam for maximum side-hilling performance. Dual stage closed Cell foam are extremely durable and will last through many rugged adventures.
